Effects of adjuvant-induced arthritis on the ventral prostate of rats treated with angiotensin AT1 receptor blocker
da Rocha ES, Gomes FC, de Oliveira MR, Bruneto RV, Borges RMR, de Carvalho EP, Angeli-Junior EV, Garcia-Filho GF, Doná JPL, de Oliveira Batanero RP, Carlos CP, de Melo-Neto JS (2020) Effects of adjuvant-induced arthritis on the ventral prostate of rats treated with angiotensin AT1 receptor blocker. Life Sci 252:117629. doi: 10.1016/j.lfs.2020.117629 PMID: 32247619
Objective: To analyze the prostatic compartments, extracellular matrix, microvascularization, transforming growth factor-beta (TGF-β) and angiotensin II receptors type 1 (AT1) levels, and histopathology of the ventral prostate in a rat model for rheumatoid arthritis, and to evaluate the effect of angiotensin II AT1 receptor blocker (ARB) in the disease.
Summary: AIA may activate specific mechanisms that modify the prostatic environment; the use of ARB attenuates some altered prostate parameters in a rat model for arthritis.

Activation of the renin-angiotensin system in high fructose-induced metabolic syndrome.
Kim M, Do GY, Kim I (2020) Activation of the renin-angiotensin system in high fructose-induced metabolic syndrome. Korean J Physiol Pharmacol 24(4):319-328. doi: 10.4196/kjpp.2020.24.4.319 PMID: 32587126
Objective: To investigate the hypothesis that high fructose intake induces activation of the renin-angiotensin systems (RAS), resulting in hypertension and metabolic syndrome.
Summary: High fructose intake increased serum renin, Ang II, triglyceride, and cholesterol levels. High fructose intake increased the expression of angiotensinogen in the liver; angiotensin-converting enzyme in the lungs; and renin, angiotensin II type 1a receptor (AT1aR), and angiotensin II type 1b receptor (AT1bR) in the kidneys. High fructose intake induces activation of RAS, resulting in hypertension and metabolic syndrome.

Summary: Highly glucose-sensitive cells in the ventrolateral medulla send catecholaminergic projections to the PVH. These projections can be selectively destroyed by Anti-DBH-SAP “DSAP” experiments show that catecholaminergic projections from glucose-sensitive cells in the ventrolateral medulla are necessary for all responses to glucoprivation, including increases in epinephrine secretion, glucocorticoid secretion, sex behavior, and food intake.

GRP receptor and AMPA receptor cooperatively regulate itch-responsive neurons in the spinal dorsal horn.
Kiguchi N, Uta D, Ding H, Uchida H, Saika F, Matsuzaki S, Fukazawa Y, Abe M, Sakimura K, Ko MC, Kishioka S (2020) GRP receptor and AMPA receptor cooperatively regulate itch-responsive neurons in the spinal dorsal horn. Neuropharmacology 170:108025. doi: 10.1016/j.neuropharm.2020.108025
Objective: To investigate the mechanisms for the activation of itch-responsive GRPR+ neurons in the spinal dorsal horn (SDH).
Summary: These findings demonstrate that GRP and glutamate cooperatively regulate GRPR+ AMPAR+ neurons in SDH, mediating itch sensation. GRP–GRPR and the glutamate–AMPAR system may play pivotal roles in the spinal transmission of itch in rodents and nonhuman primates.
Usage: Bombesin-SAP and Blank-SAP were administered i.t. (5 μg/5 μl).

Inhibition of ROCK signaling pathway accelerates enteric neural crest cell-based therapy after transplantation in a rat hypoganglionic model
Zhao Y, Ge X, Yu H, Kuil LE, Alves MM, Tian D, Huang Q, Chen X, Hofstra RMW, Gao Y (2020) Inhibition of ROCK signaling pathway accelerates enteric neural crest cell-based therapy after transplantation in a rat hypoganglionic model. Neurogastroenterol Motil 32(9):e13895. doi: 10.1111/nmo.13895 PMID: 32515097
Objective: To test the hypothesis that modulation of extracellular factors during transplantation could promote enteric neural crest cells (ENCCs) proliferation and migration, leading to increased transplantation efficiency.
Summary: Since the RhoA/ROCK pathway is highly involved in cytoskeletal dynamics and neurite growth, this study explored the effect of inhibition of this pathway to improve the success of ENCCs transplantation. inhibition of ROCK increased viable cell number, differentiation, and migration of ENCCs in vitro. Moreover, transplantation of labeled ENCCs into the hypoganglionic model showed enhanced distribution of grafted ENCCs, upon treatment with ROCK inhibitor.
