1 Antibody-mediated blockade of GPIbalpha or of its receptor, Mac-1 integrin, inhibited the secretion of PGE2, IL-1beta, and IL-6 in MDP + Tc CM-activated monocytes, whereas recombinant GPIbalpha protein increased PGE2 production by MDP-treated monocytes. Dinoprostone integrin subunit alpha M Homo sapiens
2 Antibody-mediated blockade of GPIbalpha or of its receptor, Mac-1 integrin, inhibited the secretion of PGE2, IL-1beta, and IL-6 in MDP + Tc CM-activated monocytes, whereas recombinant GPIbalpha protein increased PGE2 production by MDP-treated monocytes. Dinoprostone integrin subunit alpha M Homo sapiens
3 Our findings suggest that the production of PGE2 and proinflammatory cytokines by MDP-activated monocytes is mediated by cooperation between two signaling pathways: one delivered by MDP through NOD2 and a second through activation of Mac-1 by T cell-derived GPIbalpha. Dinoprostone integrin subunit alpha M Homo sapiens
