Class II major histocompatibility complex molecule expression on murine eosinophils activated in vivo by Brugia malayi.

abstract：:C-reactive protein (CRP) has long been known to appear in the sera of individuals with inflammatory processes, but its role in host defense against bacterial infection is unclear. We have recently demonstrated that CRP in the presence of the classical complement pathway markedly enhances the opsonization of Streptococ...
