Chronic Nicotine Selectively Enhances α4β2* Nicotinic Acetylcholine Receptors in the Nigrostriatal Dopamine Pathway [PDF]
These electrophysiological experiments, in slices and intact animals, study the effects of in vivo chronic exposure to nicotine on functional α4β2* nAChRs in the nigrostriatal dopaminergic (DA) pathway.

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Postsynaptic Complexin Mediates Constitutive Exocytosis of Nicotinic Acetylcholine Receptor
Beyond its established presynaptic role, complexin is identified as a postsynaptic regulator of neurotransmitter receptor trafficking. By promoting constitutive and activity‐dependent exocytosis of nicotinic acetylcholine receptors, complexin controls spontaneous synaptic signaling at the C.

Silent agonists for α7 nicotinic acetylcholine receptors
We discuss models for the activation and desensitization of α7 nicotinic acetylcholine receptors (nAChRs) and the effects of efficacious type II positive allosteric modulators (PAMs) that destabilize α7 desensitized states.

Distribution of α7 Nicotinic Acetylcholine Receptor Subunit mRNA in the Developing Mouse. [PDF]
Homomeric α7 nicotinic acetylcholine receptors (nAChRs) are abundantly expressed in the central and peripheral nervous system (CNS and PNS, respectively), and spinal cord.

Conditional expression in corticothalamic efferents reveals a developmental role for nicotinic acetylcholine receptors in modulation of passive avoidance behavior [PDF]
Prenatal nicotine exposure has been linked to attention deficit hyperactivity disorder and cognitive impairment, but the sites of action for these effects of nicotine are still under investigation. High-affinity nicotinic acetylcholine receptors (nAChRs)

An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Evolution of vertebrate nicotinic acetylcholine receptors
Background Many physiological processes are influenced by nicotinic acetylcholine receptors (nAChR), ranging from neuromuscular and parasympathetic signaling to modulation of the reward system and long-term memory.

The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Cholinergic modulation of dopamine overflow in the rat neostriatum: A fast cyclic voltammetric study in vitro [PDF]
Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon ...
