Introduction
Angiotensin-converting enzyme 2 is a membrane-bound enzyme primarily expressed in the lungs, heart, kidneys, intestines, and vascular endothelial cells. It plays a crucial role in regulating blood pressure and fluid balance by converting angiotensin II, a vasoconstrictor, into angiotensin (1-7), which has vasodilatory and anti-inflammatory properties. In addition to its role in cardiovascular homeostasis, angiotensin-converting enzyme 2 serves as the entry receptor for SARS-CoV and SARS-CoV-2, allowing viral attachment and cell entry, making it a key focus in infectious disease research.
