Australian researchers identify age-related thymus cell types contributing to weakened immunity.

Australian researchers from the Walter and Eliza Hall Institute discovered two new cell types causing the thymus, a key immune organ, to lose function as people age. The thymus shrinks with age, replacing T cell growth areas with fatty tissue, resulting in weakened immunity. The scientists' findings may lead to new ways to restore the thymus' function and maintain immunity levels as people age, potentially benefiting vulnerable patients with weakened immune systems.
