Effects of antidepressants on P2X7 receptors
Psychiatry Research, 2016Antidepressants including paroxetine, fluoxetine and desipramine are commonly used for treating depression. P2×7 receptors are member of the P2X family. Recent studies indicate that these receptors may constitute a novel potential target for the treatment of depression. In the present study, we examined the action of these antidepressants on cloned rat

The P2X7 receptor is a trimeric ion channel gated by extracellular adenosine 5'-triphosphate. The receptor is present on an increasing number of different cells types including stem, blood, glial, neural, ocular, bone, dental, exocrine, endothelial, muscle, renal and skin cells.

P2X7 Receptor as a Therapeutic Target
2016P2X7 receptor is an ATP-gated cation channel that upon agonist interaction leads to cellular influx of Na(+) and Ca(2+) and efflux of K(+). P2X7 is expressed by a wide variety of cells and its activation mediates a large number of biological processes like inflammation, neuromodulation, cell death or cell proliferation and it has been associated to ...

Analyzing the Role of the P2X7 Receptor in Epilepsy
2022Purinergic signaling is increasingly recognized to play a role during the generation of hyperexcitable networks in the brain. Among the purinergic receptors, the ionotropic ATP-gated P2X7 receptor has attracted particular attention as a possible drug target for epilepsy.

Regulation of Immune Response by P2X7 Receptor
Critical Reviews™ in Immunology, 2006The P2X7 receptor is an ATP-gated cation channel that is widely expressed in cells of the immune system. Signal transduction is accompanied by fast influx of Ca2+ and Na+, and efflux of K+. This receptor differs from other members of the P2X family in its relatively low affinity for ATP, the presence of a long C-terminal region that contains several ...

Molecular Probes for P2X7 Receptor Studies
Current Medicinal Chemistry, 2007The ionotropic P2X7 receptor (P2X7R) has become the focus of intense research interest for a number of reasons: i) it is a cation selective ion channel that is modulated by extracellular ATP. Upon stimulation by high concentrations of ATP it generates a non-selective membrane pore which is permeable to hydrophilic molecules with molecular weight up to ...

The role of microglia and P2X7 receptors in gliomas
Journal of Neuroimmunology, 2019Gliomas are the most prevalent tumours of the central nervous system and present with high morbidity and mortality. The most common and most aggressive form of glioma is glioblastoma multiforme, of which patients have a median survival time of only 12 to 15 months.

Recently, one of the P2 purinergic receptors, the P2X(7) receptor, has been extensively studied in nervous system and important functions have been revealed in both astrocytes and microglia. Stimulation of the receptors induces a sustained and nondesensitized increase in intracellular Ca(2+) concentration ([Ca(2+)](i)).

Antidepressants as modulators of P2X7 receptor activity
NeuroscienceAccording to the Pan American Health Organization, more than 300 million people suffer from depression worldwide. Despite the alarming numbers, current drug treatments produce partial results, as they focus on only one pillar of depression: neurotransmitters.
