15 صفحه اولRabies Virus-Induced Membrane Fusion Pathway
Fusion of rabies virus with membranes is triggered at low pH and is mediated by the viral glycoprotein (G). The rabies virus-induced fusion pathway was studied by investigating the effects of exogenous lipids having various dynamic molecular shapes on the fusion process. Inverted cone-shaped lysophosphatidylcholines (LPCs) blocked fusion at a stage subsequent to fusion peptide insertion into th...
متن کاملRole of Ca++ in virus-induced membrane fusion. Ca++ accumulation and ultrastructural changes induced by Sendai virus in chicken erythrocytes
Some of the ultrastructural (freeze-etching technique), morphological, and biochemical effects of Sendai virus interaction with chicken erythrocytes have been studied under fusogenic (in the presence of CaCl2) and nonfusogenic (in the presence of ethyleneglycol-bis-N,N'-tetraacetic acid, [EGTA]) conditions. The following phenomena occur, irrespective of the presence of CaCl2 or EGTA: (a) bindin...
متن کاملCell cycle changes and the ability of cells to undergo virus-induced fusion.
Synchronized cells of the mouse leukemic cell line, L5178Y, were examined for their ability to undergo virus-induced fusion. Fusion capacity (defined as the percentage of the original unicellular population that is induced by virus to participate in a fusion event) was measured in cells that were (i) arrested by colcemid, (ii) released from colcemid block, and (iii) released from thymidine bloc...
متن کاملCell-cell fusion induced by the avian reovirus membrane fusion protein is regulated by protein degradation.
The p10 fusion-associated small transmembrane protein of avian reovirus induces extensive syncytium formation in transfected cells. Here we show that p10-induced cell-cell fusion is restricted by rapid degradation of the majority of newly synthesized p10. The small ectodomain of p10 targets the protein for degradation following p10 insertion into an early membrane compartment. Paradoxically, co...
