一 哺乳动物衰老过程中最显著的变化是 胸腺退化,与对以下疾病的易感性增加有关 感染、自身免疫性疾病和癌症。为了延缓与年龄有关的 我们已经开发出了针对性的抗氧化剂, 质体醌基癸基三苯基膦(SkQ 1)。在这里,我们报告说,在 低剂量SkQ 1(250 nmol/kg/天)抑制年龄依赖性 正常(Wistar)和衰老倾向(OXYS)的胸腺退化 大鼠SkQ 1保留了器官的总重量和体积, 胸腺皮质和髓质、胸腺细胞结构和CD 3+数量, CD 4+和CD 8+细胞。此外,SkQ 1特别有效 在易衰老的老鼠身上。 因此,SkQ 1减缓了与年龄相关的 免疫系统的下降,解释了这种化合物的预防作用, 感染引起的啮齿动物死亡,我们组以前描述过。
One of the most striking changes during mammal aging is a progressive involution of the thymus, associated with an increase in susceptibility to infections, autoimmune diseases and cancer. In order to delay age-related processes, we have developed mitochondria-targeted antioxidant plastoquinonyl decyltriphenyl phosphonium (SkQ1). Here we report that, at low doses, SkQ1 (250 nmol/kg per day) inhibited age-dependent involution of the thymus in normal (Wistar) and senescence-prone (OXYS) rats. SkQ1 preserved total weight and volume of the organ, the volume of thymic cortex and medulla, the thymic cellularity, and the number of CD3+, CD4+, and CD8+ cells in the thymus. Moreover, SkQ1 was especially effective in senescence-prone rats.   Thus SkQ1 slows down age-linked decline of the immune system, explaining prevention by this compound of infection-caused death in rodents, previously described in our group.
