Macrophage NLRP3 activation and IL-1{beta} release drive osimertinib-induced antitumor immunity

Background
Despite the clinical efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in non-small cell lung cancer (NSCLC), patient outcomes vary even among those with identical EGFR mutations. This study investigates wh…

O-GlcNAc transferase promotes immune evasion and immunotherapy resistance in uterine corpus endometrial cancer by targeting the glucocorticoid receptor

Background
Although some tumors respond to immune checkpoint blockade therapy, checkpoint inhibitors have been unsuccessful in treating uterine corpus endometrial cancer (UCEC), and the underlying molecular mechanisms remain unclear.

Methods
We inves…

Preliminary qualification of a machine learning-based assessment of the tumor immune infiltrate as a predictor of outcome in patients with hepatocellular carcinoma treated with atezolizumab plus bevacizumab

Spontaneously immunogenic hepatocellular carcinoma (HCC), identified by a dense immune cell infiltrate (ICI), responds better to immunotherapy, although no validated biomarker exists to identify these cases. We used machine learning (ML) to quantify I…

Targeting immunosuppressive macrophages by CSRP2-regulated CCL28 signaling sensitizes hepatocellular carcinoma to lenvatinib

Background
Despite comparable survival benefit has been obtained, the drug resistance remarkably reduced lenvatinib clinical efficacy. Here, we aimed to identify the potential mechanism by which cysteine and glycine-rich protein 2 (CSRP2) regulates th…

Abscopal effects in patients with malignant melanoma treated with radiotherapy and immune checkpoint inhibition: analysis of a large observational multicenter study

Background
Abscopal effect (AbE), the regression of non-irradiated metastatic lesions (NILs) following radiotherapy (RT), is relevant in patients with malignant melanoma (MM) with progressive disease (PD) under immune checkpoint inhibition (ICI) as re…

T cell subsets of urine-derived lymphocytes (UDLs) serve as an indicator of TILs and reflect immunological sex differences in bladder cancer

Background
Bladder cancer is unique among visceral malignancies in that urine, which can be easily obtained, has prolonged contact with bladder tumors. Urinary biomarkers offer the potential to provide insight into the host and tumor immune microenvir…

Spatial transcriptomic profiling of metastatic renal cell carcinoma identifies chemokine-driven macrophage and CD8+ T-cell interactions predictive of immunotherapy response

Background
Metastatic renal cell carcinoma (mRCC) still lacks tissue-based biomarkers that predict benefit from first-line immune checkpoint inhibitor (ICI) regimens. High-resolution spatial transcriptomics can dissect the tumor microenvironment (TME)…

Dynamic modulation of claudin18.2 expression and remodeling of the tumor microenvironment in gastric cancer during chemo-immunotherapy

Background
Claudin 18.2 (CLDN18.2) is a tight junction protein retained in malignant transformation of gastric cancer (GC) and is a promising therapeutic target. Despite the clinical benefit of zolbetuximab in CLDN18.2-positive tumors, the dynamic exp…

Antagonism of estrogen-related receptor-{alpha} inhibits mitochondrial oxidative phosphorylation and reduces M2 macrophage infiltration in endometrial cancer

Objective
Endometrial cancer (EC) is a female malignancy closely linked to metabolic dysregulation. Most patients with EC exhibit poor responses to immunotherapy, underscoring the need to identify novel therapeutic targets at the intersection of metab…
