LILRB2 blockade facilitates macrophage repolarization and enhances T cell-mediated antitumor immunity

Background
Immune checkpoint inhibitors have revolutionized the treatment of solid tumors, enhancing clinical outcomes by releasing T cells from inhibitory effects of receptors like programmed cell death protein 1 (PD-1). Despite these advancements, a…

Single-cell RNA sequencing of human double-negative T cells reveals a favorable cellular signature for cancer therapy

Background
Allogeneic double-negative T-cell (DNT) therapy has emerged as a novel, off-the-shelf cellular treatment with clinical feasibility, safety, and promising efficacy against leukemia. However, the biology of DNTs is less well characterized, an…

PCI-DB: a novel primary tissue immunopeptidome database to guide next-generation peptide-based immunotherapy development

Background
Various cancer immunotherapies rely on the T cell-mediated recognition of peptide antigens presented on human leukocyte antigens (HLA). However, the identification and selection of naturally presented peptide targets for the development of …

Neoadjuvant cobimetinib and atezolizumab with or without vemurafenib for stage III melanoma: outcomes and the impact of the microbiome from the NeoACTIVATE trial

Background
Neoadjuvant treatment has become standard for patients with high-risk operable stage III melanoma, but the optimal regimen is unknown. Targeted therapy approaches yield high pathological response rates, while immunotherapy regimens show fav…

METTL3 promotes an immunosuppressive microenvironment in bladder cancer via m6A-dependent CXCL5/CCL5 regulation

Background
Bladder cancer (BLCA) is a challenging malignancy with a poor prognosis, particularly in muscle-invasive cases. Despite recent advancements in immunotherapy, response rates remain suboptimal. This study investigates the role of METTL3, an m…

Irreversible electroporation synergizes with oncolytic virus enhances the infiltration of cytotoxic T lymphocytes in the tumor immune microenvironment: a leap from focal therapy to immunotherapy for prostate cancer

Irreversible electroporation (IRE), a non-thermal focal therapy, employs high-frequency electrical pulses to create tumor cell membrane nanopores, inducing immunogenic cell death. By triggering damage-associated molecular patterns, IRE activates dendr…

CD155 blockade enhances allogeneic natural killer cell-mediated antitumor response against osteosarcoma

Background
Allogeneic bone marrow transplant (alloBMT) is curative for hematologic malignancies through the graft-versus-tumor (GVT) effect but has been ineffective for solid tumors like osteosarcoma (OS). OS expresses CD155 which interacts strongly w…

Targeting B7-H3 inhibition-induced activation of fatty acid synthesis boosts anti-B7-H3 immunotherapy in triple-negative breast cancer

Background
Triple-negative breast cancer (TNBC) is the most malignant breast cancer, highlighting the need for effective immunotherapeutic targets. The immune checkpoint molecule B7-H3 has recently gained attention as a promising therapeutic target du…

Memory-promoting function of miR-379-5p attenuates CD8+ T cell exhaustion by targeting immune checkpoints

Background
MicroRNAs (miRNAs) are epigenetic regulators of T cell maturation and exhaustion. However, the mechanisms by which miRNAs influence T cell function in tumor environments remain unclear. This study focuses on miR-379-5p, which counteracts T …
