Modulating Bacteroides to boost anti-PD-1 immunotherapy in HCC

Background
The gut microbiota is increasingly recognized as a critical external regulator along the gut-liver axis, influencing hepatocarcinogenesis and modulating responses to immunotherapy. However, the specific microbial determinants, underlying me…

Genetically engineered ErbB2 overexpression sensitizes organoid-derived tumors to checkpoint inhibition in a syngeneic model of gastric cancer

Background
ERBB2/HER2 is overexpressed or mutated in ~15% of gastric cancers due to amplification or mutation of the ERBB2 locus. While the tumor cell-intrinsic consequences of ERBB2 overexpression are well understood, much less is known about its eff…

Efficacy and safety of pembrolizumab, lenvatinib, and reduced-dose gemcitabine/oxaliplatin as initial treatment for advanced biliary tract cancer: a multicenter, single-arm, prospective, phase II study

Background
Biliary tract cancer (BTC) is an aggressive malignancy with limited treatment options and a poor prognosis. Although immune checkpoint inhibitors combined with chemotherapy have improved patient outcomes, their toxicity remains concerning. …

CD4+ T cells facilitate the RT-induced abscopal effect by promoting antigen cross-presentation to CD8+ T cells at unirradiated tumor sites

Background
The local effect of radiotherapy (RT) is enhanced by CD8+ T-cell responses elicited through dendritic cell (DC)-mediated cross-presentation of tumor antigens, facilitated by RT-induced damage-associated molecular patterns. The abscopal effe…

Oral immunization with Listeria monocytogenes vaccine enhances immunotherapy for protective immunity in murine models of colorectal cancer

Background
Colorectal cancer (CRC) is a leading cause of cancer-related death and remains a significant global health challenge. Cancer vaccines have emerged as a promising immunotherapy for long-term tumor control. While Listeria monocytogenes (Lm)-b…

Synergistic effects of anticoagulants and platelet aggregation inhibitors with immune checkpoint inhibitors in cancer therapy: a comprehensive review of preclinical and clinical evidence

Background
The rapidly advancing field of cancer therapy has sparked growing interest in the potential synergy between anticoagulation and immune checkpoint inhibitor (ICI) therapy. Recent research highlights that anticoagulants, traditionally used fo…

Tumor immune microenvironment facilitates resistance to KRAS G12C inhibitor sotorasib by altered PD-L1 expression.

Background
Acquired resistance to KRAS G12C inhibitor sotorasib remains a critical challenge in non-small cell lung cancer treatment. A deeper, rational understanding of resistance mechanisms can enable the development of therapeutic strategies to ove…

Potent antitumor activity through dual targeting of PD-L1 and TGF-{beta} pathways in the glioma tumor microenvironment

Background
Glioblastoma, one of the most aggressive brain tumors, has been largely resistant to conventional immunotherapies, underscoring the need for novel treatment approaches. A promising strategy involves simultaneously inhibiting immunosuppressi…
