pubmed:abstractText |
Peripheral blood leukocytes from ARC and AIDS patients were analyzed following phytohemagglutinin- and pokeweed mitogen-induced lymphocyte transformation by dual-color flow cytometry using monoclonal antibodies that identify developmental (HLA-DR) and functional (Leu8) subsets of T cells and monocytes. Significant decreases in both the suppressor regulating helper T subset (Leu3+ Leu8+) and the reciprocal inducer helper T subset (Leu3+ Leu8-) responsible for inducing differentiation of B cells were observed. Simultaneously, the percentages of the effector suppressor T cells and the precursor suppressor T cells were increased, both of which were required for generation of suppression of cell-mediated immunity. There was also a progressive selection of Ia+ cells bearing the Leu2 (Ts) markers and a concurrent reduction of the percentage of antigen-presenting monocytes and activated helper T cells. These results suggest that the functional deficiencies in AIDS may be caused by defects in T-cell activation as well as antigen presentation by monocytes. Isoprinosine induced an increase in both regulator Th (Leu3+ Leu8+) and inducer Th (Leu3+ Leu8+) subsets of helper T cells while potentiating the expression of Ia antigen on helper T cells and monocytes during mitogen-driven DNA synthesis. These events initiated a cascade of cellular interactions leading to partial restoration of cell-mediated immune responses. These interferences with the defective helper/suppressor regulatory pathways may have important therapeutic implications.
