In these culture conditions, a subset of T cells produced IL-10 (% IL-10+ T cells: mean±SE: 11±1, n=10), whereas a markedly lower proportion of cells produced IL-4 (% IL-4+ T cells: mean±SE: 2±0.4, n=10), in comparison to cells cultured in nonpolarizing conditions (Th0) (% IL-10+ T cells: mean±SE: 3±0.5; % IL-4+ T cells: mean±SE: 11±2, n=10) (Fig. 1A and B).
