Protective effect of hyaluronic acid on interleukin-1-induced deregulation of β1-integrin and insulin-like growth factor-I receptor signaling and collagen biosynthesis in cultured human chondrocytes

The mechanism of protective action of hyaluronic acid (HA) on collagen metabolism disturbances in tissues during inflammation is not known. Insulin-like growth factor-I (IGF-I) receptor and β1-integrin receptor signaling plays an important role in the regulation of collagen biosynthesis at both transcriptional and post-transcriptional levels. The present study was undertaken to evaluate the effect of IL-1β (inductor of experimental inflammation)...
