中枢神经系统(CNS)损伤是印度恒河猴SIV感染的结果,在疾病快速进展的感染猕猴中比在常规疾病进展的猕猴中更常见。在这里,我们研究了SIVmac 239感染中国恒河猴的中枢神经系统损害。结果表明,SIV感染可引起猕猴神经系统病理损害,表现为不同脑区出现SIV-RNA阳性细胞、活化的巨噬细胞和丰富的多核巨细胞(MNGC)浸润。高病毒血症、存活时间短(平均16周,快速进展,RP)的动物比常规进展(CP)的动物有更严重的神经病理改变。与RP动物相比,CP猕猴具有较低的病毒血症和更长的存活时间(平均154周)。这些结果表明,SIVmac 239感染中国恒河猴可以作为一个合适的动物模型和替代资源的nueroAIDS的研究。
The central nervous system (CNS) impairment is a consequence seen in SIV infection of rhesus macaques of Indian-origin, which is more common in infected macaques with rapid disease progression than in those with conventional disease progression. Here, we investigated the CNS damages in SIVmac239-infected Chinese rhesus macaques. We demonstrated that SIV infection of Chinese macaques could cause neuropathological impairments, which was evidenced by appearance of SIV-RNA positive cells, the infiltration of activated macrophages and abundant multinucleated giant cells (MNGCs) in the different regions of the brains. The animals with high viremia and short survival time (average of 16 weeks, rapid progression, RP) had severer neuropathological changes than those with conventional progression (CP). As compared with the RP animals, CP macaques had lower viremia and much longer survival time (average of 154 weeks). These findings indicate that SIVmac239 infection of Chinese rhesus macaque can be used as a suitable animal model and alternative resource for nueroAIDS research.
