Beyond this, PD-L1’s intrinsic signaling pathways within cancer cells warrant further exploration. This study aims to elucidate the effect of PD-L1 stimulation on the proliferation, survival, and apoptosis of acute myeloid leukemia (AML) cell lines.
 Two human AML cell lines, HL-60 and THP-1 were cultured and treated with phorbol 12-myristate 13-acetate (PMA) to induce PD-L1overexpression. Post-treatment PD-L1 expression was confirmed via flow cytometry. Subsequently, cell surface PD-L1 was stimulated using a recombinant PD-1, 24 hours post-PMA treatment. The expression alterations in pivotal genes including BCL2, MKI67, BAX, and CASP3 were monitored using quantitative real-time polymerase chain reaction 24 and 48 hours post-treatment. Additionally, annexin-V through flow cytometry.
 Findings reveal that PD-L1 stimulation augments AML cell proliferation and survival by enhancing MKI67 and BCL2 expressions while concurrently inhibiting cell apoptosis due to decreased BAX and CASP3 expression following PD-L1 stimulation. Notably, stimulated cells expressed exhibited reduced annexin-V compared to control cells.
 This study underscores that PD-L1 stimulation fosters AML cell proliferation and survival while impeding cell apoptosis. The results hold potential implications for targeting PD-L1 in AML treatment strategies.","PeriodicalId":14560,"journal":{"name":"Iranian journal of allergy, asthma, and immunology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135476707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disease severity has been linked to proinflammatory cytokines which activate the NF-κB and STAT transcription factors in infected cells. It has been proven that lncRNAs play a very important role in reducing or increasing inflammatory factors. This makes them potentially valuable in recognizing pathogenesis pathways and therapeutic targets in COVID-19. Nanocurcumin is known as an antioxidant, tumor suppressor and anti-inflammatory substance, and it can be effective to reduce inflammation caused by the disease of COVID-19. This study analyzed Sequence Read Archive data from COVID-19 patients with acute versus milder symptoms, identifying dysregulated genes and non-coding RNAs. To verify this correlation, the expression of the candidate gene was evaluated with quantitative polymerase chain reaction (qPCR) in mouse models, while immunoglobulin (Ig) G titer was measured using enzyme-linked immunosorbent assay (ELISA) in mouse serum samples. Here we introduced a novel lncRNA called HSD17B3-AS1, suggested as a therapeutic target in COVID-19 patients with acute symptoms. Furthermore, we revealed nanocurcumin is reducing the expression of HSD17B3-AS1 which leads to reduced inflammation in mice.
