Stimulation of GABA brain receptors by calcium bis acetyl-homotaurine (a new GABAergic agent) or of noradrenergic brain receptors by metapramine reduces the voluntary intake of ethanol by rats. Bicuculline antagonizes the effects of both drugs. It is suggested that both GABA and noradrenaline are implicated in ethanol intake, and that there is a common final pathway of the two systems to modulate ethanol intake.

The Receptor for Advanced Glycation End-products in the Mouse Anterior Cingulate Cortex is Involved in Neuron‒Astrocyte Coupling in Chronic Inflammatory Pain and Anxiety Comorbidity.

Previous studies have shown that astrocyte activation in the anterior cingulate cortex (ACC), accompanied by upregulation of the astrocyte marker S100 calcium binding protein B (S100B), contributes to comorbid anxiety in chronic inflammatory pain (CIP), but the exact downstream mechanism is still being explored. The receptor for advanced glycation end-products (RAGE) plays an important role in chronic pain and psychosis by recognizing ligands, including S100B. Therefore, we speculate that RAGE may be involved in astrocyte regulation of the comorbidity between CIP and anxiety by recognizing S100B.

Akuammicine (AKC), an indole alkaloid, is a kappa opioid receptor (KOR) full agonist with a moderate affinity. 10-Iodo-akuammicine (I-AKC) and 10-Bromo-akuammicine (Br-AKC) showed higher affinities for the KOR with K values of 2.4 and 5.

The blood-brain barrier is a physiological barrier that can prevent both small and complex drugs from reaching the brain to exert a pharmacological effect. For treatment of neurological diseases, drug concentrations at the target site are a fundamental parameter for therapeutic effect; thus, the blood-brain barrier is a major obstacle to overcome. Novel strategies have been developed to circumvent the blood-brain barrier, including CSF delivery, intracranial delivery, ultrasound-based methods, membrane transporters, receptor-mediated transcytosis, and nanotherapeutics.

Distinguishing tumor maintenance genes from initiation, progression, and passenger genes is critical for developing effective therapies. We employed a functional genomic approach using the Lazy Piggy transposon to identify tumor maintenance genes in vivo and applied this to sonic hedgehog (SHH) medulloblastoma (MB). Combining Lazy Piggy screening in mice and transcriptomic profiling of human MB, we identified the voltage-gated potassium channel KCNB2 as a candidate maintenance driver.

Cigarette smoke (CS), an indoor environmental pollution, is an environmental risk factor for diverse neurological disorders. However, the neurotoxicological effects and mechanisms of CS on Alzheimer's disease (AD) progression remain unclear. We found that CS accelerated the progression of AD, including increasing β-amyloid (Aβ) plaque deposition and exacerbating cognitive decline.
