BK virus (BKV), also known as Polyomavirus Polyomavirus The life cycle of polyomavirus begins with Enter a host cell. The cellular receptors for polyoma viruses are the sialic acid residues of glycans, usually gangliosides. Attachment of polyoma viruses to host cells is mediated by the binding of VP1 to cell surface sialylated glycans. https://en.wikipedia.org › Wiki › Polyomaviridae
