PPD-specific proliferative response in humans. I. Analysis of PPD-specific proliferative cells from tuberculous pleurisy patients and healthy controls with monoclonal antibodies specific for human T subsets. 1982

Y Okubo, and S Kusama, and A Yano

Peripheral mononuclear cells (PBL) from tuberculin reaction (TR)-negative tuberculous pleurisy patients proliferated poorly with PPD, while the cells of pleural effusion from these patients showed a proliferative response to PPD as well as did the healthy control PBL. Surface antigens of peripheral blood and pleural effusion were examined by using monoclonal antibodies. The Leu 1-positive cell population can be divided into four groups, namely (1) Leu 1+, Leu2a+, Leu 3a+, (2) Leu 1+, Leu 2a+, Leu 3a-, (3) Leu 1+, Leu 2a-, Leu3a+, and (4) Leu 1+, Leu 2a-, Leu 3a- cell populations. Results of analysis of surface antigens of PPD-specific proliferative cells in peripheral blood and pleural effusion from tuberculous pleurisy patients as well as healthy controls indicate that the PPD-specific proliferative response is mediated by Leu 1+, Leu 2a-, Leu 3a+ cells and Leu 1+, Leu 2a-, Leu3a- cells.

D013601 T-Lymphocytes Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
