“…Some enveloped viruses such as influenza enter cells by adsorptive endocytosis and then the viral envelope and endosomal membranes fuse to release subviral cores into the cell proper [11,12]. This fusion is mediated by surface proteins which undergo a conformational alteration induced by the acidification of the endosome compartment [45].…”

“…A multi-stage process of 'uncoating' follows whereby the viral genome becomes functional and able to direct virus multiplication. This commences when a proton pump in the membrane acidifies the internal environment of the vesicle, causing the HA to undergo a conformational change which leads to primary uncoatingfusion of the viral and vesicle membranes and entry into the cytoplasm proper of the nucleocapsid [10][11][12]. Details of secondary uncoating can only be surmised but there have to be changes in nucleocapsid such as loss of proteins and/or relaxation of structure so that the viral genome can be exposed sufficiently to be expressed.…”

“…The internalization of a number of envelope viruses occurs by receptor-mediated endocytosis (Marsh, 1984) and if this route is blocked by various means infection can be induced by a brief treatment of low pH conditions (Helenius et al, 1980). To examine whether exposure to low pH would enhance JHM internalization in the rat cell lines, JHM was allowed to adsorb to the RN2 and L6 cells, the infected cells were exposed to a medium of pH 5.5 for 5 to 10 min and the internalization of virus was measured.…”

“…The second route, which appears to be employed by several other enveloped viruses, is endocytosis of the particle into the cell, after which the viral genome is liberated into the cytoplasm (Dales, 1973;Longberg-Holm & Philipson, 1974). Recently, it has been convincingly shown that several enveloped viruses (White et al, 1980(White et al, , 1983Matlin et al, 1981Matlin et al, , 1982Yoshimura et al, 1982) can fuse efficiently with different target membranes at acidic, but not neutral pH and it has been proposed that fusion is involved in the infectious entry process of enveloped viruses, whereby viral genetic material is liberated into the cytosol either at the plasma membrane or from acidic endosomal compartments (Marsh, 1984).T. KIMURA, S. W. GOLLINS AND J. S. PORTERFIELD Sigma).…”
