Effect of chronic intermittent hypoxia on angiotensin II receptors in the central nervous system
Morgan BJ, Schrimpf N, Rothman M, Mitzey A, Brownfield MS, Speth RC, Dopp JM (2018) Effect of chronic intermittent hypoxia on angiotensin II receptors in the central nervous system. Clin Exp Hypertens 41:1-7. doi: 10.1080/10641963.2018.1451536 PMID: 29561178
Objective: To quantify the effects of chronic intermittent hypoxia (CIH) on AT1R- and AT2R-like immunoreactivity in the rostroventrolateral medulla (RVLM) and paraventricular nucleus of the hypothalamus (PVN), central regions that are important components of the extended chemoreflex pathway.
Summary: Exposure to CIH of at least 5 days duration augmented AT1R-like immunoreactivity in RVLM. In contrast, CIH exposure did not affect AT2R-like reactivity in RVLM or that of either Ang II receptor subtype in PVN.
Usage: Immunoreactivity, immunostaining. For immunoreactivity assays, antibodies were diluted in the blocking solution with 0.05% sodium azide at the following concentrations: AT-1R, (1:1600) and AT-2R, (1:5000).

Objective: To determine the role of somatostatin in itch and pain.
Summary: Results define the neural circuit underlying somatostatin-induced itch and characterize a contrasting antinociceptive role for the peptide.

Combinatorial effects of alpha- and gamma-protocadherins on neuronal survival and dendritic self-avoidance
Ing-Esteves S, Kostadinov D, Marocha J, Sing AD, Joseph KS, Laboulaye MA, Sanes JR, Lefebvre JL (2018) Combinatorial effects of alpha- and gamma-protocadherins on neuronal survival and dendritic self-avoidance. J Neurosci 38:2713-2729. doi: 10.1523/JNEUROSCI.3035-17.2018 PMID: 29439167
Objective: The clustered protocadherins (Pcdhs) comprise 58 cadherin-related proteins encoded by three tandemly arrayed gene clusters, Pcdh- , Pcdh- , and Pcdh- (Pcdha, Pcdhb, and Pcdhg, respectively). This study sought to determine roles of Pcdhas and Pcdhgs in the retina and cerebellum from mice (both sexes) lacking one or both clusters.
Summary: Study examined two regions of the CNS, the retina and cerebellum and showed that the 14 -Pcdhs and 22 -Pcdhs act synergistically to mediate neuronal survival and dendrite patterning. In retina, Pcdhgs are essential for survival of inner retinal neurons and dendritic self-avoidance of starburst amacrine cells, whereas Pcdhas are dispensable for both processes.
Usage: Anti-Melanopsin (1:5000) used to quantify two mutually exclusive RGC cell types, the Brn3a RGCs and the melanopsin-positive intrinsically photo- sensitive RGCs (Mel ipRGCs).

Induced pluripotent stem cells with NOTCH1 gene mutation show impaired differentiation into smooth muscle and endothelial cells: Implications for bicuspid aortic valve-related aortopathy
Jiao J, Tian W, Qiu P, Norton EL, Wang MM, Chen YE, Yang B (2018) Induced pluripotent stem cells with NOTCH1 gene mutation show impaired differentiation into smooth muscle and endothelial cells: Implications for bicuspid aortic valve-related aortopathy. J Thorac Cardiovasc Surg 156:515-522. doi: 10.1016/j.jtcvs.2018.02.087 PMID: 29653750
Objective: To develop an in vitro model with human-induced pluripotent stem cells (iPSCs) to evaluate the role of NOTCH1 in smooth muscle and endothelial cell differentiation.
Summary: NOTCH1 is critical in SMC and EC differentiation of iPSCs through neural crest stem cells and cardiovascular progenitor cells, respectively. NOTCH1gene mutations may potentially contribute to the development of thoracic aortic aneurysms by affecting SMC differentiation in some patients with bicuspid aortic valve-related aortopathy.
Usage: Immunofluorescence staining and flow cytometry was performed.
