Urban aerosol particulate matter (UPM) is widespread in the environment, and its concentration continues to increase. Several recent studies have reported that UPM results premature cellular senescence, but few investigated molecular basis of UPM-induced senescence retinal pigment epithelial (RPE) cells. In this study, we primarily evaluated protective function nuclear factor erythroid 2-related 2 (Nrf2) human RPE ARPE-19 The findings indicated exposure substantially induced cells, as observed by increased β-galactosidase activity, expression levels senescence-associated marker proteins, phenotypes. Such associated with mitochondrial oxidative stress-mediated phosphatidylinositol 3'-kinase/Akt/Nrf2 downregulation. Sulforaphane-mediated Nrf2 activation upregulation phosphorylated suppressed decrease target antioxidant gene, NAD(P)H quinone oxidoreductase 1, under UPM, which notably prevented cells from senescence. By contrast, knockdown exacerbated promoted stress. Collectively, our demonstrate regulatory role suggest a potential target.

Abstract Background The small intestine harbors a rich array of intestinal intraepithelial lymphocytes (IELs) that interact with structural cells to collectively sustain gut immune homeostasis. Dysregulation homeostasis was implicated in the pathogenesis multiple autoimmune diseases, however, whether this is disrupted lupus background remains unclear. Methods We performed single-cell RNA sequencing (scRNA-seq) analyses elucidate and milieu epithelium MRL/Lpr mice (Lpr mice) MRL/Mpj control (Mpj mice). Comprehensive including unsupervised clustering, trajectories, cellular communication were performed. primary findings from scRNA-seq further validated by quantitative polymerase chain reaction (qPCR), flow cytometry, vivo experiments selenium supplementation. Results observed significant reduction CD8αα + IELs, accompanied marked increase CD8αβ IELs Lpr mice. Additionally, subsets CD8 exhibiting significantly enhanced effector functions found be markedly enriched Intercellular patterns within epithelial specifically altered Moreover, revealed decreased TCRγδ T (γδT) associated reduced aryl-hydrocarbon receptor repressor ( AHRR ) expression subsequent oxidative stress ferroptosis Antioxidant effectively reversed loss γδT mice, improved barrier, alleviated symptoms. Conclusions Our high-resolution atlas enhances understanding provides new insights into mediated dysregulation.

The lungs play a vital role in maintaining homeostasis by facilitating gas exchange and serving as structural immune barrier. External factors, including nutrition, lifestyle, environmental exposures, profoundly influence normal lung function contribute to the development, progression, prognosis of various respiratory diseases. Deficiencies key micronutrients, such vitamins A, D, C, well omega-3 fatty acids, can impair integrity epithelial lining, compromising lungs’ defense mechanisms increasing susceptibility injury disease. Obesity physical inactivity further disrupt inducing changes chest wall promoting pro-inflammatory state. Environmental pollutants worsen oxidative damage activate inflammatory pathways. Addressing these modifiable factors through interventions dietary optimization, activity programs, strategies reduce exposure offers promising avenues for preserving preventing disease progression. This review examines molecular pathways which influences impact homeostasis.
