It has previously been shown that T cells specific for the triggering virus infiltrate the eye of patients with herpes simplex virus type 1 (HSV-1)-induced acute retinal necrosis (ARN). The T cells were mainly directed against 0.67-0.73 HSV-1 map region encoded antigens. The fine specificities of genetically different T cell clones (TCC), obtained from affected eyes of 3 patients with HSV-induced ARN and reactive toward this genomic region of HSV-1, were analyzed with recombinant HSV viruses and synthetic peptides. For 1 patient, the HSV-1 UL46 gene encoded tegument protein VP11/12 was identified as the target antigen. Two separate CD4(+) T cell epitopes were defined in VP11/12, TCC from the other 2 patients recognized the HSV-1 UL47 gene encoded tegument protein VP13/14. Two separate CD4(+) VP13/14 T cell epitopes were identified in these patients. Analysis of the data indicates that HSV-1 VP11/12 and VP13/14 are major target antigens for T cells obtained from vitreous fluid samples of the HSV-induced ARN patients studied.
