Skewing of the T-cell receptor repertoire of CD8+ T
cells has been shown in some persistent infections with viruses, such
as human immunodeficiency virus, simian immunodeficiency virus, and Epstein-Barr virus. We have demonstrated that similar distortions also
occur in nonpersistent measles virus infection. In addition, two of
four children immunized with live, attenuated measles virus showed
larger and more persistent CD8+ T-cell expansions than
their naturally infected counterparts. The expanded lymphocyte
populations were monoclonal or oligoclonal and lysed target cells
infected with recombinant vaccinia virus expressing measles virus
protein. These results demonstrate that the expansions of
CD8+ T lymphocytes are antigen driven.
