AB The development of naive dense CD4+ T cells from different mouse strains
toward Th1 cells, as monitored by measuring secondary IFN-gamma
production, was affected by TGF-beta 2 in a differential way. Th1 cell
development of naive CD4+ T cells from strains C57Bl/6, BALB/c, and NMRI
primed by immobilized anti-CD3 mAb was strongly inhibited in the
presence of TGF-beta 2. Even when the Th1 cell-inducer IL-12 was added,
the same effect of TGF-beta 2 was observed. In contrast, Th1 development
was substantially promoted by TGF-beta 2 with T cells from C3H/He and
CBA/J mice. Further analyses using CD4+ T cells from (C57Bl/6xCBA/J)F1
hybrids or DBA/1 mice showed that Th1 development was inhibited by
TGF-beta 2 if the T cells were activated by anti-CD3 mAb, but it was
enhanced upon costimulation with anti-CD28 mAb. Determination of primary
IL-2 production revealed that T cells from (C57Bl/6xCBA/J)F1 and DBA/1
mice produced low amounts of IL-2 following stimulation by anti-CD3 mAb
alone and comparatively high amounts after coactivation by anti-CD28
mAb. In the presence of TGF-beta 2, the production of IL-2 was
completely suppressed if such T cells were activated solely by anti-CD3
mAb, but it was only partially inhibited after costimulation by
anti-CD28 mAb. Furthermore, TGF-beta 2-promoted Th1 development of such
T cells was strongly inhibited after neutralization of endogenously
produced IL-2 and completely restored by the addition of human IL-2.
Thus, our results indicate that the TGF-beta 2-mediated stimulation of
Th1 cell development requires the presence of relatively high
concentrations of IL-2. Therefore, the opposing effect of TGF-beta 2 on
the Th1 cell development of naive CD4+ T cells from different mouse
strains appears to be the result of the variable potency of the
respective CD4+ T cells to produce IL-2 in the presence of TGF-beta 2.
