Highly potent, selective acylguanidine-type histamine H2 receptor agonists: synthesis and structure-activity relationships [PDF]

open access: yes, 2008
Potent and selective histamine H2 receptor (H2R) agonists are valuable pharmacological tools and might be of therapeutic value as drugs, for example in the treatment of severe congestive heart failure.

Human Adenosine A2A Receptor: Molecular Mechanism of Ligand Binding and Activation

open access: yesFrontiers in Pharmacology, 2017
Adenosine receptors (ARs) comprise the P1 class of purinergic receptors and belong to the largest family of integral membrane proteins in the human genome, the G protein-coupled receptors (GPCRs).

Adenosine-mediated modulation of ventral horn interneurons and spinal motoneurons in neonatal mice [PDF]

open access: yes, 2015
The authors are grateful for support from the Wellcome Trust.Neuromodulation allows neural networks to adapt to varying environmental and biomechanical demands. Purinergic signalling is known to be an important modulatory system in many parts of the CNS,

CiD agonists: Circular DNA-based agonists for the fine-tuning of receptor signaling [PDF]

open access: yes, 2022
Receptor dimerization geometry plays a significant role in signal transduction induced by growth factors and cytokines. A chemical strategy capable of controlling dimerization geometry provides a means for studying receptor activation mechanisms and ...

Purines as potential morphogens during embryonic development [PDF]

open access: yes, 2012
Components of purinergic signalling are expressed in the early embryo raising the possibility that ATP, ADP and adenosine may contribute to the mechanisms of embryonic development.

The relationship between P2X4 and P2X7: a physiologically important interaction? [PDF]

open access: yes, 2013
Purinergic signaling within the kidney is becoming an important focus in the study of renal health and disease. The effectors of ATP signaling, the P2Y and P2X receptors, are expressed to varying extents in and along the nephron.

Adenosine—A Regulator of Human Testicular Peritubular Cells

open access: yesAndrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Purinergic signalling: past, present and future [PDF]

open access: yes, 2009
The discovery of non-adrenergic, non-cholinergic neurotransmission in the gut and bladder in the early 1960's is described as well as the identification of adenosine 5'-triphosphate (ATP) as a transmitter in these nerves in the early 1970's.

Exocytosis of ATP from astrocytes modulates phasic and tonic inhibition in the neocortex [PDF]

open access: yes, 2014
Communication between neuronal and glial cells is important for many brain functions. Astrocytes can modulate synaptic strength via Ca2+-stimulated release of various gliotransmitters, including glutamate and ATP. A physiological role of ATP release from

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora
