Alzheimers Dement

Centre for Addiction and Mental Health, Toronto, ON, Canada.
Background: Dysregulated GABA/somatostatin (SST) signaling has been implicated in psychiatric and neurodegenerative disorders. The inhibition of excitatory neurons by SST+ interneurons, particularly through α5-containing GABAA receptors (α5-GABAAR), plays a crucial role in mitigating cognitive functions. Previous research demonstrated that an α5-positive allosteric modulator (α5-PAM) mitigates working memory deficits and reverses neuronal atrophy in aged 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.

Université de Lille, Lille, Hauts-de-France, France.
Background: Tau proteins aggregate in a number of neurodegenerative disorders known as tauopathies. Various studies have highlighted the role of microtubule-binding domains in the intracellular aggregation of Tau protein.
Method: Using a library of synthetic VHHs humanized in collaboration with Hybrigenics, we have developed a number of anti-tau VHHs.

Department of Neurology and Neurological Sciences Stanford University School of Medicine, Stanford, CA, USA.
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).

Alzheimers Dement
December 2024
Chitkara College of Pharmacy, Chitkara University, Rajpura, Punjab, India.
Background: Various studies have evidenced the neuroprotective role of SIRT1 activator. However, whether SIRT1 activator, Piceatannol pharmacological treatment is protective in chronic unpredictable stress induced memory dysfunction remains unknown. Therefore, this study design included testing the hypothesis that Piceatannol administered in chronic unpredictable stress induced memory dysfunction mice shows protective effects, explores & probes underlying the activation of SIRT1 pathway.
