摘要: Dysfunction of the immune system in aged individuals includes at least two important factors: accumulation immunocytes with reduced function and lymphocyte clones self-reactive potential. Coincidently, there is a profound reduction germinal center reaction aged. While this likely result age-associated impairment (e.g. diminished response to costimulus, altered lymphokine production etc.), centers may itself make an contribution further immunological dysfunction.
