ATP as a Multi-target Danger Signal in the Brain

open access: yesFrontiers in Neuroscience, 2015
ATP is released in an activity-dependent manner from different cell types in the brain, fulfilling different roles as a neurotransmitter, neuromodulator, astrocyte-to-neuron communication, propagating astrocytic responses and formatting microglia ...

5-Hydroxytryptamine, Glutamate, and ATP: Much More Than Neurotransmitters

open access: yesFrontiers in Cell and Developmental Biology, 2021
5-hydroxytryptamine (5-HT) is derived from the essential amino acid L-tryptophan. Although the compound has been studied extensively for its neuronal handling and synaptic actions, serotonin 5-HT receptors can be found extra-synaptically and not only in ...

Dinucleoside polyphosphates : newly detected uraemic compounds with an impact on leucocyte oxidative burst [PDF]

open access: yes, 2009
Background. Dinucleoside polyphosphates (NpnN) have pathophysiologic roles in cardiovascular disease and are newly detected uraemic retention solutes. They were retrieved in human plasma, tissues and cells.

Emerging roles of purinergic signaling in anti-cancer therapy resistance

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cancer is a complex disease with a rapid growing incidence and often characterized by a poor prognosis. Although impressive advances have been made in cancer treatments, resistance to therapy remains a critical obstacle for the improvement of patients ...

Purinergic signaling in the modulation of redox biology

open access: yesRedox Biology, 2021
Purinergic signaling is a cell communication pathway mediated by extracellular nucleotides and nucleosides. Tri- and diphosphonucleotides are released in physiological and pathological circumstances activating purinergic type 2 receptors (P2 receptors ...

Transmission to interneurons is via slow excitatory synaptic potentials mediated by P2Y(1) receptors during descending inhibition in guinea-pig ileum. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: The nature of synaptic transmission at functionally distinct synapses in intestinal reflex pathways has not been fully identified. In this study, we investigated whether transmission between interneurons in the descending inhibitory pathway ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

ATP- and Adenosine-Mediated Signaling in the Central Nervous System: Adenosine Receptor Activation by ATP Through Rapid and Localized Generation of Adenosine by Ecto-nucleotidases

open access: yesJournal of Pharmacological Sciences, 2004
Extracellular ATP is now recognized as a neurotransmitter or neuromodilator in the nervous system, producing diverse physiological effects by activating multiple P2 receptors.

Segregation of receptor-ligand complexes in cell adhesion zones: Phase diagrams and role of thermal membrane roughness

open access: yes, 2010
The adhesion zone of immune cells, the 'immunological synapse', exhibits characteristic domains of receptor-ligand complexes. The domain formation is likely caused by a length difference of the receptor-ligand complexes, and has been investigated in ...

P2 receptors: new potential players in atherosclerosis [PDF]

open access: yesBritish Journal of Pharmacology, 2002
Atherosclerosis is a focal inflammatory disease of the arterial wall. It starts with the formation of fatty streaks on the arterial wall that evolve to form a raised plaque made of smooth muscle cells (SMCs), and infiltrating leukocytes surrounding a necrotic core.
