蓝舌病病毒(BTV)是一种由库蠓传播的家畜和野生反刍动物的重要疾病。在反刍动物中,BTV具有广泛的细胞嗜性,包括作为病毒复制的重要细胞靶的血管和淋巴管的内皮细胞,以及免疫系统的几种细胞类型,包括单核细胞、巨噬细胞和树突状细胞。因此,细胞进入代表了BTV的一个特殊挑战,因为它感染了多种多样的脊椎动物和无脊椎动物宿主中的许多不同细胞类型。对BTV细胞进入的进一步了解可能会导致新的抗病毒方法,可以阻断病毒在无脊椎动物和脊椎动物宿主之间从细胞到细胞的传播。在这里,我们已经调查了BTV细胞进入使用内皮细胞来自天然牛宿主(BFA细胞)和纯化的全病毒颗粒的低通,昆虫细胞分离的BTV-1的强毒株。我们的研究结果表明,BFA细胞感染的主要进入途径是依赖于肌动蛋白和发动蛋白,并与巨胞饮有一定的特点。使用巨胞饮样进入途径的能力可以解释BTV的不同细胞嗜性,并有助于脊椎动物和无脊椎动物宿主之间的传播效率。
Bluetongue virus (BTV) causes an economically important disease in domestic and wildlife ruminants and is transmitted by Culicoides biting midges. In ruminants, BTV has a wide cell tropism that includes endothelial cells of vascular and lymphatic vessels as important cell targets for virus replication, and several cell types of the immune system including monocytes, macrophages and dendritic cells. Thus, cell-entry represents a particular challenge for BTV as it infects many different cell types in widely diverse vertebrate and invertebrate hosts. Improved understanding of BTV cell-entry could lead to novel antiviral approaches that can block virus transmission from cell to cell between its invertebrate and vertebrate hosts. Here, we have investigated BTV cell-entry using endothelial cells derived from the natural bovine host (BFA cells) and purified whole virus particles of a low-passage, insect-cell isolate of a virulent strain of BTV-1. Our results show that the main entry pathway for infection of BFA cells is dependent on actin and dynamin, and shares certain characteristics with macropinocytosis. The ability to use a macropinocytosis-like entry route could explain the diverse cell tropism of BTV and contribute to the efficiency of transmission between vertebrate and invertebrate hosts.
