Purinergic system ecto-enzymes participate in the thromboregulation of patients with indeterminate form of Chagas disease.

Chagas disease (CD) is a chronic and endemic illness caused by the parasite Trypanosoma cruzi. Microvascular disturbances play an important role in the progress of the disease. The purinergic signaling system participates in regulatory functions, such as immunomodulation, neuroprotection, and thromboregulation.
