Abstract: Disclosed are variants of ACE2, pharmaceutical compositions comprising the variants of ACE2, and treatment methods for reducing Angiotensin II(1-8) plasma levels and/or increasing Angiotensin (1-7) plasma levels in a subject in need thereof. The disclosed variants of ACE2 may include polypeptide fragments of ACE2 having ACE2 activity for converting AngII(1-8) to Ang(1-7). Suitable subjects suitable for the disclosed methods of treatment may include subjects having or at risk for developing diabetic and non-diabetic chronic kidney disease, acute renal failure and its prevention, chronic kidney disease, severe hypertension, scleroderma and its skin, pulmonary, kidney and hypertensive complications, malignant hypertension, renovascular hypertension secondary to renal artery stenosis, idiopathic pulmonary fibrosis, liver fibrosis such as in liver cirrhosis patients, an aortic aneurysm, cardiac fibrosis and remodeling, left ventricular hypertrophy, and an acute stroke.

Abstract: The present disclosure provides various insights relating to treatment of viral infection with soluble ACE2 variants, specifically including soluble human ACE2 (hACE2) variants. For example, the present disclosure teaches that decoy activity, which may intercept virus-receptor interactions, and ACE2 enzymatic activity can provide separate contributions to therapeutic efficacy; among other things, the present disclosure provides particular therapeutic regimens (e.g., relating to treatment of particular patient populations and/or to dosing regimens, combination therapies, etc.) for certain soluble ACE2 variants. Still further, the present disclosure provides certain particular ACE2 variants and methods of making and/or using them, including in accordance with particular therapeutic regimens.

Abstract: The present invention provides a method for enhancing expression of angiotensin converting enzyme ACE2 in the vasculature of a mammal, particularly in the renal vasculature and podocytes. The method comprises administering to a mammal in need of such enhancement (e.g., a mammal suffering from, or at risk of developing renal damage or hypertension), an amount of an angiotensin II antagonist sufficient to promote a protective level of ACE2 expression in the vasculature of the mammal. Preferably, the angiotensin II antagonist is administered in an angiotensin II blocking amount, more preferably in an amount sufficient to achieve and maintain a desired level of ACE2 expression in the vasculature of the mammal. The methods of the invention are useful for ameliorating kidney damage from diseases, such as diabetes, as well as hypertension.
