α7 and β2 Nicotinic Acetylcholine Receptor Subunits Form Heteromeric Receptor Complexes that Are Expressed in the Human Cortex and Display Distinct Pharmacological Properties.

PLoS ONE, 2015
The existence of α7β2 nicotinic acetylcholine receptors (nAChRs) has recently been demonstrated in both the rodent and human brain. Since α7-containing nAChRs are promising drug targets for schizophrenia and Alzheimer's disease, it is critical to ...

The Effect of the Anticonvulsant Topiramate on Acetylcholine‐Induced Calcium Signals is Linked to Sirt‐1 Activity

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
This work provides a potential new link between the anticonvulsive Topiramate, the deacetylase Sirt‐1 and the cholinergic signalling, suggesting that Topiramate may modulate cholinergic pathways in a Sirt‐1 depended manner. ABSTRACT Although some forms of epilepsy directly result from mutations in nicotinic acetylcholine receptors, none of the ...

Deficiency of α7 Nicotinic Acetylcholine Receptor Attenuates Bleomycin-Induced Lung Fibrosis in Mice

Molecular Medicine, 2017
α7 nicotinic acetylcholine receptor (α7 nAChR, coded by Chrna7) is indispensable in dampening proinflammatory responses. However, whether α7 nAChR plays a role in regulating bleomycin (BLM)-induced lung fibrosis is less investigated.

Suppression of neuroinflammation by an allosteric agonist and positive allosteric modulator of the α7 nicotinic acetylcholine receptor GAT107

Journal of Neuroinflammation, 2021
Background The α7 nicotinic acetylcholine receptor (α7 nAChR) negatively regulates the synthesis and release of pro-inflammatory cytokines by immune cells.

Nicotinic receptor components of amyloid beta 42 proteome regulation in human neural cells.

PLoS ONE, 2022
Alzheimer's disease (AD) is associated with chronic neurodegeneration often accompanied by elevated levels of the neurotoxic peptide amyloid-beta 1-42 (Aβ42) in the brain.

Review: “The Disappointment Dilemma: Short‐ and Long‐Term Learning From Negative Outcomes”

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
The habenula routes negative‐outcome signals to VTA, RMTg, and IPN to shape aversive learning and motivation. The lateral habenula encodes acute negative prediction errors to rapidly adapt behavior to threat, fear, and avoidance. The medial habenula integrates repeated stress, drug, and aversive experiences into long‐term negative mood and expectations.

Towards Mechanism‐Informed Treatments for Mental Health

Journal of Neurochemistry, Volume 170, Issue 5, May 2026.
Neuropsychiatric disorders impose a major global health burden, and current treatments, which historically mostly targeted dopamine and serotonin dysfunctions, often provide only partial, symptomatic relief. This review highlights emerging evidence that additional neuromodulator systems, including acetylcholine, norepinephrine, and endocannabinoids ...

Novel insights into extracellular vesicles: An update on biomolecules, immunomodulation and clinical strategies in skin melanoma

Clinical and Translational Medicine, Volume 16, Issue 4, April 2026.
Extracellular vesicles mediate melanoma progression by transferring biomolecules (proteins, nucleic acids) that reshape the tumour microenvironment, promote immune evasion and drive metastasis. They also serve as diagnostic biomarkers and engineered therapeutic carriers for targeted therapy.

Nicotine Suppresses Human Memory Th Cell Subsets With Preferential Effects on Central Memory Th Cells in an α7 Nicotinic Acetylcholine Receptor‐Dependent Manner

European Journal of Immunology, Volume 56, Issue 4, April 2026.
Human memory Th cells were separated into Tcm (CD45RO+ CD62L+) and Tem (CD45RO+ CD62L−). Nicotine preferentially suppressed Th1‐, Th2‐, Th17‐, and Tfh‐associated programs in Tcm via an α7nAChR‐dependent mechanism, with minimal effect in Tem. ABSTRACT Memory T helper (Th) cells sustain protective recall responses but can also drive chronic inflammation,
