Antigen Spreading via Localized Administration Enhances Adoptive TCR‐T Cell Therapy in Pancreatic Cancer

Advanced Science, EarlyView.
Cancer vaccines face limitations in pancreatic cancer due to insufficient tumor antigens. This ionic liquid ILvax via local tumor delivery triggers robust cDC1‐dependent systemic anti‐tumor immunity. It boosts endogenous CD8+ T cells and optimizes adoptive TCR‐T function, providing a promising synergistic therapeutic strategy.

Genetic variants of human granzyme B predict transplant outcomes after HLA matched unrelated bone marrow transplantation for myeloid malignancies.

PLoS ONE, 2011
Serine protease granzyme B plays important roles in infections, autoimmunity, transplant rejection, and antitumor immunity. A triple-mutated granzyme B variant that encodes three amino substitutions (Q48R, P88A, and Y245H) has been reported to have ...

Single‐Cell RNA Editing Identifies T Cell ADAR1 as a Key Regulator of Immune Exhaustion and Anti‐PD‐1 Resistance in Colorectal Cancer

Advanced Science, EarlyView.
Single‐cell RNA editing analysis identifies ADAR1 as a regulator of dysfunctional T cell states in colorectal cancer. Elevated ADAR1 activity promotes T cell exhaustion and impairs antitumor immunity partly through TGF‐β‐SMAD signaling, contributing to anti‐PD‐1 resistance and highlighting T cell ADAR1 as a potential therapeutic target and biomarker ...

Single-Fluorescent Protein Reporters Allow Parallel Quantification of Natural Killer Cell-Mediated Granzyme and Caspase Activities in Single Target Cells

Frontiers in Immunology, 2018
Natural killer (NK) cells eliminate infected and tumorigenic cells through delivery of granzymes via perforin pores or by activation of caspases via death receptors.

Granzyme A binding to target cell proteins. Granzyme A binds to and cleaves nucleolin in vitro

Journal of Biological Chemistry, 1991
The physiologic substrates of cytotoxic T lymphocyte granule-associated serine esterases (referred to hereafter as proteases or "granzymes"), and the role of these enzymes in cell-mediated activity remain unclear. We have developed an assay for possible ligands of the trypsin-like dimeric serine protease granzyme A based on Western immunoblotting ...

Targeting a Myeloid–Regulatory B Cell Network Reverses Immune Paralysis in Periprosthetic Joint Infections

Advanced Science, EarlyView.
Periprosthetic joint infection establishes a sophisticated immunosuppressive network between CXCR4+ PMN‐MDSCs and Bregs, inducing profound CD8+ T cell paralysis. Alendronate effectively disrupts this CXCR4+ PMN‐MDSC–Breg axis by targeting STAT3, thereby restoring local immune surveillance.

De Novo Designed Minibinders Targeting the GDF15–GFRAL Axis Reverse Cancer Cachexia and Restore Anti‐Tumor Immunity

Advanced Science, EarlyView.
Tumor‐derived GDF15 drives cancer cachexia and suppresses antitumor immunity. Here, de novo designed minibinders targeting the GDF15–GFRAL interface achieve picomolar affinity and potent pathway blockade. The minibinders alleviate cachexia, restore CD8+ T‐cell infiltration, enhance anti–PD‐1 responsiveness, and provide survival benefits across tumor ...

UBE2O Drives Immune Evasion and Radioimmunotherapy Resistance in Lung Cancer by Degrading CDKL1 to Induce PD‐L1 Transcription

Advanced Science, EarlyView.
UBE2O targets CDKL1 for the degradation to upregulate PD‐L1 expression and promotes resistance to radioimmunotherapy in lung cancer, supporting the potential of targeting UBE2O as a promising therapeutic strategy. ABSTRACT Resistance to radioimmunotherapy is one of the primary causes of treatment failure in lung cancer patients; however, the underlying

Cytotoxic Function and Cytokine Production of Natural Killer Cells and Natural Killer T-Like Cells in Systemic Lupus Erythematosis Regulation with Interleukin-15

Mediators of Inflammation, 2019
Natural killer cells and NKT-like cells are the first line immune defense against tumor and virus infection. Deficient NK and NKT-like cell effector function may contribute to increased susceptibility to infection in SLE patients.

Targeting WDR12 Unleashes T‐Cell‐Mediated Antitumor Activity in Melanoma by Destabilizing CD276

Advanced Science, EarlyView.
WDR12 cooperates with the chaperonin subunit CCT7 to maintain CD276 stability on tumor cells, suppressing T‐cell activity and promoting immune escape. SU14813, a small‐molecule WDR12 inhibitor, reduces CD276 stability and relieves CD276‐mediated T‐cell suppression.
