WebPhosphodiesterase (PDE)-4 inhibitors, β2-adrenoceptor agonists, and E-series prostaglandins also attenuate the induction of the TNF-α gene in human monocytes in response to bacterial LPS. The mechanism of action of cAMP is unclear, but in the mouse, is believed to involve the generation of the anti-inflammatory cytokine, interleukin-10 (IL-10). WebUsing inhibitor and dominant-negative constructs, we demonstrated that phosphatidylinositol 3-kinase (PI3K) was a key downstream effector of R-Ras in this pathway. Conclusions—OxPAPC, POVPC, and PEIPC induce a cAMP/R-Ras/PI3K signaling pathway that contributes to monocyte/endothelial cell adhesion and potentially …
WebSep 26, 2014 · Monocytes are generally considered as an intermediate developmental stage between bone marrow precursors and tissue macrophages . However, circulating monocytes have important effector functions, both during homeostasis through patrol and repair functions and during infections by exerting inflammatory effects . WebFeb 1, 1997 · Two cAMP analogs, 8- and 2- [ (4-bromo-2,3-dioxobutyl) thio]adenosine 3′,5′-cyclic monophosphate (8- and 2-BDB-TcAMP) have been used in probing the catalytic site of recombinant monocyte cAMP-specific phosphodiesterase (PDE4a). 2-BDB-TcAMP is a reversible and competitive inhibitor (K = 5.5 μmol/L) of cAMP hydrolysis by PDE4a. 8 …
