TLR2-dependent recognition of Streptococcus suis is modulated by the presence of capsular polysaccharide which modifies macrophage responsiveness.

abstract：:Several cis-acting elements regulate the expression of germline transcripts of heavy chain constant region genes and their subsequent switch recombination. To study such elements in the murine gamma1 gene, we have utilized a transgenic approach. In this study we focused on a DNase I hypersensitive site (termed 'Site I...

Previously, we had shown that anergy can be induced in antigen-primed but not naive T cells. In this report, we found that in vitro primed T cells from IL-2R alpha-deficient mice were resistant to anergy induction in c...
