Abstract
Osteoarthritis (OA) is a socially significant age-associated disease, for the treatment of which a search for new effective drugs is underway. The development of OA correlates with the development of the aging-associated secretory chondrocyte phenotype (SASP). The purpose of the review is to analyze the pool of signaling molecules that form SASP of chondrocytes in OA and substantiate the possibility of peptide chondroprotection. It has been established that SASP of chondrocytes is characterized by a decrease in the synthesis of sirtuins, impaired remodeling of the extracellular matrix, and activation of cytokine production. Sigumir, a polypeptide complex of cartilage and bone tissues of young animals, and the AED tripeptide (Kartalax) have shown high efficacy in animal models of OA and oral administration in patients with OA of older age groups. These peptide substances regulate the synthesis of proapoptotic and proliferotropic molecules that form the SASP of chondrocytes.
