Neuroprotective effects of angiotensin II type 1 receptor (AT1R) blocker, telmisartan, via modulating AT1R and AT2R signaling in retinal inflammation.
PURPOSE To investigate the retinal neural damage that occurs during inflammation and the therapeutic effects of the angiotensin II type 1 receptor (AT1R) blocker, telmisartan, using a model of endotoxin-induced uveitis (EIU). METHODS The localization of AT1R and AT2R was shown by immunohistochemistry. EIU was induced by intraperitoneal injection of lipopolysaccharide (LPS). Animals were treat...
متن کاملP-218: Investigation of Association between Angiotensin II Type 1 and 2 Receptor (AT1R & AT2R) Gene Polymorphisms and Susceptibility to Pre-Eclampsia (PE) in Iranian Women
Background: Hypertension during pregnancy period along with the presence of protein in the urine, after the 20th weeks of gestation is called preeclampsia (PE). About five percent of all pregnancies are manifested with PE and its exact etiology has still remained unknown. The renin-angiotensin system (RAS) has an important role in the regulation of blood pressure during pregnancy and so pathoph...
متن کاملInfluence of Angiotensin II Subtype 2 Receptor (AT2R) Antagonist, PD123319, on Cardiovascular Remodelling of Aged Spontaneously Hypertensive Rats during Chronic Angiotensin II Subtype 1 Receptor (AT1R) Blockade
Cardiac AT(2)R expression is upregulated in the normal process of aging. In this study we determined the contribution of AT(2)R to chronic antihypertensive and remodelling effects of AT(1)R blockade in aged hypertensive rats. Adult (20 weeks) and senescent (20 months) spontaneously hypertensive rats (SHRs) were treated with either the AT(1)R antagonist, candesartan cilexetil (2 mg/kg/day), the ...
متن کاملAngiotensin II-induced renal vasoconstriction in genetic hypertension.
Previous studies demonstrate that renovascular responses to angiotensin II (Ang II) are enhanced in spontaneously hypertensive rats (SHRs); however, it is possible that this hyperresponsiveness is mediated by Ang II-induced release of substances from the adrenal gland. Previous studies also show that pertussis toxin normalizes renovascular responses to Ang II in SHRs; however, it is possible th...
متن کاملAngiotensin II Increased Neuronal Stem Cell Proliferation: Role of AT2R
Angiotensin II (Ang II), known a potent vasoactive substance in the renin-angiotensin system in the brain, plays a critical role in systemic blood pressure control. However, increasing evidence indicated that the physiological role of Ang II go beyond its vasoactive effect. In the present study, we demonstrated that Ang II type-1 receptor (AT1R) and type-2 receptor (AT2R) were expressed in prim...
