Prevention of carrageenan-induced pleurisy in mice by anti-CD30 ligand monoclonal antibody

CD30 ligand (CD30L) and its receptor CD30 are members of the tumor necrosis factor (TNF) and TNF receptor superfamilies that play a major role in inflammation and immune regulation. To gain insight into the in vivo role of CD30L/CD30 in inflammatory diseases, we have used carrageenan (CAR)-induced pleurisy in mice, a preclinical model of airway inflammation where type 1 proinflammatory cytokines such as interleukin (IL)-1 and TNF-α play a key pathogenic role. ta show that prophylactic treatment with anti-CD30L mAb markedly reduces both laboratory and histological signs of CAR-induced pleurisy. These data suggest involvement of CD30-mediated signals in acute immunoinflammatory pathways induced by CAR.
