Background: The initiation of amyloid plaque deposition signifies a crucial stage in Alzheimer's disease (AD) progression, which often coincides with the disruption of neural circuits and cognitive decline. While the role of excitatory-inhibitory balance is increasingly recognized in AD pathophysiology, targeted therapies to modulate this balance remain underexplored. This study investigates the effect of perampanel, a selective non-competitive AMPA receptor antagonist, in modulating neurophysiological changes in hAPP-J20 transgenic Alzheimer's mice.

Background: Astrocytes, a major glial cell in the central nervous system (CNS), can become reactive in response to inflammation or injury, and release toxic factors that kill specific subtypes of neurons. Over the past several decades, many groups report that reactive astrocytes are present in the brains of patients with Alzheimer's disease, as well as several other neurodegenerative diseases. In addition, reactive astrocyte sub-types most associated with these diseases are now reported to be present during CNS cancers of several types.

Anti-Aβ immunotherapies are controversial, in part because of high rates of serious side effects including edema, microhemorrhages, and siderosis, highlighting the importance of the development of alternative Aβ clearance strategy. Here, we introduce a bioinspired nanoparticle named MG-PE3 crossing the human blood-brain barrier (BBB) and clearing Aβ with no adverse effect.

SORL1 encodes the retromer-associated receptor SORLA that plays an essential role in recycling of AD-associated cargos such as the amyloid precursor protein and the glutamatergic AMPA receptor. Importantly, loss of function pathogenic SORL1 variants are associated with AD.

Dementia patients often received one clinical diagnosis, yet most of these cases present multiple underlying pathologies. Bringing the transition from clinical-based to biological-based diagnosis holds promise with the diagnostic criteria proposed by the Alzheimer's Association (AA) Revised Criteria for Diagnosis and Staging of Alzheimer's Disease and the Neuronal Synuclein Disease Integrated Staging System (NSD-ISS). This session aims to explore the practical implications of the AA revised criteria for diagnosing and designing clinical trials in Lewy body disease (LBD).
