Glial Purinergic Signaling in Neurodegeneration [PDF]

Frontiers in Neurology, 2021
Purinergic signaling regulates neuronal and glial cell functions in the healthy CNS. In neurodegenerative diseases, purinergic signaling becomes dysregulated and can affect disease-associated phenotypes of glial cells. In this review, we discuss how cell-specific expression patterns of purinergic signaling components change in neurodegeneration and how

Extracellular ATP released by osteoblasts is a key local inhibitor of bone mineralisation [PDF]

, 2013
Previous studies have shown that exogenous ATP (>1µM) prevents bone formation in vitro by blocking mineralisation of the collagenous matrix. This effect is thought to be mediated via both P2 receptor-dependent pathways and a receptor-independent ...

Purinergic signaling in epilepsy [PDF]

Journal of Neuroscience Research, 2016
Until recently, analysis of the mechanisms underlying epilepsy was centered on neuron dysfunctions. Accordingly, most of the available pharmacological treatments aim at reducing neuronal excitation or at potentiating neuronal inhibition. These therapeutic options can lead to obvious secondary effects, and, moreover, seizures cannot be controlled by any

Electroacupuncture prevents astrocyte atrophy to alleviate depression

Cell Death and Disease, 2023
Astrocyte atrophy is the main histopathological hallmark of major depressive disorder (MDD) in humans and in animal models of depression. Here we show that electroacupuncture prevents astrocyte atrophy in the prefrontal cortex and alleviates depressive ...

P2X7 Receptor–Mediated Inflammation in Cardiovascular Disease

Frontiers in Pharmacology, 2021
Purinergic P2X7 receptor, a nonselective cation channel, is highly expressed in immune cells as well as cardiac smooth muscle cells and endothelial cells.

Prenatal exposure to valproic acid induces alterations in the expression and activity of purinergic receptors in the embryonic rat brain

Folia Neuropathologica, 2022
Purinergic signalling is involved in the control of several processes related to brain development, such as neurogenesis and gliogenesis, migration and differentiation of neuronal precursors, synaptogenesis and synaptic elimination to achieve a fully ...

Red blood cell endothelial nitric oxide synthase: A major player in regulating cardiovascular health

British Journal of Pharmacology, EarlyView., 2023
Abstract Red blood cells (RBCs) have traditionally been seen as simple carriers of gases and nutrients in the body. One important non‐canonical function of RBCs in the cardiovascular system is the regulation of nitric oxide (NO) metabolism. It has been shown that RBCs can scavenge NO, transport NO metabolites and produce NO in hypoxic conditions ...

Purinergic signalling and cancer [PDF]

Purinergic Signalling, 2013
Receptors for extracellular nucleotides are widely expressed by mammalian cells. They mediate a large array of responses ranging from growth stimulation to apoptosis, from chemotaxis to cell differentiation and from nociception to cytokine release, as well as neurotransmission.

Purinergic signalling pathway: therapeutic target in ovarian cancer

Egyptian Journal of Medical Human Genetics, 2020
Background The lack of early diagnostic tools and the development of chemoresistance have made ovarian cancer (OC) one of the deadliest gynaecological cancers.

Purinergic signalling [PDF]

British Journal of Pharmacology, 2006
While there were early papers about the extracellular actions of purines, the role of ATP as a purinergic neurotransmitter in nonadrenergic, noncholinergic nerves in the gut and bladder in 1972 was a landmark discovery, although it met considerable resistance for the next 20 years. In the early 1990s, receptors for purines were cloned: four P1 receptor
