Abstract

In recent years life expectancy in Western Societies has dramatically increased with greater numbers of individuals living longer; consequently the prevalence of age-associated diseases such as infections, cancers and autoimmune disease increases. A striking feature of the ageing process is the involution of the thymus. This primary lymphoid organ is instrumental in generating naive T-cell required to successfully defeat against ‘foreign’ and ‘self’ antigens. Much effort has been made to find means of reversing the effects of ageing and a variety of factors have been investigated in a quest to maintain a youthful immune system. In this review we examine some features of immunosenescence and the work undertaken, with particular interest to the role of the cytokine interleukin-7, to further our understanding of the relationship between ageing and development of autoimmunity.
