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)…

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…

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…

High Treg and PMN-MDSC densities are a hallmark of tertiary lymphoid structures in fatal cases of cervical cancer

Background
High densities of tertiary lymphoid structures (TLSs) are associated with improved clinical outcomes in various malignancies, including human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC). However, the role o…

T-cell responses against CD19-targeted CAR T cells varnimcabtagene autoleucel (ARI-0001): implications for immune response and therapy outcomes

Patients with B-cell malignancies receiving CD19-targeted chimeric antigen receptor (CAR) T-cell therapy may experience treatment failure due to various mechanisms. One significant factor is the host’s immune response against the CAR-T product, …
