Metabolic Coordination of Pericyte Phenotypes: Therapeutic Implications [PDF]
Frontiers in Cell and Developmental Biology, 2020 Pericytes are mural vascular cells found predominantly on the abluminal wall of capillaries, where they contribute to the maintenance of capillary structural integrity and vascular permeability. Generally quiescent cells in the adult, pericyte activation

Differential pericyte pathology in the human retina and brain in diabetes mellitus and Alzheimer’s disease [PDF]
Frontiers in NeuroscienceIntroductionIn diabetic retinopathy, pericyte dysfunction, pericyte loss, and inner blood–retinal barrier (iBRB) dysfunction contribute to neurovascular unit (NVU) impairment.

MicroRNA210 regulated brain pericyte dysfunction exacerbates hypoxic-ischemic brain injury in neonatal mice [PDF]
Fluids and Barriers of the CNSBackground While the role of pericytes in blood-brain barrier (BBB) disruption and neuroinflammation is well-established in adult neurological disorders, their contribution to neonatal brain injury is largely unexplored. Here, we investigated the role of

In vivo Single Cell Optical Ablation of Brain Pericytes
Frontiers in Neuroscience, 2022 Pericytes have myriad functions in cerebrovascular regulation but remain understudied in the living brain. To dissect pericyte functions in vivo, prior studies have used genetic approaches to induce global pericyte loss in the rodent brain. However, this

Nature Communications, 2022 Using in vivo two-photon imaging, Berthiaume et al. demonstrate how pericyte loss during aging could contribute to deterioration of cerebral blood flow. They also show how pericyte remodeling reduces the deleterious effects of pericyte loss.

Early vessel destabilization mediated by Angiopoietin-2 and subsequent vessel maturation via Angiopoietin-1 induce functional neovasculature after ischemia. [PDF]
, 2013 We assessed whether Angiopoietin-2 (Ang2), a Tie2 ligand and partial antagonist of Angiopoietin-1 (Ang1), is required for early vessel destabilization during postischemic angiogenesis, when combined with vascular growth factors.

Mechanism of retinal pericyte migration through Angiopoietin/Tie-2 signaling pathway on diabetic rats [PDF]
International Journal of Ophthalmology, 2018 AIM: To investigate the mechanism of pericyte migration through Angiopoietin-2 (Ang-2)/Tie-2 signaling pathway. METHODS: We divided the rats into 5 groups. Each diabetic rat model groups injected with Tie-2 inhibitor, ERK1/2 inhibitor, Akt/PKB inhibitor,
