To elucidate these mechanisms, we profiled peripheral blood mononuclear cells (PBMCs) from patients before and after thoracic radiotherapy using single-cell RNA sequencing (scRNA-seq), with key findings validated via multiparameter flow cytometry and ELISA assays. Our analysis revealed that radiotherapy markedly reshaped the immune composition, expanding innate myeloid cells (monocytes and neutrophils) and reducing lymphocytes (T and NK cells); these compositional shifts were independently confirmed by flow cytometric analysis. Cell-cell communication networks showed that postradiotherapy monocytes evolved into central signaling hubs, exhibiting heightened proinflammatory ligand-receptor interactions. Consistent with this, monocytes showed broad transcriptional reprogramming with upregulation of canonical inflammatory pathways (IL-6/STAT3, TNF/NF-κB) and metabolic regulators (mTORC1, glycolysis). ELISA assays corroborated these transcriptomic signatures, demonstrating significantly elevated plasma levels of IL-6 and TNF-α post-treatment. Notably, scRNA-seq identified a selective expansion of the highly plastic intermediate (CD14++CD16+) monocyte subset, a specific population shift further verified by flow cytometry. These intermediate monocytes exhibited an immature, progenitor-like profile and were enriched at the origin of a Monocle3 pseudotime trajectory. Trajectory analysis indicated they differentiate into mature classical monocytes that upregulate proinflammatory effector genes such as S100A8, S100A9, and S100A12. Furthermore, pseudotime gene clustering revealed a functional bifurcation in monocyte behavior: one module drove inflammatory activation, while a second module simultaneously engaged oxidative stress responses and antioxidant defenses (e.g., glutathione metabolism). In summary, by integrating single-cell transcriptomics with experimental validation, we demonstrate that radiotherapy drives a systemic immune shift characterized by intermediate monocyte expansion and bifurcated programs of inflammation and stress adaptation. Intermediate monocytes emerge as key drivers of postradiotherapy inflammation, offering a potential cellular biomarker of RIHD risk and a target for immunomodulatory interventions to mitigate cardiovascular injury in cancer survivors.</p>","PeriodicalId":9494,"journal":{"name":"Cardiology Research and Practice","volume":"2026 ","pages":"1117746"},"PeriodicalIF":1.8,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13090681/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147721586","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}

The identification and management of CS heavily depend on advanced cardiac imaging techniques. The article examines multimodality imaging in CS by evaluating cardiac magnetic resonance (CMR) imaging, positron emission tomography (PET) with computed tomography (CT), single-photon emission computed tomography (SPECT), echocardiography, CT and hybrid imaging approaches. This review examines each imaging modality with respect to its fundamental principles, diagnostic capabilities, benefits and drawbacks and references key research from the past decade. CMR stands as the primary diagnostic method for detecting myocardial scar and fibrosis in CS patients, providing essential prognostic information. The PET/CT system with 18-fluorodeoxyglucose (FDG) provides an effective method for detecting active inflammation and tracking treatment response. Echocardiography is a readily accessible screening tool that reveals the structural and functional effects of CS, while strain imaging techniques enable the detection of early disease involvement. The use of delayed-enhanced cardiac CT provides an alternative method for detecting myocardial scar. It helps identify patients who are ineligible for CMR and excludes coronary artery disease. Diagnostic confidence and disease activity assessment improve with hybrid imaging, particularly when PET/MR is used. The Discussion section integrates these findings with an evaluation of emerging quantitative imaging markers and novel tracers that show promise for enhancing CS evaluation. The implementation of multimodality imaging techniques has transformed the management of CS by enabling earlier diagnosis, risk assessment and treatment guidance.

Originally discovered in nerve injury, it has been extensively studied for its role in nerve regeneration. Ninj1 mediates the transendothelial migration of myeloid cells mainly through the extracellular adhesion domain, thereby aggravating the inflammation of the central nervous system. In addition to regulating the inflammatory phenotype of cells, Ninj1 actively mediates the rupture of the plasma membrane and regulates the programmed death of inflammatory cells, thereby participating in the host defense against exogenous infection. In recent years, Ninj1, an important protein associated with inflammasome activation, has garnered increasing attention from researchers regarding its mechanistic role and pathophysiological significance in cardiovascular diseases. Accumulating evidence suggests that Ninj1 not only participates in the regulation of inflammatory responses and cell death processes but also plays a critical role in the onset and progression of various cardiovascular conditions, including atherosclerosis, myocardial ischemia-reperfusion injury, and heart failure. Therefore, an in-depth exploration of the specific functions of Ninj1 in the cardiovascular system holds significant scientific and clinical value for elucidating the molecular mechanisms underlying these diseases and for developing novel therapeutic strategies.
