Why Do Immune Cells Become Exhausted in the Face of Chronic Infections and Cancers? Persistent viral infections and tumors pose a major challenge to the immune system. Unlike acute infections, where immune cells rapidly eliminate the pathogen and create protective memory, chronic diseases profoundly transform CD8 T cells, which are essential for fighting infected or… Continue reading Why Do Immune Cells Become Exhausted in the Face of Chronic Infections and Cancers?
Do Dairy Products Increase or Reduce the Risk of Breast Cancer?
Do Dairy Products Increase or Reduce the Risk of Breast Cancer? Breast cancer remains the most common cancer among women worldwide and the leading cause of cancer death in this population. Every year, hundreds of thousands of women die from it, making it a major public health issue. Known risk factors include age, obesity, smoking,… Continue reading Do Dairy Products Increase or Reduce the Risk of Breast Cancer?
Can Innovative Imaging Better Predict the Aggressiveness of Benign Brain Tumors?
Can Innovative Imaging Better Predict the Aggressiveness of Benign Brain Tumors? Low-grade brain tumors called oligodendrogliomas are generally considered less aggressive than their high-grade counterparts. However, some of them progress rapidly and recur early, complicating their management. A team of Chinese researchers explored the use of an advanced imaging technique to better identify these high-risk… Continue reading Can Innovative Imaging Better Predict the Aggressiveness of Benign Brain Tumors?
Does Continuous Glucose Monitoring Reduce Serious Complications of Type 1 Diabetes?
Does Continuous Glucose Monitoring Reduce Serious Complications of Type 1 Diabetes? A large study conducted in South Korea reveals that the use of a continuous glucose monitoring system significantly improves the health of adults with type 1 diabetes. This device allows real-time monitoring of blood glucose variations. It thus provides better management of insulin treatment… Continue reading Does Continuous Glucose Monitoring Reduce Serious Complications of Type 1 Diabetes?
Why Are Women Better Protected Against UV-Induced Skin Cancers?
Why Are Women Better Protected Against UV-Induced Skin Cancers? Men develop cutaneous squamous cell carcinomas more often than women, but the biological reasons behind this difference remained poorly understood. A recent breakthrough reveals a protective mechanism specific to women, involving estrogen receptors and a key protein in the cell cycle. Researchers observed that ultraviolet exposure… Continue reading Why Are Women Better Protected Against UV-Induced Skin Cancers?
Could circular RNAs revolutionize treatments for cancer and infectious diseases?
Could circular RNAs revolutionize treatments for cancer and infectious diseases? Linear messenger RNA molecules, used in Covid-19 vaccines, marked a turning point in modern medicine. However, their fragility in the face of enzymes and their ability to trigger undesirable immune reactions still limit their large-scale use. A promising alternative is emerging today: circular RNAs. These… Continue reading Could circular RNAs revolutionize treatments for cancer and infectious diseases?
Does the thymus influence the effectiveness of cancer immunotherapies?
Does the thymus influence the effectiveness of cancer immunotherapies? A major breakthrough in understanding cancer treatments reveals that the state of the thymus plays a key role in the success of immunotherapies. This organ, often overlooked in adults, is essential for the maturation of T lymphocytes, immune cells that target tumors. A recent study shows… Continue reading Does the thymus influence the effectiveness of cancer immunotherapies?
Can Lung Cancer Relapse After Radiotherapy Be Predicted with a Simple Blood Test?
Can Lung Cancer Relapse After Radiotherapy Be Predicted with a Simple Blood Test? Treating localized lung cancer with radiotherapy can save lives, but nearly four out of ten patients see their disease reappear within the following year. A new approach could help identify these relapses earlier. Researchers have shown that a simple blood test can… Continue reading Can Lung Cancer Relapse After Radiotherapy Be Predicted with a Simple Blood Test?
Do Some Gut Bacteria in Preterm Infants Protect Against Serious Diseases?
Do Some Gut Bacteria in Preterm Infants Protect Against Serious Diseases? Bacteria present in the intestines of very premature babies may play a key role in their health. Recent research shows that certain strains of Clostridium, particularly Clostridium perfringens, are capable of breaking down complex sugars found in breast milk, called oligosaccharides. These sugars are… Continue reading Do Some Gut Bacteria in Preterm Infants Protect Against Serious Diseases?
Can Liver Cancers Be Better Targeted Using Lab-Grown Mini-Tumors?
Can Liver Cancers Be Better Targeted Using Lab-Grown Mini-Tumors? Liver cancers are among the deadliest in the world. Their treatment often remains ineffective due to the diversity of tumors and the lack of reliable models to study them. A recent breakthrough shows that it is possible to grow mini-tumors, called organoids, in the laboratory from… Continue reading Can Liver Cancers Be Better Targeted Using Lab-Grown Mini-Tumors?
