缺乏经典主要组织相容性复合体I类(MHCI)的小鼠在神经发育方面存在畸变。神经元MHCI表达上调的后果尚未得到检验。我们发现,转基因C57Bl/6小鼠在其中枢神经系统神经元上表达更高水平的自我db,其海马形态和视网膜原状突起发生改变,神经修复反应受损。因此,神经元经典MHCI表达的增强可导致神经回路和神经修复的畸变。这些发现补充了关于MHCI神经生物学活动的不断增长的知识体系,并可能具有潜在的临床相关性。
Mice deficient in classical major histocompatibility complex class I (MHCI) have aberrations in neurodevelopment. The consequences of up-regulated neuronal MHCI expression have not been examined. We found that transgenic C57Bl/6 mice that are engineered to express higher levels of self-Db on their CNS neurons have alterations in their hippocampal morphology and retinogeniculate projections, as well as impaired neurorepair responses. Thus, enhanced neuronal classical MHCI expression can lead to aberrations in neural circuitry and neurorepair. These findings complement a growing body of knowledge concerning the neurobiological activities of MHCI and may have potential clinical relevance.
