Angiotensin II receptor

Liu H, Xue Y, Chen L (2022) Angiotensin II increases the firing activity of pallidal neurons and participates in motor control in rats. Metab Brain Dis 38:573-587. doi: 10.1007/s11011-022-01127-w PMID: 36454502

Objective: To investigate the functions of angiotensin II (Ang II)/angiotensin subtype 1 receptor (AT1R) on the globus pallidus neurons of both normal and Parkinsonian rats.

Summary: The authors conclude that pallidal Ang II/AT1R alleviated Parkinsonian motor deficits by activating globus pallidus neurons. This provides a rationale for further investigations into the potential of Ang II for treating motor disorders originating from the basal ganglia.

Usage: Coronal Sections (40 μm) containing the globus pallidus were blocked with 5% BSA and 0.3% Triton X-100 in PBS for 45 min and subsequently incubated with AT1R antibody (AB-N27AP) for 48 h at 4°.

Objective: To determine the role of angiotensin converting enzyme 2 (ACE2) as the receptor for SARS-CoV-2 entry, is also an important regulator of renin-angiotensin system (RAS) homeostasis, which plays an unsettled role in the pathogenesis of COVID-19.

Summary: The downregulation of ACE2 potentially links COVID-19 to the imbalance of RAS.

Objective: To identify angiotensin (Ang) II as a positive regulator of Group 2 innate lymphoid cells (ILC2s).

Summary: Ang II plays a critical role in regulating ILC2 responses and airways inflammation.

Usage: Administration of Ang II (30ug) i.n. or i.p. daily for 5 days.

Kim HS, Kim HY (2022) Hypertensive effects of transforming growth factor-β1 in vascular smooth muscles cells from spontaneously hypertensive rats are mediated by sulfatase 2. Cytokine 150:155754. doi: 10.1016/j.cyto.2021.155754 PMID: 34808537

Objective: To examine the role of extracellular sulfatases on TGF-β1-induced effects associated with the expression of mediators related to hypertension in vascular smooth muscle cells (VSMCs) from spontaneously hypertensive rats (SHR).

Summary: The hypertensive effects of TGF-β1 through the AT1 R pathway were mainly dependent on Sulf2 activity in SHR VSMCs. Taken together, these results suggest that Sulf2, but not Sulf1, plays a major role in mediating the increased effects of TGF-β1 in hypertensive VSMCs.
