title: Role of cytoskeletal elements in cytochalasin E-induced superoxide production by human polymorphonuclear leukocytes.
abstract: The release of superoxide anions from human polymorphonuclear leukocytes induced by cytochalasin E was greatly enhanced by the pretreatment of the cells either with deuterium oxide or with concanavalin A. Colchicine, vinblastine and cyclic AMP inhibited the release. Cytochalasins A and B also suppressed the superoxide release. These observations suggest the involvement of microfilament-microtubule system in the production and release of superoxide anions induced by cytochalasin E.
