Macrophage Trogocytosis of Tumor Cells Drives the Immunosuppression of Tumor Microenvironment

open access: yesAdvanced Science, EarlyView.
Trogocytosis efficiency varies significantly among different tumor cells and is inversely related to their cortical stiffness; this efficiency dictates the extent of immunosuppression via upregulation of CXCL5 and Arg‐1, ultimately driving CD8+T cell exhaustion and tumor escape.

Tumor-specific but immunosuppressive CD39+CD8+ T cells exhibit double-faceted roles in clear cell renal cell carcinoma

open access: yesCell Reports Medicine
Summary: CD39+CD8+ T cells are known as tumor-antigen-specific cells among CD8+ tumor-infiltrating lymphocytes (TILs). However, CD39+CD8+ T cells also reportedly exhibit immunosuppressive activity in hypoxic tumor models.

FOXP1 Knockdown Reprograms Th9 CAR‐T Cells to Overcome Antigen Escape

open access: yesAdvanced Science, EarlyView.
FOXP1 knockdown enhances Th9 CAR‐T cell function by promoting IL‐9 production, effector activation, and reduced exhaustion. Reprogrammed Th9 CAR‐T cells strengthen direct tumor killing and activate endogenous antitumor immunity through dendritic cells and CD8+ T cells, thereby suppressing both antigen‐positive and antigen‐loss tumor growth and ...

Purinergic Signaling as a Regulator of Th17 Cell Plasticity. [PDF]

open access: yesPLoS ONE, 2016
T helper type 17 (Th17) lymphocytes, characterized by the production of interleukin-17 and other pro-inflammatory cytokines, are present in intestinal lamina propria and have been described as important players driving intestinal inflammation.

A humanized monoclonal antibody targeting CD39 with novel mechanism for cancer treatment

open access: yesMedicine in Drug Discovery, 2021
ATP-adenosine signal axis plays an import role in tumor immune regulation. ATP released by tumor cells can promote antitumor immunity, and adenosine can suppress the immune response.

Rat pancreas secretes particulate ecto-nucleotidase CD39

open access: yes, 2003
Udgivelsesdato: 2003-Sep-15In exocrine pancreas, acini release ATP and the excurrent ducts express several types of purinergic P2 receptors. Thereby, ATP, or its hydrolytic products, might play a role as a paracrine regulator between acini and ducts. The

A Tumor‐Boundary Niche Enriched for PD‐1+CD8+T Cells and BTLA+B Cells Drives Resistance to Immunotherapy in NSCLC

open access: yesAdvanced Science, EarlyView.
A spatial niche composed of BTLA+B cells and CD8+T cells is enriched at the tumor boundary in non‐small cell lung cancer. Within this specialized niche, BTLA+B cells act as a dominant source of IL‐6, upregulating PD‐1 on CD8+T cells via STAT3 signaling.
