Changes in subpopulations of lymphoid cells of normal (CBA) and autoimmune (NZB) mice were studied as a function of age, by observing migration patterns of Cr labelled lymph node, spleen and thymus cells from donors aged 8 days to 12 months. The method permits analysis of the proportions and numbers of recirculating and non-recirculating lymphocytes in lymphoid compartments. Changes in the lymphoid populations of CBA mice were found, which could be attributed to the normal processes of maturation and senescence. In NZB mice relative and absolute decreases in the recirculating cell content of lymph node and spleen were observed which coincided with the time of development of autoimmunity. The significance of these results, in relation to altered immunocompetence with age, is discussed.
通过观察8天至12个月龄供体的铬标记淋巴结、脾脏和胸腺细胞的迁移模式,研究了正常(CBA)和自身免疫(NZB)小鼠淋巴样细胞亚群随年龄的变化。该方法可分析淋巴样区室中再循环和非再循环淋巴细胞的比例和数量。发现CBA小鼠的淋巴样群体发生了变化,这可归因于成熟和衰老的正常过程。在NZB小鼠中,观察到淋巴结和脾脏再循环细胞含量的相对和绝对下降,这与自身免疫的发展时间一致。讨论了这些结果与年龄相关的免疫能力改变的关系。
