Real-time patch-cram detection of intracellular cGMP reveals long-term suppression of responses to NO and muscarinic agonists.

Neuron, 1998
Cyclic GMP (cGMP) is a crucial intracellular messenger in neuronal, muscle, and endocrine cells. The intracellular concentration of cGMP is regulated by various neurotransmitters, including acetylcholine (ACh) and nitric oxide (NO).

A role for epithelium‐derived 6‐nitrodopamine on human ureter contractility

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose To investigate the basal release of 6‐nitrodopamine (6‐ND) from human isolated ureter and the role of this novel catecholamine in the ureter contractility. Experimental Approach Ureters from 67 brain‐dead organ donors (40 males and 27 females) were used during kidney transplantation procedures.

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

, 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.

Novel drugs approved by the EMA, the FDA and the MHRA in 2025: A year in review

British Journal of Pharmacology, EarlyView.
Abstract In the 2025 novel drug mini‐review, one can take a full measure of the ingenuity that underlies current drug design and development, despite the year's smaller harvest (46 novel drugs) compared to 2024 (53) and 2023 (70). 54% of the novel drugs are first‐in‐class (FIC).

Pharmacological modulation of fish-induced depth selection in D. magna: the role of cholinergic and GABAergic signalling

Scientific Reports, 2021
Animal behaviour is closely related to individual fitness, which allows animals to choose suitable mates or avoid predation. The central nervous system regulates many aspects of animal behaviour responses.

Presynaptic M1 muscarinic cholinoceptors mediate inhibition of excitatory synaptic transmission in the hippocampus in vitro [PDF]

, 1990
The effects of the cholinoceptor agonist, carbachol (CCh), were examined in the rat hippocampal slice preparation. Intracellular recordings from CA1 pyramidal neurones revealed that CCh (1–3 μM) inhibited excitatory postsynaptic responses evoked by ...

Spreading depolarization and its influence on epileptiform activity

Epilepsia, EarlyView.
Abstract Spreading depolarization (SD) is a transient disruption of electrographic activity that slowly propagates through the gray matter by chemical contiguity, and it is characterized by a large depolarization of neurons and glial cells. SD, which is associated with massive changes in ion homeostasis, including extreme increases in [K+]o, was shown ...

Association Between Cholinesterase Inhibitor‐Overactive Bladder Antimuscarinic Prescribing Cascade and Risk of Delirium and Falls Among Individuals Living With Dementia

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Prescribing cascades occur when cholinesterase inhibitor (ChEI)‐induced urinary incontinence is misinterpreted as a new condition, leading to overactive bladder (OAB) antimuscarinic initiation. We evaluated whether the ChEI‐OAB antimuscarinic prescribing cascade was associated with delirium or falls compared with mirabegron in older

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...
