Respiratory syncytial virus (RSV), a member of the Paramyxoviridae family, encodes a small hydrophobic (SH) protein of unknown function. Parainfluenza virus 5 (PIV5), a prototypical paramyxovirus, also encodes an SH protein, which inhibits tumor necrosis factor alpha (TNF-alpha) signaling. In this study, recombinant PIV5 viruses without their own SH but containing RSV SH (from RSV strain A2 or B1) in its place (PIV5DeltaSH-RSV SH) and RSV lacking its own SH (RSVDeltaSH) were generated and analyzed. The results indicate that the SH protein of RSV has a function similar to that of PIV5 SH and that it can inhibit TNF-alpha signaling.
呼吸道合胞病毒（RSV）是副粘病毒科的成员，编码一种功能未知的小疏水（SH）蛋白。副流感病毒5型（PIV5）是一种典型的副粘病毒，也编码一种SH蛋白，该蛋白可抑制肿瘤坏死因子α（TNF-α）信号传导。在本研究中，构建并分析了缺失自身SH蛋白但在其位置含有RSV SH蛋白（来自RSV A2或B1株）的重组PIV5病毒（PIV5DeltaSH-RSV SH）以及缺失自身SH蛋白的RSV（RSVDeltaSH）。结果表明，RSV的SH蛋白具有与PIV5 SH蛋白相似的功能，并且它可以抑制TNF-α信号传导。
