The role of adhesion molecules in antibody-dependent cell-mediated cytotoxicity (ADCC) of macrophages toward the extracellular parasite Schistosoma mansoni was investigated by using 1) a panel of blocking mAbs directed against adhesion molecules and 2) different soluble ligands as candidate inhibitors of ADCC. The results show that the beta2-integrin Mac-1(More)
A quantitative and kinetic study of the release of the hematopoietic cytokines IL-3, IL-5 and GM-CSF, the immunoregulatory cytokine IL-12 heterodimer (and its p40 subunit) and IL-13 by human peripheral blood mononuclear cells (PBMC) stimulated in vitro with the superantigen streptococcal pyrogenic (erythrogenic) exotoxin A (SPE A) from Streptococcus(More)
The anti-inflammatory effects of CI-1044 and of the other selective PDE4 inhibitors rolipram and cilomilast were investigated in Brown-Norway (BN) rats, against lipopolysaccharide-induced tumor necrosis factor alpha (TNFalpha) production in whole blood and antigen-induced lung eosinophilia. In vitro, CI-1044 inhibited TNFalpha production with an IC(50) of(More)
