| persistence of viral dna in the epithelial basal layer suggests a model for papillomavirus latency following immune regression. | rabbit oral papillomavirus (ropv) causes benign and spontaneously regressing oral lesions in rabbits, and is a useful model of disease associated with low-risk human papillomavirus types. here we have adapted the ropv system to study papillomavirus latency. following lesion regression, ropv dna persists at the majority of regressed sites at levels substantially lower than those found in productive papillomas. spliced viral transcripts were also detected. ropv persistence in the absence of diseas ... | 2011 | 21492895 |
