Ion Channel Dysfunction and Neuroinflammation in Migraine and Depression

Frontiers in Pharmacology, 2021
Migraine and major depression are debilitating disorders with high lifetime prevalence rates. Interestingly these disorders are highly comorbid and show significant heritability, suggesting shared pathophysiological mechanisms.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Cryo-EM structures of pannexin 1 and 3 reveal differences among pannexin isoforms

Nature Communications
Pannexins are single-membrane large-pore channels that release ions and ATP upon activation. Three isoforms of pannexins 1, 2, and 3, perform diverse cellular roles and differ in their pore lining residues.

Intercellular odontoblast communication via ATP mediated by pannexin-1 channel and phospholipase C-coupled receptor activation.

Frontiers in Physiology, 2015
Extracellular ATP released via pannexin-1 channels, in response to the activation of mechanosensitive-TRP channels during odontoblast mechanical stimulation, mediates intercellular communication among odontoblasts in dental pulp slice preparation ...

Adaptive thermogenesis in brown adipose tissue involves activation of pannexin-1 channels

Molecular Metabolism, 2021
Objective: Brown adipose tissue (BAT) is specialized in thermogenesis. The conversion of energy into heat in brown adipocytes proceeds via stimulation of β-adrenergic receptor (βAR)-dependent signaling and activation of mitochondrial uncoupling protein 1

Targeting inflammation in cardiometabolic disease: Icosapent ethyl modulates monocyte‐derived macrophages isolated from patients with cardiovascular disease with or without type 2 diabetes

Diabetic Medicine, Volume 43, Issue 4, April 2026.
Abstract Aims Despite intensive lipid‐lowering therapy, individuals with atherosclerotic cardiovascular disease (ASCVD) exhibit residual inflammatory risk, which drives recurrent cardiovascular events. This risk is amplified in type 2 diabetes mellitus (T2DM), where a pro‐inflammatory milieu accelerates atherogenesis. Monocyte‐derived macrophages (MDMs)

Mechanistic insights into severe pulmonary inflammation caused by silica stimulation: The role of macrophage pyroptosis

Ecotoxicology and Environmental Safety, 2023
Respirable silica dust is a common hazard faced by occupational workers and prolonged exposure to this dust can lead to pulmonary inflammation, fibrosis and, in severe cases, silicosis.

Astrocyte Bioenergetic Remodeling as a Central Trait of Disrupted Glucocorticoid Signaling: Mechanisms and Implications for Stress Vulnerability

Journal of Neurochemistry, Volume 170, Issue 3, March 2026.
Low/brief glucocorticoid (GC) elevations can enhance mitochondrial output (↑ oxygen consumption rate, OCR; ↑ mitochondrial membrane potential, ΔΨm) and Ca2+ buffering, in part via glucocorticoid receptor (GR) trafficking to mitochondria in complexes with Bcl2 and Bag1.

Control of the neurovascular coupling by nitric oxide-dependent regulation of astrocytic Ca2+ signaling

Frontiers in Cellular Neuroscience, 2015
Neuronal activity must be tightly coordinated with blood flow to keep proper brain function, which is achieved by a mechanism known as neurovascular coupling. Then, an increase in synaptic activity leads to a dilation of local parenchymal arterioles that
