Different Classes of Antidepressants Inhibit the Rat α7 Nicotinic Acetylcholine Receptor by Interacting within the Ion Channel: A Functional and Structural Study

open access: yesMolecules, 2021
Several antidepressants inhibit nicotinic acetylcholine receptors (nAChRs) in a non-competitive and voltage-dependent fashion. Here, we asked whether antidepressants with a different structure and pharmacological profile modulate the rat α7 nAChR through

The neuroprotective effects of activated α7 nicotinic acetylcholine receptor against mutant copper–zinc superoxide dismutase 1-mediated toxicity

open access: yesScientific Reports, 2020
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the selective and progressive loss of motor neurons. Although many drugs have entered clinical trials, few have shown effectiveness in the treatment of ALS.

Activation of α7 Nicotinic Acetylcholine Receptor Upregulates HLA-DR and Macrophage Receptors: Potential Role in Adaptive Immunity and in Preventing Immunosuppression

open access: yesBiomolecules, 2020
Immune response during sepsis is characterized by hyper-inflammation followed by immunosuppression. The crucial role of macrophages is well-known for both septic stages, since they are involved in immune homeostasis and inflammation, their dysfunction ...

Nicotine elicits prolonged calcium signaling along ventral hippocampal axons. [PDF]

open access: yesPLoS ONE, 2013
Presynaptic nicotinic acetylcholine receptors (nAChRs) have long been implicated in the modulation of CNS circuits. We previously reported that brief exposure to low concentrations of nicotine induced sustained potentiation of glutamatergic transmission ...

Pharmacological and Mechanistic Interventions for Cognitive Impairment Associated With Schizophrenia: A Review of Registered Clinical Trials

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Background Schizophrenia is characterized by positive, negative, and cognitive symptoms. Current pharmacological treatments often fail to address cognitive deficits. In this review of clinical trials, we aim to identify studies that explore neurobiological (non‐psychological) strategies to address Cognitive Impairment Associated with ...

Alpha 7 nicotinic receptors attenuate neurite development through calcium activation of calpain at the growth cone.

open access: yesPLoS ONE, 2018
The α7 nicotinic acetylcholine receptor (nAChR) is a ligand-gated ion channel that plays an important role in cellular calcium signaling contributing to synaptic development and plasticity, and is a key drug target for the treatment of neurodegenerative ...

Cortical synaptic NMDA receptor deficits in α7 nicotinic acetylcholine receptor gene deletion models: Implications for neuropsychiatric diseases

open access: yesNeurobiology of Disease, 2014
Microdeletion of the human CHRNA7 gene (α7 nicotinic acetylcholine receptor, nAChR) as well as dysfunction in N-methyl-d-aspartate receptors (NMDARs) have been associated with cortical dysfunction in a broad spectrum of neurodevelopmental and ...

Varenicline for cannabis use disorder: A randomized controlled trial

open access: yesAddiction, EarlyView.
Abstract Background and aims Although cannabis use is widespread and prevalence of cannabis use disorder (CUD) is increasing, limited advancements have been made in CUD medication development. The objective of this study was to test the efficacy of varenicline with medical management for reducing cannabis use in treatment‐seeking individuals with CUD ...

Evaluation of preclinical antipsychotic models used to support first‐in‐human clinical trials

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 7, Page 1364-1389, April 2026.
Abstract Schizophrenia is regarded as a complex and heterogeneous psychiatric disorder, characterised by diverse symptoms and comorbidities, which complicate both clinical management and drug development. Current pharmacological treatment, primarily based on dopamine D2 receptor antagonism or partial agonism, which has not markedly progressed since the

Influence of Tobacco Smoke Exposure on the Protein Expression of α7 and α4 Nicotinic Acetylcholine Receptors in Squamous Cell Carcinoma Tumors of the Upper Aerodigestive Tract (Out of the Larynx)

open access: yesSubstance Abuse: Research and Treatment, 2018
Purpose: To assess protein expression of α7 and α4 nicotinic acetylcholine receptors (nAChR) subtypes in squamous cell carcinoma of the upper aerodigestive track (out of the larynx) according to tobacco smoke exposure, considering the general ...
