Acute lung injury (ALI), one of the most severe respiratory system diseases, is prevalent worldwide. Annexin A1 (AnxA1) an important member annexin superfamily, known for its wide range physiological functions. However, potential protective effect against lipopolysaccharide (LPS)-induced ALI remains unclear. Mice were divided into four groups: Sham, LPS + vehicle, 0.1 μg AnxA1, and 0.5 AnxA1. Lung was assessed through histopathology, pulmonary wet-to-dry (W/D) ratio, cell counting bronchoalveolar lavage fluid (BALF), oxidative stress analysis, noninvasive function testing. Gene protein expression levels measured using RT-PCR, ELISA, western blot analysis. AnxA1 alleviated LPS-induced by protecting tissue from damage, reducing wet/dry weight improving impaired function. Interestingly, administration found to repress infiltration inflammatory cells decreasing total count, neutrophils, concentrations in (BALF). mitigated response lowering IL-1β, IL-6, TNF-α BALF mice. Additionally, attenuated tissues mice restoring activity catalase (CAT), SOD, glutathione (GSH) but malondialdehyde (MDA). We also that suppressed activation NLRP3 signaling pathway. Mechanistically, activated Nrf2/HO-1 pathway while preventing NF-κB. Collectively, these findings suggest alleviates might be a promising novel therapeutic agent ALI.

Background Pneumonia is a serious respiratory illness that impacts the lungs, leading to inflammation and fluid accumulation in alveoli, tiny air sacs essential for gas exchange. Mycoplasma pneumonia severe infection caused by atypical bacterium pneumoniae (MP). Purpose The primary objective of this work explore therapeutic effects ferulic acid against MP-infected an experimental mice model. Methods In work, BALB/c were subjected 100 µL MP challenge via nasal drips trigger pneumonia. then administered 50 mg/kg 3 days. After experimentation, lung weight, myeloperoxidase (MPO), nitric oxide (NO) concentrations assessed. inflammatory cytokines oxidative stress biomarkers analyzed using appropriate diagnostic kits. total cell count bronchoalveolar lavage (BAL) deoxyribonucleic (DNA) concentration lungs assessed mice. histopathology examination was conducted evaluate histological abnormalities. Results administration significantly decreased MPO, NO Ferulic treatment resulted diminution malondialdehyde (MDA) enhancement glutathione (GSH) superoxide dismutase (SOD) concentrations. diminished marker MP-challenged Furthermore, reduced DNA content counts addition, outcomes indicated significant reduction alveolar damage with Conclusion findings confirm salutary properties Consequently, may serve as effective drug candidate treatment.

Microcystin-LR (MC-LR) a cyclic toxin produced by cyanobacterial species is known to exert detrimental effects on various organs, including lung. Several investigators demonstrated that MC-LR exerts pulmonary toxicity, but the underlying mechanisms remain unclear. This study aimed investigate whether exposure MC-LR-induced lung inflammation and examine mechanisms. Thirty specific pathogen-free (SPF) male mice were allocated into control treatment groups. Mice intraperitoneally injected with physiological saline or (20 μg/kg) daily for total of 21 days. Our findings indicated MC-LR-produced histopathological changes in tissue, thickening alveolar walls inflammatory infiltration. was found upregulate mRNA expression levels pro-inflammatory cytokines TNFα, IL-6, IL-1β, IL-18. Further, significantly elevated proteins associated NF-κB/NLRP3 pathway p-NF-κB, NLRP3, Caspase-1, ASC. The activation further promoted release cytokine IL-1β cleavage pyroptosis-associated GSDMD protein. These indicate may induce promoting cell pyroptosis via pathway.
