Abstract
Infection of human fibroblast cells with human cytomegalovirus (HCMV) causes down-regulation of cell surface expression of MHC class I. A recombinant mutant HCMV which fails to down-regulate class I heavy chain expression is described. A method of controlling down-regulation of MHC class I expression in a cytomegalovirus infected cell, a pharmaceutical composition, a vaccine composition, a method of preventing or reducing susceptibility to acute cytomegalovirus in an individual, and a virus based gene therapy vector are also described.
Claims1
A cell transformed or transfected with a vector selected from the group consisting of an adenovirus, adeno-associated virus, retrovirus, and herpes simplex virus, said vector comprising a gene sequence encoding the open reading frame US2 of the human cytomegalovirus genome, wherein said gene sequence is expressed in said cell.
