HSV-2 FRT CD4 T cell antigen and epitope discovery using culture-expanded TRM. (A) Screen of skin biopsy-derived TCL from subject 9149 against HSV-2 proteome in duplicate proliferation assay. Gene and short protein names of antigenic proteins are shown; negative control mock virus and positive control whole UV-killed HSV-2 and PHA at right. (B) Peptide epitope workup for cervix-derived TCL from subject 9149. OLP from HSV-2 gD (gene US6, 15AA long, left) or HSV-2 VP22 (gene UL49, 13 AA long, right) were arrayed in row (RP) and column (CP) pools with 1 μg/ml each peptide. Peptides from the intersection (UL6) or intersections (UL49) of reactive pools were re-assayed at 1 μg/ml at right of each diagram. APC were autologous irradiated PBMC. Colored dots are duplicate raw data and gray bar is mean.
