- Abstract
The integrin CD11b/CD18 promotes leukocyte extravasation during inflammation. Filamentous hemagglutinin (FHA) of Bordetella pertussis binds to CD11b/CD18, raising the possibility that peptides derived from FHA might inhibit leukocyte migration. The Arg-Gly-Asp (RGD) sequence of FHA has been suggested to modulate binding of ligands to CD11b/CD18. Peptides derived from this region inhibited adherence and transendothelial migration of neutrophils in vitro and prevented recruitment of leukocytes into the cerebrospinal fluid in an experimental model of meningitis in rabbits. The mechanism of the antiinflammatory effect may involve modulation of the activity of CD11b/CD18 through peptide interaction with the leukocyte response integrinlintegrin-associated protein complex.
