- 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.
