HL-1 cells express an inwardly rectifying K+ current activated via muscarinic receptors comparable to that in mouse atrial myocytes [PDF]

open access: yes, 2010
An inwardly rectifying K^+ current is present in atrial cardiac myocytes that is activated by acetylcholine (I_{KACh}). Physiologically, activation of the current in the SA node is important in slowing the heart rate with increased parasympathetic tone ...

Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

A Cholinergic Synaptically Triggered Event Participates in the Generation of Persistent Activity Necessary for Eye Fixation [PDF]

open access: yes, 2004
An exciting topic regarding integrative properties of the nervous system is how transient motor commands or brief sensory stimuli are able to evoke persistent neuronal changes, mainly as a sustained, tonic action potential firing.

Multitargeting nature of muscarinic orthosteric agonists and antagonists

open access: yesFrontiers in Physiology, 2022
Muscarinic receptors (mAChRs) are typical members of the G protein-coupled receptor (GPCR) family and exist in five subtypes from M1 to M5. Muscarinic receptor subtypes do not sufficiently differ in affinity to orthosteric antagonists or agonists ...

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

open access: yes, 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 ...

Pro-inflammatory mechanisms of muscarinic receptor stimulation in airway smooth muscle

open access: yesRespiratory Research, 2010
Background Acetylcholine, the primary parasympathetic neurotransmitter in the airways, plays an important role in bronchoconstriction and mucus production.

DREADD Agonist 21 Is an Effective Agonist for Muscarinic-Based DREADDs in Vitro and in Vivo

open access: yesACS Pharmacology & Translational Science, 2018
Chemogenetic tools such as designer receptors exclusively activated by designer drugs (DREADDs) are routinely used to modulate neuronal and non-neuronal signaling and activity in a relatively noninvasive manner.

Spatial intensity distribution analysis: studies of G Protein-coupled receptor oligomerization [PDF]

open access: yes, 2018
Spatial intensity distribution analysis (SpIDA) is a recently developed approach for determining quaternary structure information on fluorophore-labelled proteins of interest in situ. It can be applied to live or fixed cells and native tissue.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

open access: yesBMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Cholinergic partition cells and lamina X neurons induce a muscarinic-dependent short-term potentiation of commissural glutamatergic inputs in lumbar motoneurons.

open access: yesFrontiers in Neural Circuits, 2011
Acetylcholine and the activation of muscarinic receptors influence the activity of neural networks generating locomotor behaviour in the mammalian spinal cord.
