Progress in Study of Low-Intensity Pulsed Ultrasound Acting on Inflammation-Related Signaling Pathways in Knee Osteoarthritis by OUYANG Hui, LIN Xingjin, WANG Jinying, SHEN Longbin, WANG Chengdong

“…The therapeutic mechanisms reviewed as following: 1) LIPUS can reduce the inflammatory response by enhancing the autophagic pathway of macrophages in the synovial membrane and inhibiting the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammatory vesicle pathway to reduce IL-1β production by macrophages; it can also acts through the classical wingless MMTV integration site family protein (Wnt)/β-linked protein signaling pathway on fibroblasts in the synovial membrane to inhibit synovial fibrosis. 2) LIPUS promotes chondrocyte production of extracellular matrix, regulates chondrocyte metabolism, and protects cartilage by inhibiting IL-1β -induced nuclear factor-activated B-cell κ light chain enhancer (NF-κB) signaling pathway and regulating mitogen-activated protein kinases (MAPKs) signaling pathway. 3) LIPUS protects cartilage by activating extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphatidylinositol 3-kinase-protein kinase B (PI3K-Akt) signaling pathways to promote MSCs proliferation and differentiation, and also promotes transforming growth factor-beta1 (TGF-β1) production by MSCs through the integral protein-target of rapamycin (mTOR) signaling pathway to promote cartilage formation. …”
