Neurobiology of Disease, 2018 Background: Cerebrovascular dysfunction and inflammation occur in epilepsy. Here we asked whether pericytes, a pivotal cellular component of brain capillaries, undergo pathological modifications during experimental epileptogenesis and in human epilepsy ...

Effects of the histone deacetylase inhibitor valproic acid on human pericytes in vitro. [PDF]
PLoS ONE, 2011 Microvascular pericytes are of key importance in neoformation of blood vessels, in stabilization of newly formed vessels as well as maintenance of angiostasis in resting tissues.

Metabolic Stress Impairs Pericyte Response to Optogenetic Stimulation in Pancreatic Islets
Frontiers in Endocrinology, 2022 Pancreatic islets are highly vascularized micro-organs ensuring whole body glucose homeostasis. Islet vascular cells play an integral part in sustaining adequate insulin release by beta cells.

Age and diabetes related changes of the retinal capillaries: an ultrastructural and immunohistochemical study [PDF]
, 2015 Normal human aging and diabetes are associated with a gradual decrease of cerebral flow in the brain with changes in vascular architecture. Thickening of the capillary basement membrane and microvascular fibrosis are evident in the central nervous system

The blood labyrinthine barrier in the human normal and Meniere's disease macula utricle. [PDF]
, 2017 The ultrastructural organization of the blood labyrinthine barrier (BLB) was investigated in the human vestibular endorgan, the utricular macula, using postmortem specimens from individuals with documented normal auditory and vestibular function and ...

Diabetes, 2008 OBJECTIVE— The mechanism underlying pericyte loss during incipient diabetic retinopathy remains controversial. Hyperglycemia induces angiopoietin-2 (Ang-2) transcription, which modulates capillary pericyte coverage. In this study, we assessed loss of pericyte subgroups and the contribution of Ang-2 to pericyte migration.

Pericyte mechanics and mechanobiology [PDF]
Journal of Cell Science, 2021 ABSTRACT Pericytes are mural cells of the microvasculature, recognized by their thin processes and protruding cell body. Pericytes wrap around endothelial cells and play a central role in regulating various endothelial functions, including angiogenesis and inflammation.
