Adolescent Exposure to Nicotine and Ethanol Attenuates Adult Nicotine Reward Sensitivity in Rats

Neuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
We investigated how chronic exposure to nicotine, ethanol, or their combination during adolescence influences adult conditioned place preference (CPP) for nicotine. No significant CPP was observed in any of the drug‐exposed groups, suggesting adolescent exposure to addictive substances does not uniformly increase vulnerability to nicotine reward ...

The Use of Statins in Parkinson's and Alzheimer's Disease: A 2021–2025 State‐of‐the‐Art Review of Clinical and Preclinical Evidence

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Statins, widely prescribed for cardiovascular prevention, have emerged as potential disease‐modifying agents in neurodegenerative disorders due to their pleiotropic effects on cholesterol metabolism, neuroinflammation, oxidative stress, and protein aggregation.

α7 Nicotinic acetylcholine receptor-specific antibody induces inflammation and amyloid β42 accumulation in the mouse brain to impair memory.

PLoS ONE, 2015
Nicotinic acetylcholine receptors (nAChRs) expressed in the brain are involved in regulating cognitive functions, as well as inflammatory reactions. Their density is decreased upon Alzheimer disease accompanied by accumulation of β-amyloid (Aβ42), memory

Restoring Septohippocampal Cholinergic Signaling Rescues Surgery‐Induced Neurogenesis and Memory Deficits in Aged Mice

Aging Cell, Volume 25, Issue 6, June 2026.
Surgery‐induced MS/vDB → DG cholinergic decline impairs hippocampal neurogenesis and memory in aged mice; galantamine‐mediated cholinergic potentiation or sustained chemogenetic activation rescues these deficits, highlighting therapeutic potential for POCD.

Structural basis for allosteric agonism of human α7 nicotinic acetylcholine receptors

Cell Discovery
The α7 nicotinic acetylcholine receptor (nAChR), a pentameric ligand-gated ion channel, plays important roles in cognition, neuroprotection, and anti-inflammation.

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

Food Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...

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

Acta Psychiatrica Scandinavica, Volume 153, Issue 5, Page 402-431, May 2026.
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 ...

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 ...

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 ...
