MALT1 inhibition does not affect regulatory T cell (Treg) development. Quantification of the percentage CD3+ CD4+ Foxp3+ cells at 24 days post-immunization (A) or at different time points after experimental autoimmune encephalomyelitis (EAE) induction (B). Percentage CD3+ CD4+ Foxp3+ cells from control and MALT1 knockout mice are included in panel (A). (C) Differentiation of naïve T cells into CD4+ Foxp3+ T cells at different time points in vitro. Data are depicted as mean ± SEM.
