Cutting edge: in the absence of TGF-β signaling in T cells, fewer CD103+ regulatory T cells develop, but exuberant IFN-γ production renders mice more susceptible to helminth infection.

Abstract excerpt

Multiple factors control susceptibility of C57BL/6 mice to infection with the helminth Heligmosomoides polygyrus, including TGF-β signaling, which inhibits immunity in vivo. However, mice expressing a T cell-specific dominant-negative TGF-β receptor II (TGF-βRII DN) show dampened Th2 immunity and diminished resistance to infection. Interestingly, H. polygyrus-infected TGF-βRII DN mice show greater frequencies of...
