Short-term exposures to PM2.5, PM2.5 chemical components, and antenatal depression: Exploring the mediating roles of gut microbiota and fecal short-chain fatty acids

PM2.5 and its chemical components increase health risks are associated with depression gut microbiota. However, there is still limited evidence on whether microbiota short-chain fatty acids (SCFAs) mediate the association between PM2.5, components, antenatal depression. The purpose of this study was to investigate mediating role maternal in correlations short-term exposure Demographic information stool samples were collected from 75 pregnant women their third trimester. Their measured. Participants divided into non-antenatal group or according cut-off 10 points Edinburgh Postnatal Depression Scale (EPDS). analyzed using 16 S rRNA-V3/V4 gene sequence, concentration calculated Tracking Air Pollution China (TAP) database. Gas chromatography–mass spectrometry used analyze SCFAs samples. In order assess effects SCFAs, mediation models utilized. There significant differences microbial composition concentrations group. positively EPDS scores negatively genera Enterococcus Enterobacter.

Chitosan Nanoparticle-Encapsulated Cordyceps militaris Grown on Germinated Rhynchosia nulubilis Reduces Type II Alveolar Epithelial Cell Apoptosis in PM2.5-Induced Lung Injury

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(3), P. 1105 - 1105

Published: Jan. 27, 2025

Chitosan nanoparticles (CNPs) were synthesized in this study to enhance the limited bioactivity and stability of Cordyceps militaris grown on germinated Rhynchosia nulubilis (GRC) effectively deliver it target tissues. Under optimized conditions, stable encapsulation GRC was achieved by setting chitosan (CHI)-to-tripolyphosphate (TPP) ratio 4:1 adjusting pH TPP 2, resulting a zeta potential +22.77 mV, which indicated excellent stability. As concentration increased, efficiency decreased, whereas loading increased. Fourier-transform infrared (FT-IR) spectroscopy revealed shifts amide I II bands CHI from 1659 1578 1639 cm⁻1, indicating hydrogen bonding successful encapsulated with CNPs (GCN). X-ray diffraction (XRD) examination transition crystalline an amorphous state, further confirming encapsulation. In vivo experiments demonstrated that GCN treatment significantly reduced lung injury scores fine particulate matter (PM2.5)-exposed mice (p < 0.05) alleviated epithelial barrier damage restoring decreased expression occludin protein 0.05). addition, PM2.5-induced upregulation MMP-9 COL1A1 mRNA levels, preventing extracellular matrix (ECM) degradation collagen accumulation exhibited antioxidant effects reducing nitric oxide synthase (iNOS) enhancing both superoxide dismutase (SOD-1) caused PM2.5, thereby alleviating oxidative stress A549 cells, reactive oxygen species (ROS) production compared 0.05), enhanced intracellular uptake confirmed using fluorescence microscopy conclusion, attenuating stress, suppressing apoptosis, preserving integrity. These results emphasize its as therapeutic candidate for treating diseases associated PM2.5 exposure.
