A number of pruritic skin conditions arising in immunocompromised patients are associated with viral infection. Recently, human polyomavirus 7 (HPyV7) has been implicated in the pathogenesis of eruptive pruritic parakeratotic and dyskeratotic dermatoses with distinct "peacock plumage" histology. While expression of HPyV7 viral protein, namely small tumor (sT) antigen, is prominent within lesional tissue, the functional role of HPyV7 in cutaneous pathobiology is not yet known. In this study, we demonstrate a novel role for HPyV7 sT antigen in pathways important for the maintenance of keratinocyte structure and function. In particular, HPyV7 sT was found to dysregulate protein phosphatase 2A through physical inte... More
