The influence of ageing on the responses of mouse spleen cells to phytohaemagglutinin and to allogeneic cells was studied in NZB, (NZB×A)F, A and CBA mice. These responses decline with ageing in those strains which are genetically susceptible to autoimmune disease (NZB, (NZB×A)F and A) but not in a non-susceptible strain (CBA). These studies support the view that cellular immunity declines with advancing age in autoimmune-susceptible mice, and suggests that the decline is due to a progressive loss of the thymus-dependent cell pool.
在新西兰黑鼠(NZB)、(NZB×A)F1、A系和CBA小鼠中研究了衰老对小鼠脾细胞对植物血凝素和同种异体细胞反应的影响。在那些对自身免疫性疾病具有遗传易感性的品系(NZB、(NZB×A)F1和A系)中,这些反应随衰老而下降,但在非易感品系(CBA)中则不然。这些研究支持了这样一种观点,即在自身免疫易感小鼠中,细胞免疫随着年龄的增长而下降,并表明这种下降是由于胸腺依赖性细胞库的逐渐丧失所致。
