Our results revealed that Cd73 (about 800-folds) and Cd157 (about 200-folds) expression increased greatly in mRNA level in purified FoxP3+Tregs from MI heart compared to that from the sham, and higher expression of Cd73 was found in Tregs than Teffs isolated from those infarcted heart. The gene discussed is NT5E; the disease is myocardial infarction.
