Malt1-deficiency prolongs MHC-mismatched skin graft survival. (A) To evaluate the role of TCR signaling mediated via Malt1 in alloresponses, recipient Malt1-ko and wild-type (Wt) B6 mice received a MHC-mismatched B6D2 skin allograft. As a comparison group, Wt mice were treated with cyclosporine A (CsA) i.p. daily after transplantation. (B) Graft survival. Graft draining lymph nodes (dLN) were harvested at rejection and analyzed by flow cytometry. (C,D) Frequency of CD4+ and CD8+ T cells, respectively. (E,F) Mean fluorescence intensity (MFI) of CD44 on the surface of CD4+ and CD8+ T cells, respectively. (G–L) Detection of intracellular cytokines after brief in vitro restimulation. (G,J) IFN-γ, (H,K) IL-2, (I,L) IL-17; in CD4+ and CD8+ T cells, respectively. n = 5 mice/group. MST, median survival time.
