CD38 Protein

Ephrin-a receptor 7, also known as EphA7, belongs to the Ephrin receptor subfamily of the protein tyrosine kinase family. The Eph family is the largest group of related receptor tyrosine kinases known, consisting of 16 members in the vertebrate genome. EPHA7 functions as a repulsive guidance molecule during the targeting of retinal axons to the superior colliculus and of neocortical axons to the thalamus. At the same time, in recent years, more and more studies have shown that EphA7 protein is abnormally expressed in a variety of malignant tumors, involved in tumor occurrence and metastasis, and correlated with patient prognosis.Cluster of differentiation 38 (CD38) is a cell surface glycoprotein and multifunctional extracellular enzyme. As a NADase, CD38 produces adenosine through the adenosine energy pathway to cause immunosuppression. As a cell surface receptor, CD38 is necessary for immune cell activation and proliferation. Previous studies suggested that CD38 plays an important role in the regulation of macrophage function. Therefore, as a new marker of macrophages, the effect of CD38 on macrophage proliferation, polarization and function, its possible mechanism; the relationship between the expression level of CD38 on macrophage surfaces and disease diagnosis, treatment, etc.
