MmuPV1 infection of Tmc6/Ever1 or Tmc8/Ever2 deficient FVB mice as a model of βHPV in typical epidermodysplasia verruciformis.

ABSTRACT: Typical epidermodysplasia verruciformis (EV) is a rare, autosomal recessive disorder characterized by an unusual susceptibility to infection with specific skin-trophic types of human papillomavirus, principally betapapillomaviruses, and a propensity for developing malignant skin tumors in sun exposed regions. Its etiology reflects biallelic loss-of-function mutations in TMC6 (EVER1), TMC8 (EVER2) or CIB1. A TMC6-TMC8-CIB1 protein complex in the endoplasmic reticulum is hypothesized to be a restriction factor in keratinocytes for βHPV infection. However, the complex is also present in lymphocytes and its loss may compromise cellular immune control of βHPV infection. Indeed, certain primary immunodeficiencies, iatrogenic immunosuppression and AIDS are associated with the atypical form of EV.
