Research highlights lymph nodes' role in enhancing cancer immunotherapy
New studies reveal that preserving lymph nodes during cancer surgery could improve patient responses to immunotherapy by supporting key immune cells. Led by the Peter Doherty Institute, the research emphasizes lymph nodes' crucial function in training T cells to fight tumors. The findings, published in Nature Immunology, suggest rethinking surgical practices to boost treatment effectiveness.

A new study reveals that decades of endurance exercise, such as running and cycling, may keep the immune system youthful and resilient in older adults. Researchers found that natural killer cells in trained individuals functioned better, showed lower inflammation, and resisted fatigue under stress. The findings suggest physical activity trains the immune system much like it does muscles.
