Ketones prevent oxidative impairment of hippocampal synaptic integrity through KATP channels.

PLoS ONE, 2015
Dietary and metabolic therapies are increasingly being considered for a variety of neurological disorders, based in part on growing evidence for the neuroprotective properties of the ketogenic diet (KD) and ketones.

ATP-gated potassium channels contribute to ketogenic diet-mediated analgesia in mice

Neurobiology of Pain, 2023
Chronic pain is a substantial health burden and options for treating chronic pain remain minimally effective. Ketogenic diets are emerging as well-tolerated, effective therapeutic strategies in preclinical models of chronic pain, especially diabetic ...

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.

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Expression of ATP-sensitive potassium channels in human pregnant myometrium

Reproductive Biology and Endocrinology, 2011
Background Potassium channels play critical roles in the regulation of cell membrane potential, which is central to the excitability of myometrium. The ATP-sensitive potassium (KATP) channel is one of the most abundant potassium channels in myometrium ...

Lactate activation of α-cell KATP channels inhibits glucagon secretion by hyperpolarizing the membrane potential and reducing Ca2+ entry

Molecular Metabolism, 2020
Objective: Elevations in pancreatic α-cell intracellular Ca2+ ([Ca2+]i) lead to glucagon (GCG) secretion. Although glucose inhibits GCG secretion, how lactate and pyruvate control α-cell Ca2+ handling is unknown.

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

Traffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

Role of KATP channels in angiogenesis [PDF]

, 2021
Σε πολλά εργαστήρια, σε παγκόσμιο επίπεδο, συντελείται σημαντική ερευνητική προσπάθεια για την ταυτοποίηση νέων μοριακών μηχανισμών στο πεδίο της αγγειογένεσης ως στόχων ανάπτυξης φαρμάκων, καθώς η θεραπευτική ρύθμιση της αγγειογένεσης μπορεί να επηρεάσει σημαντικά την εξέλιξη πολλών ασθενειών.
