The integrin α4β1 is expressed on a wide variety of peripheral leukocytes, and functions in recruitment of these cells to sites of inflammaiton. We infected august (AUG) rats with the helminth parasite Nippostrongylus brasiliensis and later used leukocytes from the peritoneum of the sensitized animals and antibodies against α4β1 integrin to localize that adhesion molecule on the cell surfaces after antigen challenge. We found that after antigen challenge, eosinophils, monocytes, and small lymphocytes, but not mast cells, expressed α4β1 integrin if the animals had been previously infected, but cells from uninfected animals did not show expression of this molecule. Our study describes a novel protocol for immunohistochemical analysis of rat eosinophils.
