Ageing and genetic control of immune responsiveness.
Ageing is associated with a progressive decline of immune responsiveness to exogenous antigens and increasing incidence of autoimmune phenomena. Many studies have been focussed on the mechanisms of the immunologic features of ageing. Alterations in cellular components of the immune system rather than in the extracellular milieu seem to account for most of the variations of immune competence in ageing.
