 AB    The lymphocyte subset expressing the gamma delta T cell receptor is
       increased in several infectious diseases including HIV infection. In
       this study the expression on gamma delta lymphocytes of the T cell
       activation markers CD25, HLA-DR and CD38, as well as the two isoforms of
       CD45, namely CD45RA and CD45RO, was determined in the peripheral blood
       of 56 HIV-infected intravenous drug users and 34 HIV-seronegative blood
       donors by two-colour flow cytometry. The percentage of gamma delta
       lymphocytes expressing HLA-DR and CD38 was higher than those in
       HIV-seronegative controls (P < 0.001 and P < 0.0001, respectively).
       Furthermore the HLA-DR+gamma delta+ lymphocytes correlated inversely
       with CD4+ T lymphocyte absolute count (P < 0.02 for both). The levels of
       gamma delta lymphocytes expressing CD25, CD45RA and CD45RO were similar
       to those in HIV-seronegative controls. Activated gamma delta lymphocytes
       may play a role in the HIV disease process and could provide a useful
       marker for disease progression.
