Adaptive as well as innate immune traits are variously affected by environmental and genetic influences, but little is known about the impact of genetics on the diversity, differentiation and functionality of γδ T cells in humans. Here, we analyzed

CD4(+) regulatory T cells (Tregs) are a distinct population of T cells involved in maintaining peripheral tolerance to self-antigens. Several studies have shown increased frequency and number of Tregs in the elderly. Whether such an increase has any

Influenza remains a major pathogen in older people. Infection with CMV and the accumulation of late-differentiated T cells associated with it have been implicated in poor Ab responsiveness to influenza vaccination in the elderly, most of whom are CMV

The low percentages of naive T cells commonly observed in elderly people are thought to be causally associated with mortality, primarily from infectious disease, and are taken as a hallmark of “immunosenescence”. Whether low levels of naive cells

Seropositivity for CMV is one of the parameters of the “immune risk profile” associated with mortality in longitudinal studies of the very elderly and may accelerate immunosenescence. Thus, any genetic factors influencing human longevity may be a
