Genetic Pigmentary Disorders: From Molecular Mechanisms to Clinical Manifestations

The Journal of Dermatology, EarlyView.
ABSTRACT Genetic pigmentary disorders represent a diverse group of genetic conditions characterized by alterations in melanin production and transport and melanocyte development, resulting from single‐gene pathological variants. These disorders encompass both hypopigmentary and hyperpigmentary phenotypes, affecting not only skin pigmentation but also ...

Renal pericytes: regulators of medullary blood flow [PDF]

, 2012
Regulation of medullary blood flow (MBF) is essential in maintaining normal kidney function. Blood flow to the medulla is supplied by the descending vasa recta (DVR), which arise from the efferent arterioles of juxtamedullary glomeruli.

Endothelin ETA- and ETB-Receptor-Mediated Inhibition of Noradrenaline Release From Isolated Rat Stomach

Journal of Pharmacological Sciences, 2003
We examined the effect of endothelin-1, endothelin-3 and sarafotoxin S6c on the release of noradrenaline from gastric sympathetic nerve terminals using an isolated, vascularly perfused rat stomach.

Single oral administration of dronabinol increases ocular blood flow in patients with glaucoma

Acta Ophthalmologica, EarlyView.
Abstract Purpose Glaucoma is a leading cause of irreversible blindness globally, primarily driven by elevated intraocular pressure (IOP). Still, some patients progress despite significant IOP lowering, potentially due to impaired ocular blood flow. This study aimed to evaluate the effects of dronabinol, a synthetic tetrahydrocannabinol derivative, on ...

Endothelin

Pharmacological Reviews, 2016
The endothelins comprise three structurally similar 21-amino acid peptides. Endothelin-1 and -2 activate two G-protein coupled receptors, ETA and ETB, with equal affinity, whereas endothelin-3 has a lower affinity for the ETA subtype.

Vessel‐associated microglia are differentially activated and distributed in relation to systemic infection and Alzheimer's disease

Brain Pathology, EarlyView.
This post‐mortem study revealed an increased density of vessel‐associated microglia (VAM) in the temporal lobe in systemic infection and Alzheimer's disease. VAM density was related to brain cytokine levels and markers of cerebrovascular dysfunction and BBB leakage indicating that activated VAM contributes to neurovascular injury in Alzheimer's disease.
