人乳头状瘤病毒(HPV)除可引起良性肿瘤和疣外,还与癌有关,主要是鳞癌和疣状癌。 乳头状瘤病毒(PV)是DNA亲上皮病毒,感染宿主后染色体一般不插入宿主染色体中,但在宿主细胞核中保留许多环状DNA。PV有宿主特异性但各种动物PV均可感染人体,现已分离的HPV至少有42型,但均有共同的内抗原。HPV的类型,基因组成,免疫反应和其他因素均影响其感染结 Human papilloma virus (HPV) in addition to causing benign tumors and warts, but also with the cancer, mainly squamous and verrucous carcinoma. Papillomavirus (HPV) is a DNA pro-epithelial virus. Chromosomes are generally not inserted into the host chromosome after infection of the host, but retain many circular DNA in the host cell nucleus. PV has host specificity but all kinds of animal PV can infect human body. At present, there are at least 42 types of HPV that have been isolated, but all have common internal antigens. The type of HPV, the composition of the genome, the immune response, and other factors affect the infection
