Activation of cGAS-STING signaling pathway and accumulation reactive oxygen nitrogen species (RONS) are important issues facing the treatment rheumatoid arthritis (RA). Here, we report a biomimetic nano-Chinese medicine (HA-RM-Cel-BR) for RA immunotherapy based on STING inhibition celastrol (Cel) RONS clearance bilirubin (BR). HA-RM-Cel-BR is constructed by carrier-free self-assembly active ingredients Cel BR from traditional Chinese medicine, then camouflaged hyaluronic acid (HA)-modified red blood cell membranes (RM). prolongs circulation time through RM camouflage, targets inflamed joints HA modification, remodels joint immune microenvironment clearance. More importantly, shows excellent therapeutic effects rat model, significantly reduces hepatotoxicity associated with Cel. Our work provides new strategy ingredients.

α-Solanine (α-Sol) shows promise for pancreatic cancer (PC) treatment by inhibiting PC cell proliferation, migration, and invasion. However, its clinical application is hindered poor tumor targeting, significant toxicity, undesirable pharmacokinetics. To address these issues, this study developed a nanoparticle delivery system (PBSO NPs) using bovine serum albumin as carrier, with polyallylamine hydrochloride surface modification to enhance α-Sol delivery. PBSO NPs were characterized transmission electron microscopy, dynamic light scattering, size analyzers, Fourier-transform infrared spectroscopy. Their in vitro drug release profile cellular uptake capabilities evaluated. Furthermore, experiments conducted mouse cells (Panc02) investigate the effects of on Panc02 viability, invasion, apoptosis. Additionally, xenograft model was established vivo explore impact growth. This successfully favorable morphology physiological stability, capable enhancing uptake. In demonstrated that significantly inhibited invasion while promoting Moreover, enhanced inhibitory cells. further confirmed improved therapeutic efficacy against partially reducing toxicity. exhibited good biocompatibility. apoptosis, thereby suppressing progression PC. provides promising strategy treatment.
