Biomimetic polymersomal nanoreactors for hepatocyte-directed detoxification in drug-induced liver injury.

ABSTRACT: Drug-induced liver injury (DILI) is a major clinical concern associated with drug toxicity, primarily characterized by hepatocyte damage driven by oxidative stress and inflammation. Excessive accumulation of reactive oxygen species (ROS) and pro-inflammatory cytokines exacerbates liver injury, necessitating effective therapeutic interventions. While natural antioxidant enzymes exhibit high catalytic activity and specificity in ROS scavenging, their clinical use is limited by poor stability in circulation and limited cellular uptake. To address these challenges, we developed antioxidant polymersomal nanoreactors (CS@PS) for the targeted co-delivery of catalase (CAT) and superoxide dismutase (SOD). CS@PS functions as a cascade system, efficiently neutralizing ROS and mitigating inflammation
