Targeting RRBP1 reverses immune evasion and enhances immunotherapy efficacy via the CXCL10-CXCR3 axis in bladder cancer

Background
Crosstalk between inflammation and the immune system plays an important role in tumor malignant progression, immune evasion, and immunotherapy efficacy. This study aims to explore the significance of inflammation-associated gene ribosomal-b…

Multiomic analysis of colorectal adenocarcinoma reveals a new subtype of myofibroblastic cancer-associated fibroblasts that express high levels of B7-H3 and have poor-prognosis value

Background
The high mortality rate of patients with colorectal cancer combined with the lack of nontoxic and efficient personalized treatments makes it urgent to develop new targeted therapies for this disease. B7-H3 appears to be a good target, as it…

Oncolytic virus OH2 induces PD-L1 upregulation via NF-{kappa}B signaling and synergizes with anti-PD-L1 therapy in prostate cancer through a targeted extracellular vesicle delivery system

Background
Prostate cancer (PCa) is a prevalent malignancy with limited treatment options for advanced stages. Oncolytic virotherapy represents a promising immunotherapeutic approach, but its efficacy and underlying mechanisms in PCa, particularly con…

Optimizing anti-PI3K{delta} and anti-LAG-3 immunotherapy dosing regimens in a mouse model of triple-negative breast cancer improves outcome by removing treatment-related adverse events

Background
Current immunotherapy regimens most often fail due to an insufficient T cell response and/or immune-related adverse events (irAEs) which lead to treatment discontinuation. Additionally, many cancers likely require combination immunotherapie…

Partitioned overall survival: comprehensive analysis of survival states over 4 years in CheckMate 9ER comparing first-line nivolumab plus cabozantinib versus sunitinib in advanced renal cell carcinoma

Background
Immune checkpoint inhibitor (ICI)-based regimens can be associated with prolonged survival and disease control after treatment discontinuation without further anticancer therapy. An integrated, comprehensive partitioned survival analysis de…

Single-cell spatial transcriptomics uncovers niches that govern response to PD-1/PD-L1 blockade in cutaneous squamous cell carcinoma

Background
Neoadjuvant PD-1/PD-L1 blockade yields robust efficacy in advanced cutaneous squamous cell carcinoma (cSCC), yet many patients fail to achieve a complete or major pathologic response. The reasons why some patients experience response but ot…

Targeting PKMYT1 enhances antitumor immune responses to PD-L1 blockade in castration-resistant prostate cancer

Background
Although immunotherapy has revolutionized cancer treatment, its efficacy in castration-resistant prostate cancer (CRPC) remains limited, largely due to an immunologically “cold” tumor microenvironment with scarce T-cell infiltration. Unrave…

Clinical and translational results from a phase 1 trial of gemcitabine/nab-paclitaxel with nivolumab/ipilimumab or hydroxychloroquine/ipilimumab in untreated metastatic pancreatic adenocarcinoma

Background
Patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) often respond to cytotoxic therapy, but early disease progression is typical. Responses to immunotherapy alone are rare. Recent advances in chemoimmunotherapy combinations of…

Advancing ICOS agonism in solid tumors: lessons from INDUCE-1

The inducible T-cell co-stimulator (ICOS, CD278) represents an appealing yet complex target within the CD28 immunoglobulin receptor superfamily. Unlike constitutively expressed co-stimulatory molecules, ICOS is minimally present on naïve T cel…
