Specificity of human natural killer cells in limiting dilution culture for determinants of herpes simplex virus type 1 glycoproteins.


The frequency and specificity of human cells with natural killer (NK) cytotoxic activity for herpes simplex virus type 1 (HSV-1)-infected targets was measured by limiting dilution culture. The frequency of NK cell precursors (NK-p) reactive with HSV-1-infected cells was 2- to 11-fold higher than that of NK-p reactive with mock-infected cells. The frequency of NK-p reactive with infected target cells lacking viral glycoprotein C or presenting an antigenically altered glycoprotein B was approximately twofold lower than that with wild-type virus-infected cells. Specificity analysis demonstrated that NK cells with a high statistical probability of being monoclonal were reactive with either glycoprotein B or C. These results provide the first evidence that cells with human NK activity possess clonal specificity for HSV-1-infected target cells.
