Purinergic Signaling in Spermatogenesis

open access: yesFrontiers in Endocrinology, 2022
Adenosine triphosphate (ATP) serves as the essential source of cellular energy. Over the last two decades, however, ATP has also attracted increasing interest as an extracellular signal that activates purinergic plasma membrane receptors of the P2 family.

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

open access: yesFolia 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 ...

Purinergic signalling pathway: therapeutic target in ovarian cancer

open access: yesEgyptian 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.

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

open access: yes, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Early evolutionary history (from bacteria to hemichordata) of the omnipresent purinergic signalling: A tribute to geoff burnstock inquisitive mind.

open access: yesBiochemical Pharmacology, 2020
Purines and pyrimidines are indispensable molecules of life; they are fundamental for genetic code and bioenergetics. From the very early life forms purines have acquired the meaning of damage-associated extracellular signaller and purinergic receptors ...

Transient signal generation in a self-assembled nanosystem fueled by ATP [PDF]

open access: yes, 2015
A fundamental difference exists in the way signal generation is dealt with in natural and synthetic systems. While nature uses the transient activation of signalling pathways to regulate all cellular functions, chemists rely on sensory devices that ...

Evolutionary origins of taste buds: phylogenetic analysis of purinergic neurotransmission in epithelial chemosensors [PDF]

open access: yesOpen Biology, 2013
Taste buds are gustatory endorgans which use an uncommon purinergic signalling system to transmit information to afferent gustatory nerve fibres. In mammals, ATP is a crucial neurotransmitter released by the taste cells to activate the afferent nerve ...

Biosensor measurement of purine release from cerebellar cultures and slices [PDF]

open access: yes, 2010
We have previously described an action-potential and Ca2+-dependent form of adenosine release in the molecular layer of cerebellar slices. The most likely source of the adenosine is the parallel fibres, the axons of granule cells. Using microelectrode

Purinergic signalling in systemic sclerosis

open access: yesRheumatology, 2021
Abstract SSc is a chronic autoimmune rheumatic disease that involves numerous organs and presents major management challenges. The histopathologic hallmarks of SSc include vasculopathy, fibrosis and autoimmune phenomena involving both innate and adaptive immune systems.

Purinergic Signaling in Bone [PDF]

open access: yesJournal of Osteoporosis, 2013
In recent years, it has become apparent that extracellular nucleotides, signalling via P2 receptors, play an important role in the regulation of bone turnover. Furthermore, purinergic signalling has been associated in the pathophysiology of several bone and cartilage diseases, including osteoarthritis, rheumatoid arthritis, and osteoporosis and might ...
