For instance, elevated 4-HNE in synovial fluid has been reported in multiple studies, but significant variations in detection methods and patient stratification such as disease stage and inflammation degree between studies mean the strength of evidence for 4-HNE as a driver of OA inflammation amplification still requires cautious interpretation

Moreover, ALA exerts antioxidant effects via a dual mechanism: (i) rapid redox-cycling between its disulfide (ALA) and dihydrolipoate (DHLA) forms, which directly quenches ROS without transcriptional activation, and (ii) secondary upregulation of the Nrf2 pathway and suppression of NF-B nuclear translocation (Ghibu et al., 2009)
