6‐Shogaol inhibits chondrocytes’ innate immune responses and cathepsin‐<scp>K</scp> activity

Abstract

6-S blocked TLR4-mediated innate immune responses and MMP induction in chondrocytes. These results, together with GDs-mediated cathepsin-K inhibition, suggest the potential for GDs use against cartilage and bone degradation. Therefore, considering that clinical trials involving oral administration of ginger achieved relevant nontoxic GDs serum concentrations, we suggest that a ginger-supplemented diet might reduce OA symptoms.
