Enhanced suppression of polyclonal CD8+25+ regulatory T cells via exosomal arming of antigen-specific peptide/MHC complexes.

abstract：:Endotoxin tolerance is characterized by attenuated macrophage activation to subsequent LPS challenge and can be reversed through nonspecific protein kinase C (PKC) activation, and activation by LPS within naïve cells requires the activation of the cell surface receptors CD14 and TLR4 on lipid rafts.
