title: Specific plasma cell accumulation in antigen-induced chronic inflammation in the guinea pig peritoneal cavity.
abstract: Specificity of plasmacellular infiltration was studied using a guinea pig peritoneal inflammation model. Acute and chronic inflammations were induced by repeated injections of either of two non-crossreacting antigens (DNP-BSA and PPD). With an enzyme-immunohistochemical sandwich procedure allowing quantitation of DNP-BSA-specific plasma cells, specificity of plasmacellular infiltration could be demonstrated. DNP-BSA-specific antibody-forming cells were found not to enter inflammatory reactions elicited by PPD. Our data support the hypothesis that virtually all plasma cells in a chronic inflammatory exudate release antibodies specific for antigens that are locally available, and that such antigens are likely to play a central role in the perpetuation of chronicity.
