Clinical trial landscape and translational prospects of natural killer cell-based immunotherapy: an analysis based on the INFORMA database

Natural killer (NK) cell-based immunotherapy is an increasingly important cancer treatment strategy because of its innate cytotoxicity, allogeneic potential, and compatibility with off-the-shelf manufacturing. We analyzed 287 clinical trials identifie…

Streptococcus anginosus-associated kynurenic acid drives PD-1 blockade resistance through an ITGA2-mTOR-CTSV axis in gastric cancer

Background
The tumor microbiota critically shapes responses to immunotherapy; however, the mechanisms by which specific microbial species drive immune checkpoint blockade (ICB) resistance in gastric cancer (GC) remain poorly defined.

Methods
Streptoc…

Targeting GRP75 by natural compound polyphyllin II triggers mitochondrial calcium overload and pyroptosis to potentiate cancer immunotherapy

Background
Immune checkpoint blockade (ICB) therapy has emerged as a pivotal cancer treatment by activating antitumor immunity. However, its clinical efficacy remains limited in many patients, highlighting the need for combination strategies to overco…

Loss of NCCRP1 overcomes immune evasion in lung adenocarcinoma

Background
The low response rate to immunotherapy in patients with lung adenocarcinoma is primarily due to tumor immune evasion. The tumor immunosuppressive microenvironment orchestrates this evasion, yet the underlying mechanisms remain elusive. Here…

“Yong” syndrome-cGAS-STING axis: a TCM syndrome-based hypothesis for overcoming primary anti-PD-1 resistance in gastric cancer

Gastric cancer (GC) remains a major clinical challenge, with most patients exhibiting primary resistance to anti-programmed cell death protein-1 (anti-PD-1) immunotherapy and a lack of effective predictive biomarkers. Most advanced GC presents as immu…

Focused ultrasound thermal ablation and CD40 agonism reprograms breast tumor immunity to drive regression and memory

Background
Focused ultrasound thermal ablation (T-FUS) is a clinically accessible, non-invasive modality capable of inducing rapid tumor cytoreduction while mobilizing early immunologic danger signals. However, its capacity to synergize with potent co…

TGF-{beta}1 drives neutrophil extracellular traps formation to promote CD8+ T cell exhaustion via the ERK-c-Fos-JunB axis, mediating gastric cancer immunotherapy resistance

Background
Resistance to anti-programmed cell death protein-1 (PD-1) treatment in gastric cancer (GC) is closely associated with an immunosuppressive tumor microenvironment. However, the role of neutrophils in resistance to anti-PD-1 therapy remains u…

{beta}-glucan elicits APOE-dependent peripheral trained immunity to suppress hepatocellular carcinoma

Background
Although immunotherapy has revolutionized cancer treatment, hepatocellular carcinoma (HCC) continues to demonstrate limited clinical responses, highlighting the urgent need for novel immunomodulatory strategies. Trained immunity, an emergin…

Tumor stroma-immune interactions shape the immunosuppressive microenvironment and predict response to neoadjuvant chemoradiotherapy plus immunotherapy in rectal cancer

Background
The tumor microenvironment, particularly the tumor stroma, plays a critical role in tumor progression, immune evasion, and therapeutic resistance. However, its interaction with the immune landscape in rectal cancer (RC) remains incompletely…

Efficient discovery of an agonistic anti-OX40 nanobody by epitope-directed approach to address enrichment-driven epitope bias

Background
Conventional antibody discovery approaches that do not account for enrichment-driven biases, such as epitope immunogenicity, PCR amplification bias, or protein expression efficiency, may result in under-representation of rare yet functional…
