In order to establish the species cross-reactivity of the human neutrophil attractant/activation protein-1 (interleukin-8, NAP-1/IL-8) and find which experimental species are responsive to the human cytokine, blood polymorphonuclear leukocytes (PNMLs) were isolated from chicken, dog, goat, guinea-pig, monkey, mouse, pig, rabbit, and rat and their in vitro migration in response to this cytokine was investigated. PMNLs from all of the tested species migrated in response to recombinant human NAP-1/IL-8 (rhNAP-1/IL-8). The potency of rhNAP-1/IL-8 for the PMNLs of different species varied and was considerably lower than its potency for human cells. The morphological study combined with the leukocyte enumeration in the intradermal rhNAP-1/IL-8 injection sites established an in vivo proinflammatory potency of rhNAP-1/IL-8 for rabbit and rat that was comparable to the observed in vitro chemotactic potency of rhNAP-1/IL-8 for neutrophils of these species.
