Nutrient‐specific combinatorial secretion of GLP‐1 and neurotransmitters in the enteroendocrine L‐cell line GLUTag

open access: yesThe FEBS Journal, EarlyView.
Enteroendocrine L cells function as chemosensors in the intestine. Using the L‐cell line GLUTag, we show that distinct nutrients trigger different combinations of co‐secretion of GLP‐1 and neurotransmitters: D‐glucose evokes GLP‐1, glutamate, and ATP; L‐glutamine evokes GLP‐1 and glutamate; sucralose and butyrate evoke only GLP‐1.

Synergistic Effects of Bacterial Mimetic and Mechanical Stimulation in Dental Pulp Cell Inflammatory Signalling: A Laboratory Investigation

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Objectives Mechanical and/or microbial stimuli can prompt extracellular ATP release in many cell types, where it acts as an inflammatory mediator to amplify pain signals and inflammation. This study aimed to investigate the synergistic effects of microbial and/or mechanical stimulation on ATP and cytokine release from dental pulp cells (DPCs ...

Antipsychotics‐Induced Hyposalivation Mediated by Impaired Salivary Ca2+ Signaling

open access: yesOral Diseases, EarlyView.
ABSTRACT Objectives Antipsychotic‐induced salivary dysfunction such as hyposalivation is a prevalent clinical challenge that severely compromises oral health and quality of life. Although typical and atypical antipsychotics have their therapeutic target in the central nervous system, their direct molecular mechanisms within the salivary glands remain ...

The cellular distribution of P2X7, P2Y6, and P2Y12 during or after pilocarpine-induced status epilepticus and literature review

open access: yesBrain Circulation
BACKGROUND: When a seizure occurs, the distribution of purine receptors in different cell types at various time points remains poorly understood. Our literature review revealed that P2X7, P2Y6, and P2Y12 are expressed in different cells during epilepsy ...

Purinergic Receptors in Spinal Cord-Derived Ependymal Stem/Progenitor Cells and Their Potential Role in Cell-Based Therapy for Spinal Cord Injury

open access: yesCell Transplantation, 2015
Spinal cord injury (SCI) is a major cause of paralysis with no current therapies. Following SCI, large amounts of ATP and other nucleotides are released by the traumatized tissue leading to the activation of purinergic receptors that, in coordination ...

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

TMEM16A channel signalling microdomains in the regulation of vascular function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...

Possible neuroprotective role of P2X2 in the retina of diabetic rats

open access: yesDiabetology & Metabolic Syndrome, 2018
Background Purinergic receptors are expressed in different tissues including the retina. These receptors are involved in processes like cell growth, proliferation, activation and survival. ATP is the major activator of P2 receptors. In diabetes, there is

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

open access: yesThe 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.
