Salt sensitivity of blood pressure in NKCC1-deficient mice.
NKCC1 is a widely expressed isoform of the Na-2Cl-K cotransporter that mediates several direct and indirect vascular effects and regulates expression and release of renin. In this study, we used NKCC1-deficient (NKCC1-/-) and wild-type (WT) mice to assess day/night differences of blood pressure (BP), locomotor activity, and renin release and to study the effects of high (8%) or low (0.03%) diet...
متن کاملHsd11b2 haploinsufficiency in mice causes salt sensitivity of blood pressure.
Salt sensitivity of blood pressure is an independent risk factor for cardiovascular morbidity. Mechanistically, abnormal mineralocorticoid action and subclinical renal impairment may blunt the natriuretic response to high sodium intake, causing blood pressure to rise. 11β-Hydroxysteroid dehydrogenase type 2 (11βHSD2) controls ligand access to the mineralocorticoid receptor, and ablation of the ...
متن کاملNeuropeptide Y and sympathetic nervous system in blood pressure regulation.
Neuropeptide Y and Sympathetic Nervous System in Blood Pressure Regulation To the Editor: We read with great interest the recent article by Dr Michalkiewicz and his colleagues1 dealing with a possible link between neuropeptide Y (NPY) and sympathetic nervous system in the NPY-transgenic rats. The results of their presented study demonstrated that overexpression of endogenous NPY in the transgen...
متن کاملKallikrein-kinin system and blood pressure sensitivity to salt.
We evaluated the blood pressure response to chronic salt loading in a rat strain inbred for low urinary kallikrein excretion. Low-kallikrein rats showed greater systolic blood pressure values (130 +/- 1 versus 114 +/- 2 mm Hg in controls; P < .05) at 9 weeks of age. Systolic blood pressure was increased after 10 days of dietary sodium loading in the low-kallikrein group and remained unchanged i...
متن کاملInteraction of the sympathetic nervous system with vasopressin and renin in the maintenance of blood pressure.
To evaluate the partial contributions and interaction of three vasopressor systems in blood pressure maintenance, nephrectomized rats and rats with intact kidneys were submitted sequentially to catecholamine depletion, elimination of vasopressin's vasoconstrictor action, and (for those with kidneys in situ) angiotensin blockade. Catecholamine depletion decreased blood pressure and stimulated va...
