| Research Abstract |
(1) We found that ligand-dependent RAGE signal was suppressed by cAMP-dependent signaling pathway, using mouse macrophage culture system.
(2) We showed that cAMP-dependent signal caused activation of MMP9 that accelerated shedding of membrane-bound form RAGE, which resulted in decrease of membrane-bound form RAGE and increase of soluble form RAGE.
(3) The mechanism of the suppression of ligand-dependent RAGE signal by cAMP-dependent signal was supposed that the acceleration of shedding of membrane-bound form RAGE via cAMP-dependent signal resulted in decrease of membrane-bound form RAGE functioning signal transducer and increase of soluble form RAGE functioning decoy receptor.
