沙粒病毒的原型淋巴细胞性脉络丛脑膜炎病毒(LCMV)的糖蛋白(GP)是用于基因治疗的慢病毒假型载体的有希望的包膜蛋白。肌营养不良蛋白聚糖(LCMV的一种已知受体)的分布不能解释LCMV-GP-假型的窄向性。在这里,我们检查了LCMV-GP假型的感染是否受到四种细胞表面分子- Axl和Tyro 3(来自TAM家族)以及DC-SIGN和LSEC tin(来自C型凝集素家族)-的表达的影响,这些分子是拉沙病毒(另一种沙粒病毒)的已知受体。所有四种分子都增强了细胞的LCMV-GP-假型感染。这些结果有助于解释LCMV-GP-假型的嗜性,并进一步加深我们对动物LCMV感染的理解。(108字)
The glycoprotein (GP) of lymphocytic choriomeningitis virus (LCMV), the prototype arenavirus, is a promising envelope protein of lentiviral pseudotype vectors for gene therapy. The distribution of dystroglycan, a known receptor for LCMV, cannot explain the narrow tropism of LCMV-GP-pseudotypes. Here, we examined whether infection of LCMV-GP-pseudotypes was affected by the expression of four cell surface molecules - Axl and Tyro3 (from the TAM family) and DC-SIGN and LSECtin (from the C-type lectin family) - that are known receptors of Lassa virus, another arenavirus. All four molecules enhanced LCMV-GP-pseudotype infection of cells. These results help explain the tropism of LCMV-GP-pseudotypes and further our understanding of LCMV infection in animals.
