Strength of T cell receptor (TCR) signaling, coreceptors, costimulation, antigen-presenting cell type, and cytokines all play crucial roles in determining the efficiency with which type 2 T lymphocytes (Th2, Tc2) develop from uncommitted precursors. To investigate in vivo regulatory mechanisms that control the population of type 2 T cells and disease(More)
Signaling by the IL-4 receptor alpha-chain (IL-4Ralpha) is a key determinant of the development of the Th2 lineage of effector T cells. Studies performed in tissue culture cell lines have indicated that tyrosines of the IL-4Ralpha cytoplasmic tail are necessary for the induction of Stat6, a transcription factor required for Th2 differentiation.(More)
