Endocytic pathways of HPVs. (A) HPV-16, -58, and BPV-1 entered via clathrin/dynamin dependent pathway. HPV-31 might enter via this pathway. (B) The decrease of pH led to endosomal escape of the viral genome. (C) HPV-31 entered via caveolin/dynamin dependent pathway. (D) and (E) Virions were transported between early endosome and caveosome. (F) HPV-16 might be internalized in clathrin- and caveolae-independent pathway, via TEMs.
