PDGF-B may contribute to mesangioproliferative changes and is overexpressed in MsPGN. Recently, small interfering RNAs (siRNAs) have been widely used for gene silencing effects in experimental models of renal diseases. Nanoparticle-based therapeutics are preferred for reasons such as increasing therapeutic efficacy and reducing toxic effects caused by high doses. The distribution of nanoparticles to the kidney is a significant advantage in siRNA delivery. The aim of this study was to investigate the efficacy of chitosan/siRNA nanoplexes in silencing of PDGF-B and PDGFR-beta genes in kidney and to decrease mesangial cell proliferation and matrix accumulation in MsPGN model induced by anti-Thy-1.1 antibody. The therapeutic effects of chitosan/siPDGF-B + siPDGFR-beta nanoplexes in glomerulonephritic rats were studied by molecular, biochemical, and histopathologic evaluations. Chitosan/siPDGF-B + siPDGFR-beta nanoplexes markedly reduced PDGF-B and PDGFR-beta mRNA and protein expressions in experimental MsPGN model. Histopathologic examination results showed that the silencing of PDGF-B and its receptor PDGFR-beta led to reduction in mesangial cell proliferation and matrix accumulation. The use of chitosan/siPDGF-B + siPDGFR-beta nanoplexes for silencing the PDGF-B pathway in MsPGN can be considered as a new effective therapeutic strategy.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/68529</dc:identifier> <dc:identifier>oai:zenodo.org:68529</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>EXPERIMENTAL AND MOLECULAR PATHOLOGY 110</dc:source> <dc:title>The effectiveness of chitosan-mediated silencing of PDGF-B and PDGFR-beta in the mesangial proliferative glomerulonephritis therapy</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
