title: Characterization of mouse peritoneal exudate and associated leukocyte adherence inhibitory activity after intraperitoneal injection of either Bordetella pertussis or Corynebacterium parvum vaccines.
abstract: Bordetella pertussis and Corynebacterium parvum are commonly used immunopotentiating agents. To explore the inflammatory environment induced by these agents, the peritoneal exudate response in mice following intraperitoneal injection of B. pertussis (PV) and C. parvum (CV) vaccines was investigated. The PV-induced exudate isolated by lavage was characterized by an early neutrophil influx followed by enhanced accumulation of mononuclear cells and fluid protein. The CV exudate was principally mononuclear in nature and displayed fewer numbers of cells and less fluid protein. Both vaccines also enhanced the leukocyte adherence inhibitory activity (LAIA) of peritoneal fluid as measured in vitro. The development of exudate LAIA was T lymphocyte independent. A similar LAIA was demonstrated in nonimmune mouse plasma and serum. Exudate fluid and serum LAIA were heat stable and trypsin sensitive. These studies suggest that significant differences exist in the composition of the local tissue environment following PV and CV injection and that exudate LAIA is serum derived. Further studies in this direction should result in a better understanding of the ways in which inflammatory cells and fluid substances affect lymphocyte-macrophage interaction subsequent to adjuvant administration.
