When lactate speaks: Rewiring astrocyte-neuron metabolism in Alzheimer's disease

3 months 1 week ago
Metabolic dysfunction is a defining but poorly understood feature of Alzheimer's disease. Du et al. show that a brain-penetrant GLP-1 receptor agonist rewires astrocyte-neuron metabolic coupling through lactate-driven histone lactylation, linking astrocytic glycolysis to neuronal lipid homeostasis and positioning metabolite signaling as a therapeutic axis in neurodegeneration.

How do energy metabolism disorders and neuroinflammation collectively contribute to the pathogenesis of Alzheimer's disease?

3 months 1 week ago
Alzheimer's disease (AD), as the leading cause of dementia, poses an increasingly severe socioeconomic burden in the context of global ageing. Traditionally defined by amyloid-β and tau pathology, it's increasingly recognized as a systems disorder in which impaired glucose metabolism, mitochondrial dysfunction, and neuroinflammation interact across neural cell types and disease stages. However, the interaction among these three mechanisms, their role in promoting the classical pathology of AD,...

An updated patent review of mGlu5 negative allosteric modulators (2018 - present)

3 months 1 week ago
Metabotropic glutamate receptor subtype 5 (mGlu5) is an important regulator of excitatory neurotransmission and remains a therapeutic target for neuropsychiatric and neurological disorders, including substance use disorders, depression, Fragile X syndrome, Parkinson's disease-related dyskinesia, and other movement disorders. However, the clinical development of mGlu5 negative allosteric modulators (NAMs) has been limited by translational challenges, inconsistent efficacy, and safety concerns,...
