Chronic environmental exposure to polystyrene microplastics increases the risk of nonalcoholic fatty liver disease.

Microplastics (MPs), as the crucial environmental pollutants, can be easily transported into the human body and accumulate in the liver. However, current studies mainly focus on acute exposure to MPs, investigations on long-term interactions with MPs alone remain limited. Thereby, we examined noxious properties of MPs and selected the most common polystyrene (PS) MPs as the research object, including unmodified PS MPs (PS-MPs) and positive-charged PS MPs (PS-NH) at 10 mg/L employing oral drinking water methods in mice for six consecutive months in vivo.

Analysis of how melatonin-upregulated clock genes PER2 and CRY2 alleviate rheumatoid arthritis-associated interstitial lung disease.

Melatonin (Mel) serves as the central regulator for maintaining circadian rhythms and plays a crucial role not only in controlling the rhythmic clock, but also in several functional domains such as immunomodulation and anti-inflammation. In this study, we explored the clinical relevance of Mel and rheumatoid arthritis comorbid with interstitial lung disease (RA-ILD), and its potential therapeutic effects on arthropathy and pulmonary fibrosis (PF) in mice with collagen-induced arthritis (CIA). The results demonstrated that low serum levels of Mel were correlated with disease activity and severity of PF in RA-ILD patients.
