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.
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.
Scientists have developed a groundbreaking treatment for blood cancer using off-the-shelf T-cells. The CALM clinical trial evaluated the potential of UCART19, an "off-the-shelf" CAR-T cell product, against adult patients with B-ALL. The results were recently published in The Lancet Haematology and Cancer Research Communications, showing that 48% of treated patients achieved complete remission lasting an average of 7.4 months. This new approach offers a more efficient and effective alternative to traditional CAR-T cell therapy, providing hope for patients with relapsed or treatment-resistant blood cancers.

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.
Severe stress triggers biological age to increase, but it can be reversed. Surgery, pregnancy, and COVID-19 are studied in humans and mice. Researchers found that biological age increased in situations of severe physiological stress but was restored when the stressful situation resolved. This study challenges the concept that biological age can only increase over a person’s lifetime and suggests that it may be possible to identify interventions that could slow or even partially reverse biological age.
Cancer is a mysterious and deadly disease that claims the lives of 1500 Americans every day. But why is it so common, and why does treatment often fail? In "Cancer: The Evolutionary Legacy", leading researcher Mel Greaves offers clear and convincing answers to these questions by looking at cancer through a Darwinian lens. Greaves argues that human development has trapped us in a nature-nurture mismatch, causing cancer to thrive. With compelling examples from history and modern research, this fascinating book sheds light on the evolutionary context of cancer and its implications for prevention and treatment. Recommended for biology students, medical professionals, and anyone interested in the evolutionary origins of disease, "Cancer: The Evolutionary Legacy" offers a fresh perspective on this complex and elusive disease. With its lucid and engaging style, this book is accessible to readers of all backgrounds and provides a comprehensive overview of cancer research and treatment. Additionally, those interested in the history of medicine and public health will find the compelling examples from history, including the epidemic of scrotal skin cancer in 18th-century chimney sweeps, to be particularly interesting.
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.
Did you know that selecting the embryo with the lowest risk for a given disease can cut the risk for that disease by almost half? This is particularly true for disorders such as schizophrenia and Crohn’s disease. However, the selection process may not lead to significant improvements in non-disease traits such as intelligence. Moreover, the use of preimplantation genetic screening (PES) raises concerns about psychological well-being, social values, and ethics. Learn more about the potential benefits and risks of PES, and how it may impact our society and individuality.

Cancer is a mysterious and creepy thing, and understanding it is crucial to fighting it. Cancer cells are unstable and selfish, only working for their own short-term benefit. They trick the body into building new blood vessels to feed them, but this can also become their undoing as they continue to mutate. Large animals seem to be immune to cancer, which scientists explain through two main ways: evolution and hypertumors. Evolution means that large animals invest in better cancer defenses, while hypertumors are the tumors of tumors. The solution to the paradox may actually be something different, but researchers still aren't sure what it is. Learning about the nature of cancer cells and cancer defenses can help you understand this complex and important topic.

Mitochondria are often referred to as the powerhouses of the cell and for good reason. These tiny organelles are responsible for producing the energy that our cells need to function. In this write-up, we'll explore the magic of mitochondria and why they are so important to our health and well-being. Did you know that mitochondria are sometimes referred to as the "second genome"? This is because they have their own DNA and can replicate independently of the cell's nucleus. This discovery, made by Dr. Douglas C. Wallace in the late 1970s, revolutionized our understanding of cellular biology. Another interesting fact about mitochondria is that they are thought to have originated from a symbiotic relationship between early cells and primitive bacteria. Over time, the two organisms evolved together to form the cells that make up our bodies today. This theory, known as the endosymbiotic theory, was first proposed by Dr. Lynn Margulis in the 1960s. So, what exactly do mitochondria do? Well, they are responsible for producing energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration. This energy is then used by our cells to carry out all of their functions, from moving and growing, to repairing and reproducing. It's important to note that our cells can't survive without energy, and without mitochondria, we wouldn't be able to produce enough energy to support our bodies. This is why mitochondria are so critical to our health and well-being. By learning more about the magic of mitochondria, you'll gain a deeper understanding of cellular biology and the role that these tiny organelles play in our lives. So, get reading, reflecting, and exploring!
Vaccines are likely the most important public health intervention of the last 100 years, having saved over a billion lives. They have led to a massive reduction in child mortality in sub-Saharan Africa and can even prevent cancer. A world without vaccines would be unimaginable, with outbreaks of disease regularly all over the world. Vaccines are the only public health intervention that can bring equality, as they protect not only oneself but also one's family and community. While anti-vaccination fears have been around for over a century, it's important to engage with people where they are and understand their context, concerns, and experiences with health and vaccines. Taking a vaccine is not just a personal choice, but a moral choice that affects other people. Vaccines are fundamental to the privileges we have in the modern world and make it a safe place for most of us to be.
Are you stressed about aging and the risks it poses to your health? A new study published in Cell Metabolism offers hope. According to Smithsonian Magazine, researchers found that biological age, which is measured by the state of DNA, can be reversed after a stressor subsides. This means that even if stress increases your biological age and raises the risk of certain diseases, it can be reversed once the stress is gone. The study looked at both mice and humans, and the findings are fascinating. Read the full article to learn more about the study's methodology and results.
