非人灵长类动物是十分重要的生物医学资源。由于与人类在生理生化、免疫、遗传等方面近似,猕猴是重要的非人灵长类实验动物之一。然而,猕猴作为自然宿主,易感染D型逆转录病毒(simian type D retrovirus,SRV)和T淋巴细胞白血病病毒(simian T lymphotropic virus,STLV)这两种逆转录病毒,并可能会影响AIDS猕猴动物模型等的研究结果。猴B病毒(ceropithecine herpesvirus1,BV)对猕猴及动物从业人员均有危害。云南省拥有较大规模的中国猕猴繁殖种群。基于以上原因,建立SPF级别的中国猕猴种群十分必要。该文应用PCR技术筛查了人工饲养种群中411只中国猕猴的SRV、STLV和BV感染流行情况。结果表明:SRV、STLV和BV的阳性感染率分别为19.71%(81/411)、13.38%(55/411)和23.11%(95/411)。同时比较分析了不同性别及年龄组中国猕猴的病毒感染情况。该研究将有助于建立SPF级别的中国猕猴繁殖种群。

Breast cancer is a common malignant *** is essential to develop suitable animal models for discovering novel preventive and therapeutic *** shrews(Tupaia belangeri chinensis) have a closer evolutionary relationship with humans than do rodents,which have been widely used in laboratory *** breast tumors were identified in tree shrews in 1960s;however,no detailed studies about tree shrew breast tumors have been conducted to ***,we characterized a spontaneous breast tumor from tree shrews by Haematoxylin Eosin(HE) *** tumor was identified as a papillary *** staining(IHC) for progesterone receptor(PR),Ki-67 and cleaved caspase-3 showed that tumor cells were positive for PR,highly proliferative,and less apoptotic compared to normal breast epithelial ***,the spontaneous tumor of tree shrew is very close to human papillary tumors in terms of morphology and pathology and we concluded that tree shrew may be a suitable animal model for breast cancer research.
TRIM5α(tripartite motif protein 5-alpha)蛋白是恒河猴体内一种非常重要的限制因子,能抑制人免疫缺陷病毒(HIV-1, human immunodeficiency virus type 1)、马感染性贫血病毒(EIAV, equine infectious anemia virus)和猫免疫缺陷病毒 ...
