I've seen this question about HPV and the reference therein. The link states "Human papillomavirus (HPV) is a DNA virus that presents tropism for epithelial cells, causing infections of the skin and mucous membranes. Replication of HPV occurs in the nuclei of squamous cells and its life cycle is directly related to the differentiation program of the host cell. "
Why does HPV infect squamous epithelial cells and not others, what are the major differences? And why can't that difference be used to provide medication?
