Cell membrane disruption stimulates cAMP and Ca2+ signaling to potentiate cell membrane resealing in neighboring cells

Biology Open, 2017
Disruption of cellular plasma membranes is a common event in many animal tissues, and the membranes are usually rapidly resealed. Moreover, repeated membrane disruptions within a single cell reseal faster than the initial wound in a protein kinase A (PKA)

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

The 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.

Purinergic Signaling During Immune Cell Trafficking [PDF]

, 2016
Migration and positioning of immune cells is fundamental for their differentiation and recruitment at sites of infection. Besides the fundamental role played by chemokines and their receptors, recent studies demonstrate that a complex network of ...

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

International 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 ...

Mechanisms of astrocytic and microglial purinergic signaling in homeostatic regulation and implications for neurological disease [PDF]

Exploration of Neuroscience
Purinergic signaling, mediated by ATP and adenosine receptors, plays a crucial role in cellular communication and homeostasis within the central nervous system (CNS), particularly by regulating synaptic activity, glial cell functions, and neuroplasticity.

Antipsychotics‐Induced Hyposalivation Mediated by Impaired Salivary Ca2+ Signaling

Oral 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 ...

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

Oral 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

The 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

The 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 ...
