This complex also enhances the uptake of oxLDL, thereby accelerating foam cell formation through the Toll-like receptor-4/nuclear factor kappa B (TLR4/NF-κB) pathway. Given the critical role of macrophage autophagy in the instability of vulnerable atherosclerotic plaques, it is imperative to investigate whether the oxLDL/β2GPI/anti-β2GPI complex influences macrophage autophagy in AS. This study aims to elucidate the effects and underlying mechanisms of the oxLDL/β2GPI/anti-β2GPI complex on macrophage autophagy in AS.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Experiments were conducted using murine macrophage RAW264.7 cells and the human monocytic cell line THP-1.

An increase in the phosphorylation levels of phosphoinositide-3-kinase (PI3K), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) was also observed. Notably, the expressions of autophagy-associated markers were partially restored when the TLR4/NF-κB and PI3K/AKT/mTOR pathways were inhibited by their respective inhibitors.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Our findings indicate that the oxLDL/β2GPI/anti-β2GPI complex inhibits macrophage autophagy in AS via the TLR4/NF-κB and PI3K/AKT/mTOR signaling pathways.</p>\u0000 </section>\u0000 </div>","PeriodicalId":13289,"journal":{"name":"Immunity, Inflammation and Disease","volume":"12 11","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11542296/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142604099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of data to elucidate the role of inflammatory variables in asthma. This study aimed to compare the levels of inflammatory factors in serum and sputum in children with acute and stable asthma to those in healthy children and the ability to predict clinical response to azithromycin therapy.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This study recruited 95 individuals aged 1−3 years old and collected data from January 2018 to 2020. We examined serum and sputum inflammatory factors and constructed the least absolute shrinkage and selection operator (LASSO) model. Predictive models were constructed through multifactor logistic regression and presented in the form of column-line plots. The performance of the column-line diagrams was measured by subject work characteristics (ROC) curves, calibration plots, and decision curve analysis (DCA). Then, filter-paper samples were collected from 45 children with acute asthma who were randomly assigned to receive either azithromycin (10 mg/kg, <i>n</i> = 22) or placebo (<i>n</i> = 23).

The levels of interferon-γ (IFN-γ), tumor necrosis factor-a (TNF-α), chemokine CCL22 (CCL22), interleukin 12 (IL-12), chemokine CCL4 (CCL4), chemokine CCL2 (CCL2), and chemokine CCL13 (CCL13）were significantly higher in the acute asthma group than in the stable asthma group. A logistic regression analysis was performed using CCL22 and IL-1 as independent variables. Additionally, IFN-γ, TNF-α, IL-1, IL-13, and CCL22 were identified in the LASSO model.
