Depletion of myeloid-derived suppressor cells sensitizes murine multiple myeloma to PD-1 checkpoint inhibitors

Background
Cancer immunotherapy using immune checkpoint blockade (ICB) has revolutionized cancer treatment. However, patients with multiple myeloma (MM) rarely respond to ICB. Accumulating evidence indicates that the complicated tumor microenvironment…

Neoadjuvant atezolizumab + chemotherapy for resectable NSCLC: 3-year clinical update of phase II clinical trial results and translational findings

Introduction
Neoadjuvant chemoimmunotherapy has achieved overall survival (OS) benefit for patients with resectable non-small cell lung cancer (NSCLC). Here, we present outcomes after 3 years of follow-up from the first reported study of neoadjuvant a…

Krebs von den Lungen-6 surveillance in immune checkpoint inhibitor-induced pneumonitis

Background
The immune-related adverse event (irAE), pneumonitis, is a potentially fatal complication of immune checkpoint inhibitors (ICIs). Preventing its progression is crucial, emphasizing the need for effective screening tests. We evaluated the fe…

Optimal timing of anti-PD-1 antibody combined with chemotherapy administration in patients with NSCLC

Background
Anti-programmed cell death 1 (PD-1) antibody combined with chemotherapy simultaneously is regarded as the standard treatment for patients with advanced non-small cell lung cancer (NSCLC) by current clinical guidelines. Different immune stat…

Personalized neoantigen hydrogel vaccine combined with PD-1 and CTLA-4 double blockade elicits antitumor response in liver metastases by activating intratumoral CD8+CD69+ T cells

Background
Liver metastasis is highly aggressive and immune tolerant, and lacks effective treatment strategies. This study aimed to develop a neoantigen hydrogel vaccine (NPT-gels) with high clinical feasibility and further investigate its efficacy an…

LKB1 dictates sensitivity to immunotherapy through Skp2-mediated ubiquitination of PD-L1 protein in non-small cell lung cancer

Background
Loss-of-function mutations of liver kinase B (LKB1, also termed as STK11 (serine/threonine kinase 11)) are frequently detected in patients with non-small cell lung cancer (NSCLC). The LKB1 mutant NSCLC was refractory to almost all the antit…

Multiomics reveals tumor microenvironment remodeling in locally advanced gastric and gastroesophageal junction cancer following neoadjuvant immunotherapy and chemotherapy

Background
Perioperative chemotherapy is the standard of care for patients with locally advanced gastric and gastroesophageal junction cancer. Recent evidence demonstrated the addition of programmed cell death protein 1 (PD-1) inhibitors enhanced ther…

Novel tri-specific T-cell engager targeting IL-13R{alpha}2 and EGFRvIII provides long-term survival in heterogeneous GBM challenge and promotes antitumor cytotoxicity with patient immune cells

Background
Glioblastoma multiforme (GBM) is known for its high antigenic heterogeneity, which undermines the effectiveness of monospecific immunotherapies. Multivalent immunotherapeutic strategies that target multiple tumor antigens simultaneously cou…

TMED inhibition suppresses cell surface PD-1 expression and overcomes T cell dysfunction

Background
Blockade of the programmed cell death protein 1 (PD-1) immune checkpoint (ICB) is revolutionizing cancer therapy, but little is known about the mechanisms governing its expression on CD8 T cells. Because PD-1 is induced during activation of…

Cancer-associated fibroblasts shape early myeloid cell response to chemotherapy-induced immunogenic signals in next generation tumor organoid cultures

Background
Patient-derived colorectal cancer (CRC) organoids (PDOs) solely consisting of malignant cells led to major advances in the understanding of cancer treatments. Yet, a major limitation is the absence of cells from the tumor microenvironment, …
