4.4 Interactions between cartilage and synovium 4.4.1 Interplay between cytokines released by chondrocytes and synovial cells When cartilage is damaged, chondrocytes release proteoglycan fragments, type II collagen fragments, and diverse injury-associated factors that synovial cell surface pattern recognition receptors (PRRs) can detect, prompting synovial hyperplasia and proinflammatory cytokine secretion (139)
They also downregulate the expression of TNF-, IL-1, IL-6, monocyte chemotactic protein 1, and TGF-1, effectively alleviating PF (Sherekar et al., 2024)
