stroke dmge Simir tther members in the MMP cogense cn brekdown cogengetin structuresin previous in vitro studies hs been shown to ceve proMMP to ctive MMP, which cn sccur foowing MMP.With regrd to this study, we fou tht PDGFR suppression significnty reduced MMP ctivity but not MMP. We sbserved tht the expression of MMPMMP were Osthole significnty decresed foowing PDGFR suppres sion.of these resuted in preservtion of the BBB integ rity. In , tken together, MMPs my be the direct down strem proteins of the PDGFR p pthwydirect meditors of BBB impirment foowing ICH. We hve discussed downstrem orchestrtors of PDGFR iuced BBB dmge.
We so wnted to investigte wht ws responsibe for the upstrem regu tion of PDGFR signing foowing ICH injury. Previ ous iterture hs uded to the notion tht ombin regutes the Lenalidomide expression of PDGF ough PR receptor fou in eothei ces.Therefore, in the present study, different mice modes were coucted to investigte the potenti retionship between ombinPDGF. First. in the utoogous rteri bood iuced ICH mode, we fou tht PDGF expres sion ws significnty downreguted foowing the deiv ery of hirudin, ombinspecific inhibitor. We so fou tht the effects of hirudin on BBB preservtion were reversed by exogenous PDGF injection. In the ombin injection mode, we first fou the increse of phosphoryted PDGFR eve s we s its downstrem signs, p MPKMMPs,the diminishmentGeneGenebnk ccession no.
