流行性感冒(流感)病毒侵袭的目标是呼吸道粘膜上皮细胞,偶有侵袭肠粘膜的病例,则会引起胃肠型流感。病毒侵入体内后依靠血凝素吸附于宿主细胞表面,经过吞饮进入胞浆,病毒包膜与细胞膜融合释放出含ss-RNA、ss-RNA的8个节段在胞浆内编码RNA多聚酶、核蛋白、基质蛋白、膜蛋白、血 The target of influenza (influenza) virus invasion is respiratory mucosal epithelial cells, cases of occasional invasion of intestinal mucosa, it will cause gastrointestinal flu. After the virus invades the body, it relies on the hemagglutinin adsorbed on the surface of the host cell. After swallowing into the cytoplasm, the viral envelope and the cell membrane are fused to release the RNA polymerase containing 8 segments of ss-RNA and ss-RNA in the cytoplasm, Nucleoprotein, matrix protein, membrane protein, blood
