Circulating cytokines as potential dynamic biomarkers of PD-1 blockade response and prognosis in non-small cell lung cancer

Programmed death 1 (PD-1) inhibitors have transformed the treatment of advanced non-small cell lung cancer (NSCLC), but durable responses remain limited to a subset of patients. Conventional biomarkers, including PD-L1 expression and tumor mutational b…

PLA2G2F/lysoplasmalogen axis links epidermal lipid metabolism to type 2 inflammation and itch in atopic dermatitis

Atopic dermatitis is a chronic inflammatory skin disease characterized by type 2 immune responses and severe itching; however, the molecular mechanisms linking lipid metabolism to epithelial–immune signaling remain incompletely understood. Herein, we s…

Associations of polymorphisms in the myeloid immunoregulatory receptor gene MRC1 with expression and prognosis in acute myeloid leukemia

BackgroundAcute myeloid leukemia (AML) shows substantial biological and clinical heterogeneity that extends beyond leukemia-intrinsic genetic alterations. MRC1, which encodes the myeloid receptor CD206, has been linked to monocytic differentiation and …

A truncating ELF4 variant in a pediatric patient with autoinflammatory disease and cell type-specific immune alterations

IntroductionELF4 is an ETS family transcription factor involved in immune regulation, including antiviral responses and inflammatory signaling. Germline loss-of-function variants in ELF4 cause deficiency in ELF4, X-linked (DEX), a disorder characterize…

Semaglutide and pioglitazone restore airway mucosal homeostasis by resolving Pseudomonas aeruginosa pyocyanin-induced mucus hypersecretion, ciliostasis, and type 2 airway inflammation

RationaleChronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. As lung transplantation is the only curative option and current therapies are largely based on managing clinical symptoms, novel treatments are urgentl…

Exosome-mediated metabolic-immune regulatory axis: mechanisms of gastric cancer progression and resistance and targeting strategies

Gastric cancer (GC) is characterized by marked heterogeneity and frequent resistance to chemotherapy and immunotherapy. Exosomes mediate intercellular communication between tumor, stromal, and immune cells and may couple metabolic adaptation to immune …
