Antigen localization within the splenic marginal zone restores humoral immune response and IgG class switch in complement C4-deficient mice.

abstract：:Evidence from several different experimental systems suggests that regulatory cells specific for self-antigens exist in the normal immune repertoire, and that these cells are necessary for maintenance of self-tolerance and prevention of autoimmune disease. We attempted to demonstrate the existence of regulatory cells ...

abstract：:Toll-like receptors (TLRs) recognize a variety of microbial products and induce defense responses. Pathogen sensing by TLRs occurs either on the cell surface or in endolysosomes. TLR-dependent responses are greatly influenced by the site of pathogen sensing. TLR heterodimers TLR1/TLR2 and TLR2/TLR6 recognize tri- or d...
