Developing low-toxicity, high-efficacy, and fast-acting strategies to manage acute liver injury (ALI) is critical due its rapid progression potential for severe outcomes. Curcumin (CUR) has shown promise in ALI therapy ability modulate the inflammatory microenvironment by scavenging reactive oxygen species (ROS). Nevertheless, CUR highly hydrophobic limiting bioavailability effective vivo transport, which hinders further application. In this study, we developed an microenvironment-targeted drug delivery system covalently coupling human serum albumin (HSA) with ROS-sensitive thioketal linkers loading it form nanoparticles (HSA-TK/CUR). These were then coated a macrophage membrane (CM@HSA-TK/CUR), resulting negatively charged spherical particles (≈ −23.26 mV) average particle size of around 165 nm. ROS responsiveness was confirmed through release assays enhanced depletion demonstrated Diacetyldichlorofluorescein (DCFH-DA) detection experiments. CM@HSA-TK/CUR treatment resulted 94.7% reduction levels cells. addition, cellular uptake distribution experiments that camouflaging HSA-TK/CUR membranes significantly targeting microenvironment. The findings revealed rapidly accumulated injured within 6 h, inhibited production pro-inflammatory factors (IL-1β, IL-6, TNF-α), shifted polarization from M1 M2 vivo, protected hepatocytes oxidative stress-associated cell death, attenuating response mice. conclusion, excellent treating mice ALI.

In intensive care units, acute lung injury (ALI) is a syndrome that frequently encountered. It associated with high rate of morbidity and mortality. Despite the extensive research conducted by medical community on its treatment, no specific effective drugs have been identified. Quercetin natural flavonoid many biological activities pharmacological effects. Research indicates can modulate various targets signaling pathways, inhibiting oxidative stress, inflammatory responses, ferroptosis, apoptosis, fibrosis, bacterial viral infections in ALI. This regulation suggests potential therapeutic application for condition. Currently, there comprehensive review addressing treatment paper begins classification ALI, followed detailed summary mechanisms through which may treat ALI to evaluate as novel option.
