Arecoline upregulates CD155 expression to facilitate immune evasion in oral squamous cell carcinoma

Background
Areca nut is the fourth most addictive substance worldwide and is a known Group 1 carcinogen. Chronic areca nut chewing has been strongly associated with the development of oral squamous cell carcinoma (OSCC), although the underlying carcin…

Colorectal cancer organoids drive hypoxia, TGF-{beta}, and patient-specific diversification of NK cell activation programs

Background
Colorectal carcinoma exhibits high heterogeneity, comprising subtypes that show poor efficacy of T cell-based immunotherapies, such as programmed cell death protein 1 (PD-1) checkpoint inhibitors. Although natural killer (NK) cells are cons…

Adoptive cell transfer therapy with ex vivo primed peripheral lymphocytes in combination with chemotherapy in locally advanced or metastatic triple-negative breast cancer: the ImmunoBreast phase Ib clinical trial

Background
Adoptive cell transfer-based immunotherapy holds promise for treating advanced cancer. However, a key challenge remains: generating sufficient numbers of lymphocytes capable of recognizing and targeting a broad range of cancer antigens. We …

NEAT1 is a therapeutic target for reversing T-cell exhaustion in bladder cancer

Background
T-cell exhaustion induced by the tumor microenvironment is an important factor in posing a major challenge to effective cancer immunotherapy. Immune checkpoint inhibitors aim to reverse T-cell exhaustion. However, the effectiveness of immun…

Biomimetic carbon nanopolymers ANM-NPs act on mannose receptors and complement receptors to promote tumor antigen presentation

Background
Enhancing immunogenicity and antigen-presentation efficiency is critical for tumor vaccine development. While yeast-surface glycoprotein side chains can improve antigen presentation, their ability to deliver tumor antigens remains limited.

Single-cell multiomics reveals macrophage-derived IL-23 and CXCL9/10 drive pathogenic IFNG+IL17+ T cells in immunotherapy-related colitis

Background
Immune checkpoint blockade (ICB) therapy, while transformative in cancer treatment, is frequently complicated by immune-related colitis (irColitis), driven by poorly understood mechanisms.

Methods
An integrated analysis of single-cell RNA …

Neoadjuvant personalized viral vaccine prevents tumor relapse in checkpoint-resistant murine melanoma model

Background
Personalized cancer vaccines targeting tumor-specific neoantigens (nAgs) are an emerging therapeutic strategy, particularly effective in early-stage disease before immune suppression is established. Immune checkpoint inhibitors have demonst…

HSP47 inhibition-induced CD155 expression through TRAF2 deubiquitination promotes tumor immune evasion

Background
Heat shock protein 47 (HSP47) is crucial for protein quality control and tumor progression. While its role in cancer biology is well established, its impact on cancer immunity remains poorly understood. In this study, we aim to elucidate ho…

Second-event endpoints (EFS2, PRFS2 and PFS2) after anti-PD-(L)1-based RCTs: a systematic review and meta-analysis

Background
Immune checkpoint inhibitors (ICIs), particularly anti-PD-(L)1s, have transformed cancer care by their extended efficacy, even receiving next-line. Event-free survival 2 (EFS2), progression/recurrence-free survival 2 (PRFS2) and progression…
