Eleven cloned and uncloned measles virus-specific T cell lines were generated from peripheral blood lymphocytes obtained from a patient with multiple sclerosis and were assayed for measles polypeptide specificity. Three clones reacted specifically with the fusion (F) protein and one recognized the hemagglutinin (HA). Two reacted with whole virus but not with any of the purified proteins. Five cell lines proliferated in response to multiple measles polypeptides. The addition of anti-HA or anti-F monoclonal antibodies to two of the multispecific cell lines each resulted in partial suppression of the proliferative response to whole virus by the cell lines. Two of the three F-reactive clones recognized antigen in association with a subgroup of HLA-DR4; the third responded to F only in the presence of autologous antigen-presenting cells. Of the two clones that reacted only with whole virus, one was restricted to DP3 and one to autologous cells. The HA-specific clone was DP3 restricted. Several cell lines recognized multiple measles polypeptides in association with a single HLA antigen. Recognition of individual measles polypeptides does not segregate with specific genetic restriction elements.
