Gamma delta T cell receptor-bearing lymphocytes during Epstein-Barr virus infection.

Lymphocytes bearing gamma delta T cell receptors (TCR) constitute a minor subpopulation of human peripheral blood lymphocytes. Their role and function during microbial infections are largely unknown. In 10 patients with Epstein-Barr virus-induced infectious mononucleosis, the gamma delta TCR-expressing T cell population expanded during the acute phase.
