Abstract

Osteoarthritis (OA) is a degenerative joint disease, in which low-grade inflammation plays an important role at the initiating step. Low-doses of LPS-induced inflammation in the plasma activate chondrocytes and promote the secretion proinflammatory cytokines, leading to secondary inflammation. Blocking OA­associated TLR activation is a promising strategy for the development of suitable therapies. Here, we want to find some bacteria-derived peptides that can block TLR signaling in chondrocytes more efficiently. Based on previous studies, we screened 12 TIR domain-derived peptides for their effects on NF-кB activation induced by LPS, IL-1β or TNF-α in murine ATDC-5 cells. We evaluated their effects on LPS-induced cytokine expression and secretion. Among them, two bacteria-derived peptides, TcpC-DD and TcpB-DD, showed the most potent inhibitory activities. In comparison with TcpB-DD, TcpC-DD exhibited broader TLR-inhibitory specificity during inflammation in chondrocytes. Furthermore, both TcpC-DD and TcpB-DD displayed strong inhibition of LPS- and IL-1β-induced catabolic reactions in chondrocytes. However, only TcpC-DD exhibited obvious suppression of TNF-α-induced catabolism. In conclusion, we identified two novel inhibitory peptides that modulate catabolism in chondrocytes and innate immune responses, and these peptides could be used to develop novel therapeutic strategies for OA.

Figure S1. Effects of TIR domain-derived decoy peptides on TNF-α induced mRNA expression. ATDC-5 cells were pretreated with peptides at 20 µM for 30 min and then stimulated with TNF-α at 10 ng/ml for 1 h. Next, cytoplasmic mRNA expression of TNF-α (A), IL-1β (B), IFN-β (C) and IL-6 (D) were measured and normalized to the expression of GAPDH. The results represent the mean values from triplicate experiments. Significant differences, compared to the TB-0 group, are indicated by asterisks (*P < 0.05, Student’s t-test). Figure S2. TcpC-DD inhibited TNF-α-induced cytokine secretion. ATDC-5 cells were transfected with the siRNA against MyD88 for 24h, then were treated with peptides at 20 µM for 30 min and then stimulated with TNF-α at 10 ng/ml for 24 h. Supernatants were collected and analyzed for IL-1β (A), IFN-β (B), and IL-6 (C) by ELISA. IL-1β was detected in cell lysates. The results represent the mean values from triplicate experiments. Significant differences, compared to the TB-0 group, are indicated by asterisks (*P < 0.05, Student’s t-test). (DOCX 87 KB)
