A novel subtype of endothelin receptors.

Journal of Biological Chemistry, 1992
A new subtype of endothelin receptors with binding properties typical of "super-high" affinity sites, i.e. with affinities in the picomolar range, were identified and characterized in several rat brain regions and atrium. The pharmacological profile of these sites is indicative of the endothelin receptor type B (ETB-R).

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 ...

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

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 ...

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.

Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

Brain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

British Journal of Pharmacology, EarlyView.
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.

TNF‐α partially modulates the endothelial dysfunction during the acute phase of Trypanosoma cruzi infection

British Journal of Pharmacology, EarlyView.
Background and Purpose Whereas the effects of Trypanosoma cruzi (T. cruzi) infection are well‐characterised in the heart, its impact on the vasculature has received little attention. In this study, we investigated the effects of acute and chronic T. cruzi infection on vascular responsiveness and the underlying mechanisms.
