Abstract

In the air pouch-type allergic inflammation model in rats, leukocytes collected from the pouch fluid 4 h after the antigen challenge produced proteinaceous chemotactic factors for neutrophils. The leukocytes from the immunized rats produced significantly higher amount of the chemotactic factors than that from the non-immunized rats. The major chemotactic factor, leukocyte-derived neutrophil chemotactic factor (LDNCF)-2, was purified and found to be identical with rat macrophage inflammatory protein (MIP)-2 by N-terminal amino acid sequence analysis. Expression of MIP-2 mRNA was higher in the leukocytes from the immunized rats than that from the non-immunized rats. Possible roles of LDNCF-2 (MIP-2) in neutrophil infiltration in the allergic inflammation is discussed.
