The extended substrate specificity of the human mast cell chymase reveals a serine protease with well-defined substrate recognition profile.

abstract：:The profile of cytokines produced by CD4 T cells is profoundly influenced by the presence of IL-12. Here we demonstrate that during re-stimulation of antigen-specific immune responses in vitro, antigen-primed lymph node cells from DBA/2 mice produced 3- to 30-fold more IL-12 than did cells from BALB/c mice, which are ...
