Human atopen-specific types 1 and 2 T helper cell clones.
J Immunol. 1991 Nov 01; 147(9):2942-9.JI

Abstract

Eight representative T lymphocyte clones (TLC) randomly selected from previously described panels of CD4+ housedust mite Dermatophagoides pteronyssinus (Dp)-specific TLC from atopic and nonatopic donors were studied in more detail in a comparative investigation. The TLC from the atopic donors closely resembled murine type 2 Th (Th2) cells by secreting substantial IL-4, IL-5, IL-6, TNF-alpha, and granulocyte-macrophage (GM)-CSF, minimal IFN-gamma, and relatively little IL-2. In contrast, the nonatopic's TLC resembled murine type 1 Th (TH1) cells by secreting substantial IFN-gamma, IL-2, TNF-alpha, and GM-CSF, no IL-4, and little IL-5. A difference with murine Th1 cells was their additional secretion of IL-6. These cytokine profiles were consistent upon stimulation via different activation pathways including stimulation with specific Dp Ag, mitogenic lectins, and antibodies to CD2, CD3, or CD28. The observed differences in IL-2 secretion, however, were most evident upon stimulation with anti-CD28. If TLC cells were cultured with highly purified B cells and stimulated with anti-CD3 in the absence of exogenous IL-4, IgE synthesis was induced only in cultures with the atopics' Th2 clones, which could be completely abrogated by anti-IL-4. The mere presence of exogenous rIL-4, however, did not result in IgE synthesis, nor did unstimulated TLC cells alone. But if unstimulated TLC cells (that proved not to secrete detectable amounts of cytokines) were added together with rIL-4, again IgE synthesis was induced only in cultures with the atopics' Th2 clones, suggesting the involvement of an additional, as yet unidentified accessory helper function of the atopics' Th2 clones for IgE induction. Unstimulated Th2 clones showed a significantly higher expression of CD28 than the Th1 clones, but three days after stimulation, CD28 expression was elevated to comparable levels on both subsets. When added to B cells at this time point, together with rIL-4 and anti-IFN-gamma, still only the atopics' Th2 clones supported IgE synthesis, arguing against a role for CD28 in this accessory helper function. Whereas the atopics' Th2 clones were excellent helper cells for IgE induction, a unique property of the nonatopic's Th1 clones was their cytolytic activity toward autologous APC which could be induced by specific Dp Ag and by anti-CD3. The present data provide clear evidence for the existence of Th1 and Th2 cells in man.
