New York, June 5 (IANS): Aerobic exercise, which includes brisk walking, swimming, running, or cycling, can help reprogramme the immune system to reduce tumour growth and amplify the effects of immunotherapy, finds a new study. Published online in Cancer Cell, the study, which focussed on pancreatic cancer, provides new insight into how the mammalian immune system, designed to attack foreign invaders like bacteria, can also recognise cancer cells as abnormal. Exercise-induced increases in levels of the hormone adrenaline cause changes to the immune system, according to researchers at New York University. It includes the activity of cells that respond to signalling protein interleukin-15 (IL-15). The study found that exercise promotes the survival of CD8 T cells sensitive to IL-15, and doubles the number of them homing to pancreatic ductal adenocarcinoma (PDAC) tumours in mice. Such “effector” T cells have been shown by other studies to be capable of killing cancer cells. Ot
New York scientists found exercise boosted the immune system s ability to target cancer cells and increasing survival rates for pancreatic cancer patients and effectiveness of cancer drugs.
