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.
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.
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.

Organ transplants are a life-saving medical breakthrough that have revolutionized the field of medicine. Kidneys are essential organs that filter waste material from the blood and process it into urine. A typical dialysis patient has a poorer life expectancy than many cancers. Removing one kidney should not affect someone's lifespan or quality of life. A kidney from a living donor in general will have a much better quality because it comes from a healthy and tested person. Kidneys are expected to survive up to twice as long on average in the recipient. Currently, it's not allowed to donate a kidney under any form of payment. However, incentivizing people to donate more is actually a way to starve black markets. It's not to recreate them, it's to undermine them. If you reward a person amply for the sacrifice they've made, something they go into with their eyes open and well informed, that's not exploitation. Organ donation is an incredible gift that can save someone's life so palpably, and everyone should consider donating.

Frances Oldham Kelsey was a scientist who saved thousands of lives by rejecting an application to sell a drug called thalidomide. The drug was widely used in dozens of countries to treat insomnia, workplace stress, and nausea in pregnant women. However, Kelsey found the data on thalidomide's absorption and toxicity inadequate and rejected the application. Her earlier animal-based research demonstrated that drugs could pass from mother to fetus through the placenta, and she believed that thalidomide could cause harm to fetuses. Her decision to reject the application and ask for better evidence saved countless babies from severe birth defects caused by thalidomide. Kelsey's legacy endures as she prioritized facts over opinions and patience over shortcuts, making evidence-based medicine the foundation of reforms that continue to protect people today. By learning about Kelsey's story, students can understand the importance of evidence-based research and the impact of their decisions in science and medicine.
