Cold Atmospheric Plasma‐Activated Decellularized Extracellular Matrix Gel as a Tumor‐Infiltrating Immunoactivation Platform for Post‐Surgical Cancer Immunotherapy

Advanced Materials, EarlyView.
An injectable cold atmospheric plasma‐activated decellularized tumor extracellular matrix hydrogel is introduced as a post‐surgical immunoactivation platform. The engineered gel attracts residual tumor cells and induces immunogenic cell death, reshaping the tumor microenvironment and eliciting systemic antitumor immunity. In combination with checkpoint

PD-L1, Galectin-9 and CD8+ tumor-infiltrating lymphocytes are associated with survival in hepatocellular carcinoma [PDF]

, 2017
Novel systemic treatments for hepatocellular carcinoma (HCC) are strongly needed. Immunotherapy is a promising strategy that can induce specific antitumor immune responses.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

The Expression and Biological Significance of PD-L1 on Lung Cancer Cell Lines [PDF]

, 2009
Background and objective Tumor-associated PD-L1 expression was recently shown to promote T-cell apoptosis and proposed as a potential mechanism of immune evasion by tumors. On the basis of the ability of tumor-associated PD-L1 to mediate activated T-cell

IFNγ-induced PD-L1 expression is JAK2 but not JAK1 dependent and its inhibition enhances NK-cetuximab mediated ADCC of HNSCC cells [PDF]

, 2014
Programmed death ligand 1 (PD-L1) is an immunosuppressive molecule expressed by many cancer types, including a large proportion of head and neck cancers (HNC), and ligation of its receptor, programmed death 1 (PD-1), induces exhaustion of effector T ...

A Reproducible and Scalable Process for High Yield Mesenchymal Stromal Cell Extracellular Vesicles Production

Advanced Materials Technologies, EarlyView.
Mesenchymal stem cell derived extracellular vesicles (MSC‐EVs) are a promising therapeutic tool for regenerative medicine. However, the field lacks a reproducible high‐yield production method to answer the quantities needed for clinical translation.

Association of Melanoma-Associated Antigen-A and Program-death ligand 1 Expression and Clinical Outcomes in Urothelial Carcinoma [PDF]

, 2019
Background: The melanoma-associated antigen-A (MAGE-A) and program-death ligand 1 (PD-L1) are present in urothelial carcinoma (UC). We aim to assess survival outcomes in patients with MAGE-A and PD-L1 expression.Methods: Analysis of MAGE-A and PD-L1 ...

Lack of PD-L1 Expression by iNKT Cells Improves the Course of Influenza A Infection [PDF]

, 2013
There is evidence indicating that invariant Natural Killer T (iNKT) cells play an important role in defense against influenza A virus (IAV). However, the effect of inhibitory receptor, programmed death-1 (PD-1), and its ligands, programmed death ligand ...

Interactions of Antibody Drug Conjugate Anti‐Tubulin and Topoisomerase I Inhibitor Payloads with Radiotherapy to Potentiate Immunotherapy

Advanced Science, EarlyView.
Antibody drug conjugates deliver their cytotoxic anti‐tubulin or topoisomerase I inhibitor payloads to tumors through cancer cell receptor targeting. The released drug payloads induce cellular changes that interact with radiotherapy resulting in radiosensitization that improves cancer cell kill and stimulates anti‐tumor immune responses.

Rigid, bivalent CTLA-4 binding to CD80 is required to disrupt the cis CD80/PD-L1 interaction

Cell Reports
Summary: The CTLA-4 and PD-1 checkpoints control immune responses and are key targets in immunotherapy. Both pathways are connected via a cis interaction between CD80 and PD-L1, the ligands for CTLA-4 and PD-1, respectively. This cis interaction prevents
