 AB    We have shown previously that IL-2-activated splenocytes can inhibit the
       growth of Candida albicans hyphae in vitro. Herein we demonstrate that
       plastic nonadherent lymphocytes that are CD8+ mediate the antifungal
       activity. Enrichment for CD8+ cells markedly enhanced the antifungal
       activity of the IL-2-activated lymphocyte population for C. albicans and
       the cytotoxic activity of the lymphocytes for an NK-resistant cell line.
       Depletion of CD8+ cells reduced the lymphocyte population's antifungal
       activity and cytotoxic activity for the NK-resistant cell line.
       Enrichment for NK1.1+ cells markedly reduced the antifungal activity of
       the lymphocyte population for C. albicans and increased the cytotoxic
       activity of the lymphocytes for an NK-sensitive cell line. Depletion of
       NK1.1+ cells increased the lymphocyte population's antifungal activity
       and cytotoxic activity for the NK-resistant cell line. Generation of the
       antifungal lymphocytes in culture required IL-2 and was not replaced
       with IFN-gamma. These data show that IL-2-activated CD8+ T lymphocytes
       exert the greatest amount of antifungal effect against the hyphal form
       of C. albicans, whereas IL-2- or IFN-gamma-activated NK cells have
       little or no effect against the hyphae.
