传染性脾肾坏死病毒(ISKNV)是虹膜病毒科大细胞病毒属的型种。ISKNV感染具有一种独特的病理现象,即感染细胞被淋巴内皮细胞(LECs)附着。ISKNV介导感染细胞表面的病毒模拟基底膜(VMBM)结构的形成,为LECs提供附着位点。病毒蛋白VP08R是VMBM的重要组成部分。在这项研究中,鉴定了一种新的isknv编码的microRNA,暂时命名为ISKNV-miR-1。ISKNV-miR-1与VP08R编码序列互补,可通过降低VP08R mRNA水平调控VP08R的表达。这表明VMBM的形成可能受到ISKNV的精细调控。
Infectious spleen and kidney necrosis virus (ISKNV) is the type species of the genusMegalocytivirus, family Iridoviridae. Infection of ISKNV is characterized by a unique pathological phenomenon in that the infected cells are attached by lymphatic endothelial cells (LECs). ISKNV mediates the formation of a virus-mock basement membrane (VMBM) structure on the surface of infected cells to provide attaching sites for LECs. The viral protein VP08R is an important component of VMBM. In this study, a novel ISKNV-encoded microRNA, temporarily named ISKNV-miR-1, was identified. ISKNV-miR-1 is complementary to the VP08R-coding sequence and can modulate VP08R expression through reducing its mRNA level. This suggests that formation of VMBM may be under fine regulation by ISKNV.
