 AB    Human T cells reactive with mycobacterial antigens are generally
       considered to correlate with a Th1 cytokine profile. Our data show that,
       in addition, Th0 and Th2 clones develop in bulk culture with appropriate
       antigen-presenting cells before cloning. CD4+ blasts activated by
       mycobacterial antigens were cloned, and their mRNA patterns for the
       interleukins (IL) IL-2, IL-4, IL-5, IL-6, and IL-10 and gamma interferon
       were characterized by reverse-transcribed PCR. Nonadherent,
       nonrosetting, enriched peripheral blood mononuclear cells promoted
       development of Th0; after further depletion of monocytes and natural
       killer cells, Th2 clones were also found. Epstein-Barr virus-transformed
       B cells, with specificity for the stimulating antigen, increased the
       proportion of Th2 clones.
