School of Medicine, Boston, Massachusetts, USA The anti-tumor agent, Taxol, is a potent LPS mimetic in murine macrophages, an activity that is dissociable from its well-characterized anti-mitotic activity which is mediated by microtubule hyperstabilization. A photoactivatable Taxol analog was used to identify components of a putative, shared LPS signaling apparatus in murine macrophage membranes. We report here that CD18, the ß chain of the ß2-integrin, Mac-1, represents a major Taxol binding protein in murine macrophages.
