Context

• These are conditions where the immune system mistakenly attacks the body's own tissues. Common examples include rheumatoid arthritis, lupus, and multiple sclerosis. The immune system's role is to protect against infections, but in autoimmune diseases, it becomes overactive and targets healthy cells.
• Beyond joint damage, RA can affect other systems in the body, including the skin, eyes, lungs, heart, and blood vessels, leading to a range of systemic symptoms.
• Elevated levels of TNF can be detected in the synovial fluid of joints affected by rheumatoid arthritis, indicating its active role in the disease process.
• The development of these therapies marked a shift from treating symptoms of autoimmune diseases to targeting underlying mechanisms, offering a more precise approach to treatment.
• The production of cytokines like TNF can create a feedback loop where the initial immune response is continuously amplified, leading to persistent inflammation if not regulated.
• While effective, TNF inhibitors can suppress the immune system, increasing the risk of infections and potentially leading to other side effects, which must be managed under medical supervision.
• Antibodies are proteins used by the immune system to neutralize pathogens. In this context, a monoclonal antibody specifically targets and binds to TNF, preventing it from interacting with its receptors and thereby reducing its inflammatory effects.

Antibody Therapies' Precision Revolutionizes Pharma's Application of Immunity

Davis narrates how treatment targeting TNF was created and succeeded as a revolutionary remedy for rheumatoid arthritis. He describes the intricate process of creating a suitable anti-TNF antibody, highlighting Jan Vilcek's efforts in generating it in mice and Centocor's subsequent work in humanizing it for use in patients. The chimeric antibody, part mouse and part human, was initially assessed for how well it could treat sepsis, a severe inflammatory response often triggered by bacterial infections, but those efforts proved disappointing.

However, Davis explains how Feldmann's perseverance, aided by James Woody's support within Centocor, led to the testing of the TNF-blocking compound in people with arthritis caused by a rheumatic condition. The initial results were dramatic, with numerous patients experiencing significant alleviation of their symptoms, even running up stairs after being previously wheelchair-bound. While the initial benefits proved short-lived, repeated injections of the treatment provided sustained relief, as confirmed by larger clinical trials. Davis highlights this therapy's achievement as a testament to the power of understanding the molecular details of immune regulation. The precision of this targeted therapy, blocking a single key cytokine, revolutionized rheumatoid arthritis treatment and paved the way for creating other antibody-based therapies for various autoimmune conditions.

Practical Tips

• Create a support network by connecting with others who are also undergoing TNF-targeting treatments. Use social media platforms or local support groups to exchange experiences, tips, and emotional support. This peer-to-peer exchange can provide practical advice on managing side effects and maintaining a positive outlook.
• Encourage curiosity and learning by starting a science book club. Choose books that cover breakthrough medical research and discuss the implications and potential of such work. This can help spread awareness and appreciation for scientific endeavors akin to Vilcek's.
• Explore the potential of biotechnology in everyday products by researching companies that use similar biotechnological advancements to Centocor's and considering their products for your health needs. For example, if you have a condition that could benefit from biologically derived treatments, look into the latest offerings from biotech firms and discuss these options with your healthcare provider.
• You can explore the potential of chimeric antibodies in other medical applications by staying informed about clinical trials and research studies. Since the chimeric antibody mentioned was not successful in treating sepsis, it's possible that it may have efficacy in other conditions. To do this, regularly check databases like ClinicalTrials.gov for ongoing studies related to chimeric antibodies and consider participating in relevant patient advocacy groups or forums to share and receive updates on emerging treatments.
• Partner with a knowledgeable friend or mentor to explore unconventional solutions to your challenge. Collaboration can lead to breakthroughs, much like Feldmann's partnership with Woody. If you're trying to improve your fitness but traditional methods haven't worked for you, team up with a friend who's a fitness enthusiast. Together, you might design a unique workout regimen that combines elements from different disciplines, such as dance, weightlifting, and high-intensity interval training, tailored to your interests and capabilities.
• You can track your symptoms and mobility levels in a dedicated journal to identify patterns and progress. Start by noting down your daily physical and emotional symptoms, along with any activities or treatments you're undergoing. Over time, this can help you pinpoint what alleviates your symptoms and may contribute to improved mobility. For example, you might discover that a certain type of exercise or diet change correlates with better days.
• Engage in complementary activities that may enhance the effectiveness of your treatment. Research suggests that factors like diet, exercise, and stress management can influence treatment outcomes. Experiment with incorporating anti-inflammatory foods into your meals, establishing a moderate exercise routine, or practicing mindfulness meditation to potentially boost the sustained relief you experience from your treatments.
• Engage in low-impact exercise routines designed to complement your targeted therapy for rheumatoid arthritis. Activities like swimming, tai chi, or yoga can improve joint flexibility and strength without overexertion. By integrating regular exercise with your treatment, you may enhance your overall well-being and potentially reduce the need for higher medication doses.

Environmental Influence on Brain-Immune Connection, Circadian Rhythms, Aging

Immune Activity Follows Body's 24-hour Cycle

Immune Cells and Signaling Molecules Show Circadian Patterns, Affecting Timing of Medical Treatments

Davis delves into the fascinating connection between our body's natural circadian rhythm and immunity, explaining how our defenses fluctuate throughout the day. He emphasizes that this cyclical pattern is not simply a matter of immunity being stronger or weaker at specific times, but rather a shift in its overall state, with different immune cells and signaling molecules showing distinct peaks and troughs in their activity. This, in turn, affects how effective medical treatments are.

Davis provides several examples of how our biological clocks influence immune function and proposes that tailoring medical interventions to these rhythms could improve their effectiveness. Studies on rodents given bacterial infections at various times of day show varying immune reactions, with peak activity coinciding with their natural rest period. Similarly, human immune cell numbers and cytokine concentrations fluctuate throughout the day, potentially explaining why symptoms of certain diseases, like asthma and rheumatoid arthritis, are often worse at night or in the morning. These findings suggest that optimizing when medications are taken, like asthma inhalers or vaccines, could significantly improve their impact, achieving better results with lower doses and fewer side effects.

Context

• These are natural, internal processes that regulate the sleep-wake cycle and repeat roughly every 24 hours. They are influenced by external cues like light and temperature.
• This is the practice of timing medical treatments to align with the body's natural rhythms to maximize efficacy and minimize side effects.
• This is the brain's master clock located in the hypothalamus. It synchronizes peripheral clocks in various tissues, including the immune system, to maintain circadian rhythms.
• Studies on rodents often involve controlled environments where light and dark cycles are manipulated to observe changes in immune responses, providing insights into how timing affects health outcomes.
• This is the field of biology that examines periodic (cyclic) phenomena in living organisms and their adaptation to solar- and lunar-related rhythms. It provides insights into how biological rhythms affect health and disease.
• In asthma, airway function often decreases at night due to changes in lung mechanics and increased airway resistance, which can be influenced by circadian variations in bronchial tone and inflammation.

Other Perspectives

• Some treatments may have a wide therapeutic window, making the timing of administration less critical for their effectiveness.
• Circadian-based treatments might not be as beneficial for acute medical situations where immediate intervention is necessary, regardless of the time of day.
• Adherence to medication regimens could be negatively impacted if patients find it difficult to take medications at specific times, especially if these times are inconvenient or conflict with daily activities.

Internal Clock Disruption Impairs Immunity

Davis cautions that disrupting our circadian rhythm can impair immune function. While the brain's primary clock, situated in the hypothalamus, is guided by cycles of light and darkness perceived by the eyes, other clocks operate independently within various tissues and organs. Disturbing these rhythms, whether through persistent time zone changes, sustained night shifts, or the intense environment of space flight, can significantly affect immunity.

Davis highlights the evidence linking circadian disruption to immune dysregulation, pointing to studies on mice simulating time-zone changes and observations of astronauts on space missions. Jet-lagged mice show accelerated tumor growth and decreased survival from cancer, while astronauts experience immune imbalances, including altered immune cell counts, cytokine levels, and reemergence of dormant viruses. He emphasizes that the human body is finely tuned to a 24-hour cycle, and disrupting this rhythm can throw our immune systems off balance, potentially increasing our susceptibility to infections, allergies, and autoimmune diseases.

Context

• Jet lag occurs when there's a mismatch between a person's internal clock and the local time at their destination. This can lead to temporary immune suppression, making travelers more susceptible to infections.
• In space, the absence of a natural day-night cycle and the experience of multiple sunrises and sunsets in a single day can severely disrupt astronauts' circadian rhythms.
• Some viruses, such as the herpes virus, can remain dormant in the body and reactivate under certain conditions, such as stress or immune suppression.
• Understanding the link between circadian disruption and cancer can inform lifestyle recommendations and work policies, such as shift work management, to mitigate health risks.
• Limited access to fresh food and potential nutrient deficiencies in space can impact immune health.
• Hormones like melatonin and cortisol are regulated by circadian rhythms. Melatonin, produced by the pineal gland, promotes sleep, while cortisol, released by the adrenal glands, helps wakefulness and alertness.
• The gut microbiome, which plays a role in immune function, is also influenced by circadian rhythms. Disruption can lead to imbalances in gut bacteria, affecting immunity.

Stress Impacts Immunity Via Cortisol Hormones

Stress Weakens Immunity, Increasing Disease Risk

Davis examines the significant impact stress has on immunity, revealing how chronic stress can weaken our body's defenses and increase our susceptibility to a range of diseases. He explains that stress triggers the release of cortisol, a hormone the adrenals produce, which plays a critical role in getting the body ready for a fight-or-flight response. While cortisol serves a valuable function in short-term stressful situations, prolonged exposure to elevated cortisol levels can weaken immunity.

Davis cites numerous studies documenting the detrimental impact of chronic stress on immunity, including studies on mice, rats, and humans. Stressed animals show impaired immunity against infections and decreased efficacy of vaccinations, while studies on humans reveal similar links between chronic stress and increased vulnerability to viral diseases, slower wound healing, and poorer responses to vaccines. Davis emphasizes that the cumulative effect of persistent stress can weaken the immune system, making individuals more susceptible to an array of ailments, from common colds to more serious illnesses.

Context

• Chronic stress refers to a consistent sense of feeling pressured and overwhelmed over a long period. It can stem from various sources, such as work, relationships, or financial difficulties.
• This is an automatic physiological reaction to an event perceived as stressful or frightening. It involves a series of hormonal and physiological changes that prepare the body to either stay and deal with a threat or to run away to safety.
• Prolonged high cortisol levels are associated with various health issues, including hypertension, cardiovascular disease, and metabolic disorders, which can further compromise immune health.
• Animal studies are often used to understand biological processes because they can be controlled more easily than human studies, allowing researchers to isolate specific variables like stress.
• Chronic stress can decrease the number and effectiveness of lymphocytes, white blood cells that are vital for fighting off infections, thereby increasing vulnerability to diseases.
• This field studies the interaction between psychological processes, the nervous system, and the immune system, highlighting how mental states can influence physical health.

Mind-Body Practices Boost Immunity By Reducing Stress, Mechanisms Unclear

Davis explores the potential for mind-body practices like mindfulness and t'ai chi to boost immunity by alleviating stress. He acknowledges the growing body of evidence suggesting these activities can relieve stress, anxiety, and depression, and potentially improve immune health.

He cautions, however, that the mechanisms by which these practices might influence immunity are not well understood and that the evidence is not entirely conclusive. Many studies examining these practices' possible benefits are limited by small sample sizes, potential bias, and challenges in measuring their impact on overall immune function in real-life situations. Despite these limitations, Davis suggests that mind-body practices may positively influence immunity, which warrants further investigation, particularly as they offer a non-invasive approach to improving physical and mental wellness.

Other Perspectives

• The effectiveness of these practices could be influenced by the quality of instruction and the environment in which they are practiced, which may not be consistent across different settings or practitioners.
• Some individuals may not experience any immune health benefits from mind-body practices due to personal differences in response to these interventions.
• Potential bias is a concern in all forms of research, not just studies on mind-body practices, and there are established methodologies to minimize and account for such biases.
• Non-invasive does not necessarily mean risk-free; improper practice of some mind-body techniques without proper guidance could potentially lead to physical strain or exacerbate psychological issues.
• While further investigation may be warranted, it is important to ensure that such research is cost-effective and does not divert resources from other areas of immunological research with a more established evidence base.

Aging Weakens Immunity, Increasing Vulnerability to Infection and Autoimmunity in Older Adults

Older Individuals Produce Fewer New Immune Cells and Their Immune Cells Are Less Responsive

Davis examines the impact of aging on the immune system, revealing how our ability to fight infections weakens as we age, leading to increased susceptibility to infectious diseases, poorer responses to vaccinations, and a greater risk of developing autoimmune diseases. He explains that this decline in immune function is a multifaceted process, involving a decrease in the production of new immune cells, reduced responsiveness of existing immune cells, and alterations in immune cell communication.

He describes how age-related changes in the marrow, where the body produces immune cells, contribute to this decline. Bone marrow stem cells, which give rise to all immune cell types, become less able to regenerate with aging, causing a diminished supply of new immune cells. Additionally, in older individuals, immune system cells exhibit functional impairments, being less efficient at detecting pathogens and responding to signals that guide them to the site of infection. Davis also notes that the thymus, a small gland where T cells mature and are screened for their ability to distinguish the body’s own cells from foreign ones, shrinks dramatically with age, further contributing to the decline in immune function.

Practical Tips

• Consider intermittent fasting or time-restricted eating as a way to potentially rejuvenate the immune system. Limiting your eating window to 8-10 hours a day and fasting for the remaining 14-16 hours can trigger cellular repair processes that might include the generation of new immune cells. Always consult with a healthcare provider before starting any fasting regimen to ensure it's safe for you.
• Engage in regular, weight-bearing exercises to promote bone density and potentially benefit bone marrow. Activities like walking, jogging, or resistance training apply stress to your bones, which can stimulate bone-forming cells and help maintain marrow function. Start with a 30-minute walk daily and gradually include bodyweight exercises like squats and push-ups.
• You can monitor your immune health by regularly scheduling blood tests that include markers for immune function. By doing so, you'll have a baseline to compare against as you age, which can help you notice changes that might be related to thymus shrinkage. For example, you might track the levels of white blood cells or lymphocyte subsets over time to see if there are significant changes.

Tailoring Vaccines and Immunotherapies for Seniors

Davis discusses the urgent need for new strategies to address the age-related decline in immune function. He highlights the importance of developing tailored immunizations and treatments specifically designed for older individuals, taking into account their unique immune profiles and challenges.

One approach, Davis explains, is to enhance the effectiveness of vaccines by incorporating adjuvants that specifically activate immune system cells in older individuals. He cites the example of a flu vaccine that included a bacterial molecule called flagellin, which immune systems across all age groups readily recognize. This flagellin-containing vaccine elicited significantly stronger immune responses in both elderly mice and humans compared to standard flu vaccines. Another strategy, he suggests, involves optimizing the timing of vaccinations, capitalizing on the circadian rhythm. Studies show that administering the flu vaccine during morning hours, when immune cells are particularly active, can boost the antibody reactions of older adults. Davis emphasizes that understanding the intricacies of how immunity changes with age is crucial for developing effective medical interventions to improve health and well-being in later life.

Practical Tips

• Create a sleep sanctuary to improve the quality of your rest, as good sleep is crucial for immune function. Invest in blackout curtains, use comfortable bedding, and keep electronic devices out of the bedroom. Establish a calming pre-sleep routine, like reading or meditating, to signal to your body that it's time to wind down.
• Volunteer with organizations that support elderly health to gain firsthand experience with the challenges they face. Offer to assist in creating informational materials or organizing events that educate the public about the need for specialized immunizations and treatments for the older population. Your direct involvement can provide valuable insights into the practical applications of age-specific healthcare.
• You can discuss the potential benefits of flagellin-enhanced flu vaccines with your healthcare provider to make informed decisions about your vaccinations. When you have your annual check-up or flu shot appointment, bring up the topic of flagellin and its role in boosting immune responses, especially if you're in the elderly demographic. Ask if there are any clinical trials or upcoming vaccines that incorporate this component that you might be eligible for.
• Adjust your sleep schedule to ensure you're well-rested before morning vaccinations. A good night's sleep can help your immune system function optimally. To prepare for a morning vaccine appointment, aim to get a full 7-9 hours of sleep the night before.

Cancer Immunotherapy's Revolutionary Potential in Disease Fighting

Cancer Once Invisible, now Tackled by Immune System Research

The Role of Immunity in Cancer Detection and Treatment

Davis highlights the evolving understanding of how immunity plays a role in cancer, dispelling the misconception that cancer cells can't be seen by our body's defenses. While cancer, unlike infections, is not caused by external invaders, the genetic and epigenetic mutations that transform normal cells into cancerous ones create unique molecular signatures that can be identified by the immune system. Davis emphasizes how this recognition of cancerous cells as abnormal paves the way for harnessing the immune system's power to fight the disease.

He describes the pioneering work of Thierry Boon, who identified specific protein fragments modified in cancer cells that trigger recognition by T cells. These tumor-associated antigens, as they are called, act as flags that alert the body's defenses to the existence of cancerous cells. Davis explains that immune defenses continually monitor for such errors, keeping a watchful eye out for cells displaying these telltale signs of transformation. This recognition of cancer cells by our body's defenses forms the basis for immunotherapies, which aim to enhance the natural defenses to combat the disease.

Context

• Unlike genetic mutations, epigenetic changes do not alter the DNA sequence but affect gene expression. These changes can also lead to the production of proteins that are atypical for normal cells, serving as markers for the immune system.
• Research into tumor microenvironments has shown that some cancer cells can evade immune detection by downregulating the expression of antigens or by producing molecules that suppress immune responses.
• Thierry Boon's research was pivotal in identifying how specific mutations in cancer cells create new antigens that can be recognized by the immune system, laying the groundwork for developing targeted cancer immunotherapies.
• These are drugs that help the immune system recognize cancer cells more effectively by blocking proteins that prevent T cells from attacking cancer cells, often used in conjunction with the identification of TAAs.
• Tumor-associated antigens are proteins or fragments that are either unique to cancer cells or are present in much higher amounts than in normal cells, making them targets for immune recognition.
• This approach uses proteins that modulate the immune system, such as interleukins and interferons, to enhance the body's natural response to cancer.

Checkpoint Blockers Unleash T Cells, Showing Dramatic Cancer Therapy Results

Davis delves into an innovative method for treating cancer: immune checkpoint therapy. This strategy, pioneered by Jim Allison, exploits the body’s innate immune braking mechanisms to unleash T cells and enhance their ability to target cancer cells. He explains that T cells, while capable of mounting powerful attacks against cancerous cells, are equipped with built-in brakes that prevent excessive or prolonged immune responses. These brakes, as receptor molecules on the T cell surface, act as checkpoints, ensuring that the immune response remains under control and doesn't attack healthy tissues.

Davis explains that Allison's groundbreaking research resulted in creating antibodies that block these checkpoint receptors, effectively releasing the brakes on T cells and amplifying their ability to attack tumors. He describes the discovery of CTLA-4, a checkpoint receptor that normally dampens T cells' activation. By using a monoclonal antibody to inhibit CTLA-4, Allison's team found they could dramatically enhance the immune response against tumors in mice, leading to complete tumor regression. This success in animal models led to the development of ipilimumab (Yervoy), an anti-CTLA-4 antibody, which became the first checkpoint inhibitor approved for melanoma patients. Davis emphasizes how checkpoint inhibitors represent a paradigm shift in cancer treatment, moving from directly targeting cancer cells to manipulating the body's inherent immune mechanisms to fight the disease.

Practical Tips

• You can raise awareness about the importance of immunotherapy research by starting a social media campaign that shares survivor stories and current research advancements. By doing this, you create a platform for individuals who have benefited from immunotherapy to share their experiences, which can inspire donations to research foundations and encourage public interest in supporting further developments in this field.
• Engage in moderate, regular exercise to support immune function. Physical activity has been shown to have a positive effect on the immune system, including the balance of T cell activity. By exercising regularly, you're not directly manipulating T cell brakes, but you are contributing to an overall healthy immune system, which includes the proper functioning of T cells.

Other Perspectives

• The cost and accessibility of checkpoint inhibitors can be prohibitive for many patients, limiting the widespread application of this therapy.
• The effectiveness of CTLA-4 inhibition can vary greatly among patients, with some experiencing significant benefits and others having little to no response, indicating a need for personalized approaches to treatment.
• The approval of ipilimumab for melanoma patients was a significant milestone, but it should be acknowledged that not all patients respond to this treatment, and there are cases of resistance or relapse.
• While checkpoint inhibitors do leverage the immune system, they are not the only or first treatments to do so; earlier forms of immunotherapy, such as cytokine therapy and cancer vaccines, have also utilized the immune system to fight cancer.

Immune System Advances Offer Hope for Addressing Illnesses

Researchers Explore Immune Cell Engineering and Therapies Beyond Cancer

Davis highlights the ongoing research exploring various strategies to modify immunity for therapeutic purposes, offering hope for new treatments beyond cancer. One promising approach, he explains, involves engineering immune cells to zero in on and destroy diseased cells. He discusses CAR T cell therapy, pioneered by Carl June, which involves genetically modifying a patient's T cells to express a hybrid receptor that recognizes antigens. This engineered receptor combines an antibody fragment that recognizes a specific target on cancer cells with a signaling domain that triggers T cell activation, effectively turning the patient's own T cells into "guided missiles" programmed to seek and destroy their cancer cells.

Beyond cancer, Davis suggests that T cells could also be engineered with CARs to target other diseased cells, potentially offering new treatment options for autoimmune conditions. He presents an example of research using CAR T cells engineered to kill off immune cells that are assaulting the body's tissues in autoimmune diseases. While this technology is still in its early stages of development, the potential to reprogram immunity with such precision offers exciting possibilities for treating a wider variety of diseases.

Practical Tips

• Consider enrolling in a citizen science project that focuses on medical research. These projects often need non-experts to help with data collection or analysis, which can indirectly support the development of treatments that involve engineering immune cells.
• Consider donating blood or registering as a bone marrow donor, as these biological materials can be critical for patients undergoing treatments that modify T cells. Your contribution could potentially be part of a life-saving therapy for someone with cancer, and the process of donation is usually simple and well-guided by medical professionals.
• Encourage conversations about personalized medicine with your healthcare provider. Next time you have an appointment, ask about the latest advancements in treatments like CAR T-cell therapy and express your interest in such innovations. This can signal to healthcare professionals the growing patient interest in cutting-edge treatments, potentially influencing the adoption of new therapies as they become available.
• Volunteer for clinical trials if you have an autoimmune disease, provided you meet the inclusion criteria. This direct involvement can contribute to the advancement of CAR T cell therapies. Before deciding to participate, consult with your healthcare provider to understand the potential risks and benefits.
• You can monitor emerging technology trends by setting up a personalized Google Alert. Choose keywords related to the technology you're interested in, and Google will send you email updates when new content is published online. This way, you'll stay informed about the latest developments without needing to actively search for information.

Challenges: Identifying Reliable Biomarkers for Patient Responses and Overcoming Complex Disease Adaptations

Davis acknowledges the challenges in developing and implementing these new immunotherapies, emphasizing the need for further research to address key limitations. A key hurdle, he explains, is the unpredictable nature of patient responses. While checkpoint inhibitors and CAR T cell treatments have shown remarkable results in some patients, they don't work for everyone, and some patients experience significant side effects.

Davis emphasizes the need for reliable biomarkers, measurable indicators that can predict which patients are probable to react positively to a specific therapy and which ones are at risk for adverse effects. He discusses the ongoing research to identify these biomarkers, analyzing factors such as specific immune cell receptor proteins, the genetic mutations present in tumor cells, and the overall state of the immune system. Another challenge, Davis explains, is the adaptability of the immune system. Both cancerous and viral entities, constantly evolving to evade immune detection, can develop resistance to immunotherapies. Addressing these challenges, he suggests, requires continuous research and collaboration to refine existing therapies, develop new ones, and stay ahead of the ever-changing medical landscape.

Context

• Significant side effects can lead to the discontinuation of therapy, requiring alternative treatment strategies to be considered for affected patients.
• Biomarkers can be used in the development of new drugs by helping to identify which patients are most likely to benefit from a new therapy, thus improving the efficiency of clinical trials.
• Viruses, especially RNA viruses, have high mutation rates, allowing them to quickly adapt and potentially escape immune detection.

Other Perspectives

• The unpredictability of patient responses could be argued to be less of a hurdle and more of a limitation of our current understanding, which is expected to evolve as research continues.
• The term "remarkable results" is subjective and could be misleading, as what is considered remarkable can vary among patients, clinicians, and researchers, depending on their expectations and standards for treatment success.
• The emphasis on biomarkers might inadvertently reduce the perceived importance of patient-reported outcomes and quality of life measures, which are also crucial for evaluating the success of immunotherapies.
• The issue may not be the adaptability of the immune system per se, but rather our current understanding and ability to manipulate it, which could improve with more research and technological advancements.
• The pace of medical innovation may outstrip the ability of regulatory bodies to ensure the safety and efficacy of new therapies, potentially leading to public health risks.
