Ultrastructure of neurovascular changes in human diabetic retinopathy [PDF]

open access: yes, 2018
The previous concept regarding diabetic retinopathy assigned a primary role to hyperglycemia-induced microvascular alterations, while neuronal and glial abnormalities were considered to be secondary to either ischemia or exudation.

Pericytes synthesize renin

open access: yesWorld Journal of Nephrology, 2013
To investigate renin expression in pericytes during normal kidney development and after deletion of angiotensinogen, the precursor for all angiotensins.We examined the distribution of renin expressing cells by immunoshistochemistry in the interstitial compartment of wild type (WT) and angiotensinogen deficient (AGT -/-) mice at different developmental ...

Pericytes modulate endothelial sprouting [PDF]

open access: yesCardiovascular Research, 2013
Angiogenic sprouts arise from microvessels formed by endothelial cells (ECs) invested by pericytes (PCs). The aim of this study was to examine the role of PCs in angiogenic sprouting, an understudied phenomenon.We adapted a human EC spheroid model to examine PC effects on vascular endothelial growth factor-A-induced EC sprouting in vitro by using Bcl-2-

Barrier mechanisms in neonatal stroke. [PDF]

open access: yes, 2014
Clinical data continue to reveal that the incidence of perinatal stroke is high, similar to that in the elderly. Perinatal stroke leads to significant morbidity and severe long-term neurological and cognitive deficits, including cerebral palsy ...

Monitoring imatinib decreasing pericyte coverage and HIF-1α level in a colorectal cancer model by an ultrahigh-field multiparametric MRI approach

open access: yesJournal of Translational Medicine
Background Excessive pericyte coverage promotes tumor growth, and a downregulation may solve this dilemma. Due to the double-edged sword role of vascular pericytes in tumor microenvironment (TME), indiscriminately decreasing pericyte coverage by imatinib

Brain pericytes upregulate glutamate uptake by astrocytes in vitro through sodium-dependent transporter

open access: yesIBRO Neuroscience Reports
Astrocytes maintain glutamate homeostasis in the central nervous system (CNS) via glutamate uptake through Na+-dependent excitatory amino acid transporters (EAAT1 and EAAT2), and this process is regulated by several CNS cell types. However, it is unclear

Dynamic Remodeling of Pericytes In Vivo Maintains Capillary Coverage in the Adult Mouse Brain

open access: yesCell Reports, 2018
Summary: Direct contact and communication between pericytes and endothelial cells is critical for maintenance of cerebrovascular stability and blood-brain barrier function.

Acute Ablation of Cortical Pericytes Leads to Rapid Neurovascular Uncoupling

open access: yesFrontiers in Cellular Neuroscience, 2020
Pericytes are perivascular mural cells that enwrap brain capillaries and maintain blood-brain barrier (BBB) integrity. Most studies suggest that pericytes regulate cerebral blood flow (CBF) and oxygen delivery to activated brain structures, known as ...

Cellular deconvolution of GTEx tissues powers discovery of disease and cell-type associated regulatory variants. [PDF]

open access: yes, 2020
The Genotype-Tissue Expression (GTEx) resource has provided insights into the regulatory impact of genetic variation on gene expression across human tissues; however, thus far has not considered how variation acts at the resolution of the different cell ...

Current Perspective on the Location and Function of Gamma- Aminobutyric Acid (GABA) and its Metabolic Partners in the Kidney. [PDF]

open access: yes, 2014
Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter located in the mammalian central nervous system, which binds to GABAA and GABAB receptors to mediate its neurological effects.
