Priming mechanisms and induction of heat shock proteins in human polymorphonuclear granulocytes induced by eicosanoids and cytokines.
Priming of human polymorphonuclear granulocytes (PMNs) with cytokines (IL-3, IL-6, TNF-alpha) followed by a subsequent stimulation (FMLP) led to an enhanced polymerization of actin and GTPase-activity which correlated to a loss of ras immunoreactivity and an increased expression of Rab proteins. Furthermore TNF-alpha and 12-HETE induced the heat shock proteins (hsp 70 family) in PMNs as was demonstrated by metabolic radiolabeling and Western blotting (anti-hsp 72). This activation of the stress response exerted a protective function towards a subsequent lytic attack by a bacterial cytolysin (leukocidin).
