Biological background
In the immune system, CD39 plays an important role in controlling T cell and regulatory T cell activity. By reducing extracellular ATP levels and increasing adenosine production, CD39 dampens inflammatory responses and promotes immune tolerance. High CD39 expression on regulatory T cells contributes to their immunosuppressive capacity, making CD39 a focus of interest in autoimmune disease, transplantation, and cancer immunology. In the vascular system, CD39 helps prevent platelet aggregation and thrombosis by degrading platelet-activating nucleotides, thereby maintaining vascular health.
Dysregulation of CD39 expression or activity has been implicated in diverse diseases. Increased CD39 activity has been observed in tumors, where it contributes to immune evasion by creating an adenosine-rich, immunosuppressive microenvironment. Conversely, reduced CD39 function has been linked to heightened inflammation in autoimmune diseases and transplant rejection. These associations underscore CD39 as both a biomarker and a therapeutic target across multiple areas of biomedical research.
At the molecular level, CD39 is a transmembrane glycoprotein with two transmembrane domains and large extracellular loops that contain conserved apyrase motifs responsible for nucleotide hydrolysis. Its enzymatic activity is dependent on divalent cations such as calcium and magnesium. By regulating extracellular nucleotide concentrations, CD39 serves as a critical checkpoint in purinergic signaling pathways that influence vascular tone, immune cell communication, and tissue repair.
The CD39 antibody is commonly used in flow cytometry, western blotting, immunohistochemistry, and immunofluorescence to detect protein expression and distribution. These applications are valuable for research in immunology, oncology, and cardiovascular biology. For scientists investigating immune regulation, thrombosis, or purinergic signaling, the CD39 antibody provides a specific and dependable detection tool.
Research relevance and current trends
- Connecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).
- Considering isoforms and post-translational regulation when interpreting protein-level changes.
- Comparing results across species and model systems with matched controls.
Common research applications
- Western blotting: compare relative abundance and activation-state changes across conditions.
- Immunohistochemistry: map target signal in tissue context and compare regions/phenotypes.
Interpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.
Notes for experimental interpretation
- Signal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.
- Species differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.
Antibody notes: Monoclonal antibodies provide a defined epitope recognition profile that can support consistent comparisons across experiments.
