What is the lifespan of T cells?

These methods were later used to confirm that memory T cells live for six months or less in healthy humans (Westera et al., 2013), whereas naive T cells can live for up to nine years (Vrisekoop et al., 2008). Thus, a long life is not a key characteristic of memory T cells.

Who has a weakened immune system?

Why does T cell function decrease with age?

The effects of ageing on T cells are more researched and documented than for any other cell populations, primarily because these are the effectors and regulators of the immune response and because of thymic involution. This natural phenomenon reduces the output numbers of naïve T cells with increasing age.
