Modulating Bacteroides to boost anti-PD-1 immunotherapy in HCC

Background
The gut microbiota is increasingly recognized as a critical external regulator along the gut-liver axis, influencing hepatocarcinogenesis and modulating responses to immunotherapy. However, the specific microbial determinants, underlying me…

Unlocking the promise of innate biology through the HLA-G/ILT2/ILT4 pathway

Inhibitory immune pathways have gained considerable attention following the clinical success of immune checkpoint inhibitors in cancer. While much focus has been placed on classical checkpoints such as programmed cell death protein-1 (PD-1)/programmed…

Phase 1 open-label study of ASP9801, an oncolytic virus, in patients with advanced or metastatic solid tumors

Purpose
ASP9801, an oncolytic virus encoding interleukin-7 and interleukin-12, was assessed for safety, tolerability, pharmacokinetics, and antitumor activity in patients with advanced solid tumors in a Phase 1 study.

Methods
The study comprised Part…

Genetically engineered ErbB2 overexpression sensitizes organoid-derived tumors to checkpoint inhibition in a syngeneic model of gastric cancer

Background
ERBB2/HER2 is overexpressed or mutated in ~15% of gastric cancers due to amplification or mutation of the ERBB2 locus. While the tumor cell-intrinsic consequences of ERBB2 overexpression are well understood, much less is known about its eff…

Immunobiological mechanisms of action of oncolytic peptides

Oncolytic peptides (OLPs) constitute an emerging class of immunotherapeutics that combine direct cancer cell lysis with immune activation. Indeed, OLPs induce rapid immunogenic cell death by disrupting intracellular membranes, which culminates with th…

Harnessing tumor acidity: innovative lactic acid-responsive promoter enables precision control of CAR-T cell activity in solid tumors

Background
The acidic tumor microenvironment (TME) in solid tumors, driven by abnormal metabolism and lactic acid accumulation, suppresses chimeric antigen receptor-T (CAR-T) cell efficacy while posing safety risks from on-target, off-tumor toxicity (…

Efficacy and safety of pembrolizumab, lenvatinib, and reduced-dose gemcitabine/oxaliplatin as initial treatment for advanced biliary tract cancer: a multicenter, single-arm, prospective, phase II study

Background
Biliary tract cancer (BTC) is an aggressive malignancy with limited treatment options and a poor prognosis. Although immune checkpoint inhibitors combined with chemotherapy have improved patient outcomes, their toxicity remains concerning. …

CD4+ T cells facilitate the RT-induced abscopal effect by promoting antigen cross-presentation to CD8+ T cells at unirradiated tumor sites

Background
The local effect of radiotherapy (RT) is enhanced by CD8+ T-cell responses elicited through dendritic cell (DC)-mediated cross-presentation of tumor antigens, facilitated by RT-induced damage-associated molecular patterns. The abscopal effe…
