We found that rejuvenation of the recipient immunity by inoculation of young CD4^+T cells or a fetal thymus graft led to down regulation of the interleukin 1 receptor type II(IL-1R2) gene in CD4^+T cells and reduced age-related hearing loss in SAMP1 mice, a murine model of human senescence. Our studies on the relationship between age-related systemic immune dysfunctions and neurodegeneration mechanisms open up new avenues of treatment of neurosenescence, including presbycusis, for which there is no effective therapy.

我们发现，通过接种年轻的CD 4 ^+T细胞或胎儿胸腺移植物来恢复受体免疫力，可以下调CD 4 ^+T细胞中的白细胞介素1受体II型（IL-1 R2）基因，并减少SAMP 1小鼠（一种人类衰老的小鼠模型）中与年龄相关的听力损失。我们对年龄相关的系统性免疫功能障碍和神经退行性变机制之间关系的研究为治疗神经衰老开辟了新的途径，包括老年性耳聋，对此没有有效的治疗方法。
