HIV, the virus that causes AIDS, is a master of disguise. It can change its outer coat of proteins frequently, making it hard for the immune system to recognise and destroy it. HIV targets Helper T cells, which act as the air traffic controllers of the immune system, coordinating the efforts of other immune cells. If Helper T cells disappear, the whole immune system would have trouble fighting not just HIV but many other illnesses as well. Boosting the immune system against HIV requires getting the Helper T cells back in control. Learning about the immune system and how it works can help you understand how HIV affects the body and how to boost your immune system against it. By exploring this topic through reading, reflection, writing and self-directed projects, you can gain a deeper understanding of the immune system and how to protect yourself from harmful intruders like viruses and bacteria.

Bacteria, once thought of as harmful, have been found to have the potential to fight cancer. Synthetic biologists have discovered a way to program bacteria to safely deliver drugs directly to tumors. Unlike traditional treatments, bacteria can selectively grow inside tumors, avoiding healthy tissues. By manipulating their DNA, bacteria can be instructed to synthesize different molecules, including those that disrupt cancer growth. With the help of biological circuits, bacteria can be programmed to sense specific conditions and respond to tumors while avoiding healthy tissue. This approach has proven promising in scientific trials using mice, and it also stimulates the immune system, priming it to attack untreated tumors. Bacteria can also serve as sophisticated sensors, monitoring sites for future disease. Advances in technology and synthetic biology have created excitement around a future of personalized medicine driven by bacteria.

UCLA scientists have identified how immune cells detect and respond to cancer cells, leading to better personalized immunotherapies for patients who do not respond to treatment. Checkpoint inhibitors improve T cells' ability to recognize and attack cancer cells, and the study showed that when immunotherapy is effective, it directs a diverse repertoire of T cells against a small group of selected mutations in a tumor. The researchers adapted advanced gene-editing technology to make unprecedented observations about immune responses in patients with metastatic melanoma receiving anti-PD-1 "checkpoint inhibitor" immunotherapy.

Did you know that spending just a few weeks in space can lead to a 20% loss of muscle mass? That's because in microgravity, astronauts don't need to use their muscles as much to stay upright or move around. This lack of exercise leads to a breakdown in muscle tissue and a loss of strength. But it's not just astronauts who are affected by muscle degradation. People on bed rest, those with certain medical conditions, and even the elderly can experience a loss of muscle mass and function. So what's happening on a cellular level? When muscles aren't used, they begin to break down proteins for energy. This process, called protein degradation, can lead to the loss of muscle mass and function. But don't worry, researchers are working hard to find ways to combat muscle degradation in space and on Earth. One approach is to use exercise machines that simulate gravity, which have been shown to maintain muscle mass in astronauts. Other research has focused on using drugs to block the protein degradation process and promote muscle growth. Leading academics in the field of muscle degradation include Dr. Robert Fitts, a professor of biology at Marquette University, who has researched the effects of microgravity on muscle mass and function. Dr. Lori Ploutz-Snyder, a professor at the University of Michigan, has also studied muscle atrophy and is working on developing exercise programs to prevent it. Overall, muscle degradation is a serious concern for both astronauts and people on Earth. By learning more about the causes and potential solutions, we can work towards maintaining healthy muscles and preventing muscle loss.

As we grow older, our bodies undergo many changes, including changes in our metabolism. Metabolism refers to the chemical processes that occur in our bodies to maintain life. These processes are essential for providing energy, building and repairing tissues, and eliminating waste products. As we age, our metabolic pathways can become altered, leading to various age-related diseases and conditions. One example of a metabolic pathway that is affected by aging is the mitochondrial electron transport chain (ETC). The ETC is responsible for producing ATP, the primary source of energy for our cells. As we age, the function of the ETC can become impaired, leading to a decrease in ATP production and an increase in oxidative stress. This can contribute to age-related diseases such as Alzheimer's disease, Parkinson's disease, and diabetes. Another example is the mTOR (mechanistic target of rapamycin) pathway, which regulates cellular growth and metabolism. Studies have shown that inhibiting the mTOR pathway can increase lifespan in various model organisms, including mice. This has led to increased interest in developing drugs that target this pathway as a potential anti-aging strategy. One of the leading academics in this field is Dr. David Sinclair, a Professor of Genetics at Harvard Medical School. Dr. Sinclair's research has focused on the role of metabolism in aging and age-related diseases, and he has made significant contributions to the field. For example, his research has shown that supplementing with NAD+, a molecule involved in energy metabolism, can improve various aspects of aging in mice. Another leading academic in this field is Dr. Valter Longo, a Professor of Gerontology and Biological Science at the University of Southern California. Dr. Longo's research has focused on the role of fasting and caloric restriction in aging and age-related diseases. His work has shown that periodic fasting can have a range of health benefits, including improving insulin sensitivity and reducing inflammation. In conclusion, the study of metabolic pathways in aging is a fascinating and rapidly growing field. By understanding the complex interplay between metabolism and aging, we can better understand the underlying causes of age-related diseases and conditions. Students who are interested in this topic can continue to explore it through reading and research, or by pursuing their own experiments and projects. With the right tools and resources, they can make meaningful contributions to this exciting field and help improve our understanding of aging and metabolic pathways.

Childhood cancer is a devastating disease that affects thousands of children every year. However, as cancer is more likely to occur in adults rather than children, research on childhood cancer is often underfunded, leading to fewer treatment options and lower survival rates. One of the biggest challenges in treating childhood cancer is the risk of long-term side effects from chemotherapy and radiation. These treatments can cause developmental delays, learning disabilities, and even secondary cancers later in life. As a result, new treatment strategies are being developed to minimize these risks. One of the most promising new approaches is immunotherapy, a type of treatment that harnesses the power of the immune system to attack cancer cells. CAR T-cell therapy, in which T-cells are genetically engineered to recognize and attack cancer cells, has shown particularly promising results in clinical trials. Another challenge in treating childhood cancer is the lack of targeted therapies. Unlike adult cancers, childhood cancers often have no known driver mutations that can be targeted with precision medicine. Researchers are working to identify new drug targets and develop new treatments that can attack cancer cells while sparing healthy cells. Dr. Kimberly Stegmaier, an oncologist and researcher at the Dana-Farber Cancer Institute, is one of the leading experts in childhood cancer research. She and her team are working to identify new drug targets and develop targeted therapies for childhood cancers. They are also studying the genetic and molecular characteristics of childhood cancers to better understand how they develop and how they can be treated. In conclusion, childhood cancer presents unique challenges that require innovative solutions. While underfunded research and the lack of targeted therapies have made progress difficult, recent developments in immunotherapy, such as CAR T-cell therapy, show promising results. As we continue to fight for a cure, let us also remember the children and families affected by this disease and strive to support them in any way we can.
