Neurotoxicity caused by viral proteins, particularly the HIV-1 transactivator of transcription (Tat), contributes significantly to HAND. Although N-methyl-D-aspartate receptors (NMDARs) in astrocytes are known to regulate aquaporin-4 (AQP4) the mechanisms by which Tat influences NMDAR signaling and AQP4 expression remain unclear. This study investigated how HIV-1 Tat regulates AQP4 expression in astrocytes through the NMDAR/CaMKII/AC/cAMP/PKA signaling pathway and how secondary Ca2+ dynamics modulate this process. Astrocytic Ca2+ influx was measured using the Fluo-3 AM probe. Western blotting quantified AQP4, NR1, NR2A/B, CaMKII, p-CaMKII, PKA, and PKG expression. Real-time quantitative polymerase chain reaction (RT-qPCR) assessed mRNA levels of AQP4 and NMDAR-related genes. Enzyme-linked immunosorbent assay (ELISA) evaluated nitric oxide synthase activity, adenylate cyclase activity, and intracellular cAMP levels. Pharmacologic inhibitors-MK-801 (NMDAR blocker), H89 (PKA inhibitor), and KT5823 (protein kinase G [PKG] inhibitor)-were applied to investigate pathway interactions. HIV-1 Tat induced robust activation of NMDAR, resulting in increased Ca2+ influx and sequential activation of the CaMKII/AC/cAMP/PKA pathway, ultimately elevating AQP4. After prolonged Tat exposure (approximately 36 hours), a secondary surge in Ca2+ activated PKG, which acts as a protective negative feedback mechanism to inhibit excessive NMDAR activity, thereby stabilizing Ca2+ influx and preventing abnormal overexpression of AQP4. Cotreatment with MK-801, H89, or KT5823 suppressed Tat-induced Ca2+ influx and attenuated AQP4 upregulation, although persistent Tat exposure gradually restored Ca2+ elevations through compensatory mechanisms. HIV-1 Tat dynamically regulates AQP4 expression in astrocytes via the NMDAR/CaMKII/AC/cAMP/PKA pathway, with PKG-mediated feedback contributing to later stabilization. These findings highlight AQP4 as a potential therapeutic target for HAND.</p>","PeriodicalId":14560,"journal":{"name":"Iranian journal of allergy, asthma, and immunology","volume":"25 4","pages":"602-616"},"PeriodicalIF":1.5,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148420926","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}

While the Systemic Immune-Inflammation Index (SII) and Prognostic Nutritional Index (PNI) are recognized biomarkers for immune-inflammatory and nutritional status, their combined predictive value for POIs in liver surgery requires further investigation. This study evaluates SII and PNI as preoperative predictors for infections in this patient population. A retrospective observational study was conducted on 300 patients undergoing partial hepatectomy between 2022 and 2024. Preoperative laboratory data were used to calculate SII and PNI, with POIs identified within 30 days based on CDC guidelines. Statistical analyses, including multivariate logistic regression, were performed to compare infected and non-infected cohorts and identify independent predictors of infection. Of the 300 patients, 96 (32%) developed POIs. The infected group exhibited significantly higher SII (1142 ± 618 vs 792 ± 450) and lower PNI (40.1 ± 5.8 vs 46.4 ± 5.9) than the non-infected group. Multivariate analysis confirmed high SII (OR 2.85) and low PNI (OR 3.26; 95% CI, 2.01-5.12) as independent predictors. Furthermore, infections were associated with prolonged hospitalization, increased ICU admissions, and higher 30-day mortality. Preoperative SII and PNI are effective, independent predictors of POIs in patients undergoing hepatectomy for liver cancer.

In 2019, the integration of asthma-related services into this network was designed and pilot-tested. Primary health care providers (PHCPs) and family physicians (FPs) are the main members of the care provision team and are responsible for case identification and management. The pilot was conducted from November 2019 through April 2020 in seven areas-Kerman, Maragheh, Ahvaz, Kashan, Urmia, Karun, and Qazvin-covering both urban and rural locations and a population of approximately one million people. Our objective was to report indicators related to the integration of asthma identification, referral, and management within the existing primary health care system. In total, 350,894 individuals were screened for asthma by PHCPs. The observed proportion of positive (probable) cases among those screened was 2.48%. Key process indicators included screening uptake (34%), attendance of referred cases at physician visits (83%), and follow-up adherence (49% of confirmed cases). We conclude that improving screening uptake and the accuracy of asthma case detection by PHCPs are the most effective strategies for enhancing care provision efficiency. The findings of the pilot project have significant implications for understanding efficient integration of asthma-related services. The results indicate that integrating asthma care into primary health services is feasible and can improve early detection and care coordination, informing policy decisions for broader implementation and resource planning.</p>","PeriodicalId":14560,"journal":{"name":"Iranian journal of allergy, asthma, and immunology","volume":"25 4","pages":"617-622"},"PeriodicalIF":1.5,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148420928","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}

In this study, we examined PD-1 expression on NK cells from RA patients and evaluated whether miRNAs modulate this pathway. Although antibiotics are critical for treating infections, they can provoke harmful immune responses by releasing bacterial components that overstimulate the immune system. Such responses may lead to excessive inflammation or cytokine storms. To address this risk, we assessed the immune safety of a newly designed chimeric endolysin, ZAM-MSC, and compared its effects with traditional antibiotics using transcriptomic, proteomic, and computational analyses. We analyzed public gene and protein expression datasets from antibiotic-treated human cells and performed in silico studies on ZAM-MSC. Differential expression analysis and pathway enrichment were conducted, alongside structural modeling of the endolysin and its predicted interactions with immune receptors. Antibiotic treatment strongly activated inflammatory genes and pathways, including nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK). In contrast, ZAM-MSC minimally affected immune-related gene expression, with downregulation of interleukin-6 receptor (IL6R) and tumor necrosis factor receptor 1A (TNFRSF1A). Structural modeling showed weak interactions with Toll-like receptors, and epitope analysis predicted low immunogenicity.

Given the close relationship between cardiac injury and immune responses, understanding how anesthetic agents influence immune-related pathways may provide new insights into perioperative myocardial protection. This study aimed to explore the immunological and molecular mechanisms underlying the effects of sevoflurane anesthesia on cardiomyocytes in patients undergoing coronary artery bypass grafting (CABG). Gene expression data (GSE4386) from myocardial tissues of CABG patients anesthetized with sevoflurane or propofol were analyzed. Differentially expressed genes (DEGs) were identified using R software, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Protein-protein interaction networks were constructed to identify key immune-associated hub genes. A total of 211 DEGs were identified. Functional enrichment revealed that these genes were predominantly associated with immune and inflammatory processes, including leukocyte activation, cytokine-cytokine receptor interaction, neutrophil extracellular trap formation, and chemokine signaling pathways. Hub genes such as ITGAM, PTPRC, TYROBP, TLR2, and TLR4 were identified as central immune regulators potentially mediating the cardioprotective and immunomodulatory effects of sevoflurane. Sevoflurane anesthesia may confer myocardial protection after CABG by modulating immune-related signaling pathways and inflammatory gene expression.
