obsolete viral entry into host cell via caveolin-mediated endocytosis followed by genetic injection through the endosome membrane true 2011-07-27T02:57:55Z This term was made obsolete because it doesn't represent a genuine process. The term injection is mostly used for prokaryotic viruses where there is no endocytosis. GO:0075515 viral entry into host cell via caveolin-mediated endocytosis followed by genetic injection through the endosome membrane jl biological_process viral entry into host cell via caveolae-mediated endocytosis followed by genetic injection through the endosome membrane OBSOLETE. The uptake of a virus into a host cell that begins when material is taken up into plasma membrane caveolae which then pinch off to form endocytic caveolar carriers containing the virus. The caveolar carriers then deliver their viral content to early endosomes, and the process ends when viral nucleic acid is released into the host cytoplasm by its injection through the endosome membrane.
