However, as humans age, this precise discrimination wanes. Aged T cells respond poorly to external threats while becoming increasingly reactive toward the body’s own tissues. Our group is dedicated to deciphering the fundamental mechanisms by which aging impairs the T cell’s function, with the ultimate goal of restoring immune precision and resilience in older populations.\u0026lt;/p\u0026gt;\n\u0026lt;p\u0026gt;A potential driver of T cell aging is age-related thymic involution, which alters thymic selection processes and compromises both the quantity and quality of new T cell production. In response to the diminished output from an involuted thymus, existing naïve T cells undergo homeostatic proliferation, and eventually develop functional exhaustion.\u0026amp;nbsp; We are interested in decoding the intrinsic and extrinsic factors that regulate T cell aging. We envision that by modulating T cell sensitivity, we can rejuvenate T cell function, lower the incidence of autoimmunity and cancer, and extend the healthspan of older individuals.\u0026lt;/p\u0026gt;\n\u0026lt;p\u0026gt;We welcome proposals that address core questions of T cell aging.
