TFF3 and bacterial arthritis: In a previous study, we found that TFF peptides are absent in healthy articular cartilage, but in certain disease states, such as osteoarthritis (OA) or septic arthritis, the TFF family member TFF3 supports catabolic functions and links inflammation to tissue remodeling processes, which distinguishes TFF3 as a potential factor in the pathogenesis of OA [19].
