This defect leads to the absence of presentation of the major immediate-early protein IE1 to specific CD4(+) T-cell clones when U373 MG cells , used as antigen-presenting cells , are treated with IFN-gamma plus HCMV .
 ( protein: IE1, None) , ( protein: IFN-gamma, None) , ( cell line: CD4(+) T-cell clones, None) , ( cell line: U373 MG cells, None) , ( cell type: antigen-presenting cells, None) , ( protein: major immediate-early protein, None)
