Three Main Inducers of Alphacoronavirus Infection of Enterocytes: Sialic Acid, Proteases, and Low pH.

abstract：:Studies of human papillomavirus (HPV) infection are hampered by the lack of an adequate culture system. The athymic mouse xenograft system permits propagation of HPV, but only a few HPV types have been grown in this manner. To produce an oncogenic type for studies of HPV pathogenesis, a condylomata acuminata lesion fr...
