Ectonucleoside triphosphate diphosphohydrolase-1 (gene: ENTPD1; protein: NTPDase1) also known as CD39 (Cluster of Differentiation 39), is a typical cell surface enzyme with a catalytic site on the extracellular face.

Here, we first review the environmental and genetic factors shaping CD39 expression. Second, we report CD39 functions in the T cell compartment, highlighting its role in regulatory T cells, conventional CD4 + T cells and CD8 + T cells.

In this review, we provide a background on the molecular regulation of CD39 and CD73, outline the role of CD39 and CD73 in governing immune cell function, and detail the role of these enzymes in regulating the course of immune-mediated diseases.

CD39 is the cell surface-located prototypic member of the ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase) family. Biological actions of CD39 are a consequence (at least in part) of the regulated phosphohydrolytic activity on extracellular nucleotides.

Jul 29, 2020 · Recent findings reveal multipronged mechanisms of action of CD39 antagonism that rely not only on preventing the accumulation of adenosine but also on the stabilization of pro-inflammatory...

Jul 28, 2021 · Here, we first review the environmental and genetic factors shaping CD39 expression. Second, we report CD39 functions in the T cell compartment, highlighting its role in regulatory T cells, conventional CD4 + T cells and CD8 + T cells.

Jul 1, 2022 · Recent findings reveal that the ectonucleotidase CD39, the limiting enzyme been viewed as “immunological switch”, converts ATP-driven pro-inflammatory milieu to an anti-inflammatory state mediated by adenosine.

Jan 8, 2021 · Regulatory T cells (Tregs) play an indispensable role in maintaining immune homeostasis and CD39 is considered as a functional cell marker of Tregs. In this study, we aimed to evaluate the effect of CD39 + Tregs on acute lung injury (ALI) and investigate the frequency of CD39 + Tregs in ARDS patients.

CD39 expression is a promising surrogate of tumor-reactive CD8 + T cells. Here, we comprehensively profiled CD39 expression in human lung cancer. CD39 expression enriched for CD8 + T cells with features of exhaustion, tumor reactivity, and clonal expansion.

CD39, the endothelial ecto-nucleoside triphosphate diphosphohydrolase (NTPDase), regulates vascular inflammation and thrombosis by hydrolyzing ATP and ADP. Although ecto-NTPDase activities have been used as a marker of epidermal dendritic cells (DCs) known as Langerhans cells, the identity and funct …
