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

open access: yesActa 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

open access: yesBrain 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.

Cooperation of endothelin-1 signaling with melanosomes plays a role in developing and/or maintaining human skin hyperpigmentation

open access: yesBiology Open, 2015
Skin hyperpigmentation is characterized by increased melanin synthesis and deposition that can cause significant psychosocial and psychological distress.

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

open access: yesBrain 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 ...

Smoking particles enhance endothelin A and endothelin B receptor-mediated contractions by enhancing translation in rat bronchi

open access: yesBMC Pulmonary Medicine, 2006
Background Smoking is known to cause chronic inflammatory changes in the bronchi and to contribute to airway hyper-reactivity, such as in bronchial asthma.

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

open access: yesBritish 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.

Secondhand smoke exposure induces Raf/ERK/MAPK-mediated upregulation of cerebrovascular endothelin ETA receptors

open access: yesBMC Neuroscience, 2011
Background Cigarette smoking enhances the risk of stroke. However, the underlying molecular mechanisms are largely unknown. The present study established an in vivo rat secondhand cigarette smoking (SHS) model and examined the hypothesis that SHS ...
