Intracellular and surface distribution of CD9 in human eosinophils.


Expression of CD9 is a feature of both eosinophils and platelets. We have investigated the CD9 expression on resting and activated eosinophils with regard to possibly interacting platelets. Mixed leukocytes were obtained from the platelet-containing (PC) and platelet-depleted (PD) peripheral blood of healthy donors. A cell membrane permeabilization… (More)
