Angiotensin-converting enzyme 2: a new target for neurogenic hypertension

Angiotensin Converting Enzyme in Sarcoidosis

Brain-selective overexpression of human Angiotensin-converting enzyme type 2 attenuates neurogenic hypertension.

RATIONALE Angiotensin converting enzyme type 2 (ACE2) is a new member of the brain renin-angiotensin system, that might be activated by an overactive renin-angiotensin system. OBJECTIVE To clarify the role of central ACE2 using a new transgenic mouse model with human (h)ACE2 under the control of a synapsin promoter, allowing neuron-targeted expression in the central nervous system. METHODS ...

Brain angiotensin-converting enzyme type 2 shedding contributes to the development of neurogenic hypertension.

RATIONALE Overactivity of the brain renin-angiotensin system is a major contributor to neurogenic hypertension. Although overexpression of angiotensin-converting enzyme type 2 (ACE2) has been shown to be beneficial in reducing hypertension by transforming angiotensin II into angiotensin-(1-7), several groups have reported decreased brain ACE2 expression and activity during the development of hy...

New mass spectrometric assay for angiotensin-converting enzyme 2 activity.

A novel assay was developed for evaluation of mouse angiotensin-converting enzyme (ACE) 2 and recombinant human ACE2 (rACE2) activity. Using surface-enhanced laser desorption/ionization time of flight mass spectrometry (MS) with ProteinChip Array technology, ACE1 and ACE2 activity could be measured using natural peptide substrates. Plasma from C57BL/6 mice, kidney from wild-type and ACE2 knocko...

Angiotensin converting enzyme inhibitors and pulmonary hypertension.

AIM To evaluate the efficacy of angiotensin converting enzyme inhibitors Enalapril, Fosonopril and Moexipril on mean and systolic pulmonary artery pressure. MATERIAL AND METHODS The study included Ill patients with chronic obstructive bronchopneumopathies associated with arterial hypertension and mild to moderate heart failure (NYHA I-II class). The patients were examined at baseline and afte...
