Decoding ascitic immunological niches with multi-modal machine learning reveals prognostic and chemoresistant determinants in ovarian cancer

BackgroundMalignant ascites in high-grade serous ovarian cancer (HGSOC) represent a fluid extension of the tumor microenvironment, embedding immune programs that may inform prognosis and treatment response. We investigated whether ascitic T-cell phenot…

Single-cell RNA sequencing reveals heterogeneity among AT2 epithelial cells in the lung adenocarcinoma microenvironment

IntroductionLung cancer is a highly heterogeneous disease, and the tumor microenvironment (TME) characteristics are closely related to disease progression and treatment outcomes. We elucidated the cell type-specific transcriptome landscape of cancer ce…

CD47 expression in solid tumors correlates with phagocytic tumor-associated macrophage gene signature

BackgroundCD47 is a “don’t eat me” signal that is overexpressed in tumors to evade phagocytosis by tumor associated macrophages (TAM). Investigational agents targeting CD47, such as magrolimab, aim to induce phagocytosis of tumor cells by TAMs. Previou…

In the diffuse large B-cell lymphoma microenvironment, autophagy genes are upregulated in pro-inflammatory macrophages and linked to BCL2 overexpression

Diffuse large B-cell lymphoma (DLBCL) is one of the most frequent B-cell non-Hodgkin lymphoma types. It is characterized by a complex immune microenvironment, rich in macrophages (innate immunity cells), and high aggressiveness. DLBCL cells might respo…

Variant-adapted COVID-19 vaccine boosters enhance humoral immunity and limit IgG4 accumulation in solid cancer patients

BackgroundSolid cancer patients are at increased risk of severe COVID-19 and may benefit from repeated booster doses of SARS-CoV-2 mRNA vaccines. Beyond neutralizing antibody titers, recent evidence highlights the induction of spike-specific IgG4 after…

Administration of 2-deoxy-D-glucose induces pyroptosis in murine breast cancer cells via cAMP/PKA/HK2 to impair tumor survival

BackgroundBreast cancer poses a severe threat owing to its high morbidity and mortality rates, which are largely attributed to drug resistance. Therefore, novel therapeutic targets need to be identified. Pyroptosis is an inflammatory cell death process…

Development and validation of a machine learning-driven mitochondrial gene signature for the diagnosis of breast cancer

BackgroundBreast cancer (BC) ranks among the most prevalent malignant tumors in women globally, with mitochondrial dysfunction constituting one of its pathogenic mechanisms.ObjectivesTo investigate the relationship between mitochondrial function-relate…

Restoration of peripheral ILC3s by washed microbiota transplantation improves lipid profiles in hyperlipidemia patients

BackgroundThe contribution of circulating group 3 innate lymphoid cells (ILC3s) to lipid dysregulation has remained poorly defined, and the mechanisms through which washed microbiota transplantation (WMT) improves lipid metabolism require further clari…

Gut microbiota-driven dysbiosis of the SCFA-immune axis in pediatric allergic rhinitis-constipation comorbidity: mechanisms and synbiotic remodeling

BackgroundThe coexistence of allergic rhinitis (AR) and functional constipation (FC) in children reflects complex gut–immune interactions; however, the contribution of microbiota-derived short-chain fatty acids (SCFAs) to immune-metabolic dysregulation…
