Decoding neoantigen-encoding tumor-specific transcripts unveils a shared target reservoir for immunotherapy in hepatocellular carcinoma

Background
Primary liver cancer, predominantly hepatocellular carcinoma (HCC), has limited therapeutic options. While mutation-derived neoantigen vaccine holds promise, its success is hindered by low antigen availability. This study explores transcrip…

Intratumoral Capnocytophaga leadbetteri promotes cancer cells proliferation and recruits neutrophils by activating TLR4/MyD88/NF-{kappa}B axis in oral squamous cell carcinoma

Background
Intratumoral bacteria influence the progression and treatment response of solid tumors through multiple mechanisms. Oral squamous cell carcinoma (OSCC) is a common malignant tumor in the head and neck; however, the role of intratumoral bact…

Spatial architecture of tertiary lymphoid structures represents an independent prognostic dimension in hepatocellular carcinoma

Background and aims
Tertiary lymphoid structures (TLS) are associated with heterogeneous outcomes in hepatocellular carcinoma (HCC), but whether their anatomical context determines clinical impact remains unknown. We hypothesized that spatial compartm…

Blautia coccoides-derived acetate potentiates anti-PD-1 immunotherapy in melanoma by activating cytotoxic CD8+ T cells

Background
Gut microbiota can modulate cancer immunotherapy and enhance the efficacy of programmed cell death protein 1 (PD-1) blockade in tumors, yet the responsible microbes and underlying mechanisms remain incompletely understood.

Methods
Publicly…

Anti-PD1-IL18 immunoconjugate promotes effector T cell-mediated antitumor immunity

Background
Immune checkpoint inhibitors have revolutionized cancer therapy, yet a substantial proportion of patients exhibit primary or acquired resistance. Immunocytokines offer a strategy to enhance antitumor immunity by delivering cytokine signals …

LysoPS-GPR34 axis enhances tumor-associated macrophages efferocytosis to promote immune escape in gastric cancer peritoneal metastasis

Background
Metabolites sculpt the immunosuppressive tumor microenvironment (TME) that facilitates immune evasion. As a crucial signaling lysophospholipid, lysophosphatidylserine (LysoPS) correlates with advanced disease stages in multiple tumor types….

Oncogenic PIK3CA mutation enhances tumor immunogenicity through the IRF1-NLRC5-MHC-I axis in urothelial carcinoma

Background
Immune checkpoint inhibitors (ICIs) have significantly improved overall survival in metastatic urothelial carcinoma (mUC). However, predictive biomarkers for therapeutic response remain insufficiently defined. Although some genomic alterati…

Neutrophil extracellular traps drive local tumor progression and metastasis following thermal ablation in liver cancer via TLR9-mediated inflammatory feedback and immunosuppression

Background
Local tumor progression and metastasis substantially compromise the therapeutic efficacy of thermal ablation in liver cancer. Although the inflammatory microenvironment contributes, the specific role of neutrophils after ablation remains un…

Galectin-9-driven immune evasion constrains radiotherapy-induced systemic antitumor immunity

While radiotherapy (RT) is effective for local tumor control, it rarely induces the regression of non-irradiated metastases, a phenomenon known as the abscopal effect. The mechanisms constraining this systemic immune response remain poorly understood….

IL-18 derived from microwave-ablated osteosarcoma facilitates antitumor response

Background
Osteosarcoma (OSA) is the most common primary malignant bone tumor in children and adolescents, while no further improvement in survival has been achieved in the past few decades. Microwave ablation (MWA) is an emerging thermal therapy to a…
