Alzheimers Dement
December 2024
NYU Grossman School of Medicine, New York, NY, USA; NYU, New York City, NY, USA.
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.

Alzheimers Dement
December 2024
Washington University School of Medicine, St. Louis, MO, USA.
Background: Alzheimer's disease neuropathology involves the deposition in brain of aggregates enriched with microtubule-binding-region (MTBR) of tau adopting an abnormal conformation between residues 306-378 in the core of aggregates. Anti-tau drugs targeting around this domain have the potential to interfere with the cell-to-cell propagation of pathological tau. Bepranemab is a humanized monoclonal Ig4 antibody binding to tau residues 235-250.

Alzheimers Dement
December 2024
Federal University of Technology, Akure, Ondo, Nigeria.
Background: In recent decades, epidemiological and experimental studies have looked into the role of pesticides, particularly the herbicide paraquat, in the development of Parkinson's disease. Horseradish tree (Moringa oleifera) is an ethnobotanical plant with lots of therapeutic potential, but there is a dearth of information on the bioactive properties of the seed alkaloid extracts.
Method: This study examined the modulatory effects of various concentrations of an alkaloid extract from the seeds of Horseradish Tree (Moringa oleifera) on the survival rate of flies exposed to paraquat, as well as certain biochemical and molecular markers related to Parkinson's disease in the heads of the flies.

Alzheimers Dement
December 2024
Ahmadu Bello University Zaria, Zaria, Kaduna, Nigeria.
Background: Studies suggest a potential link between stroke and Alzheimer's disease wherein stroke may serve as a trigger for the onset or acceleration of Alzheimer's pathogenesis as damage to the brain's blood vessels may lead to the accumulation of amyloid beta protein which is a hallmark of Alzheimer's disease. Recent research has shown that stroke treatment may hold the key to treating Alzheimer's disease. The anti-inflammatory potentials of Cholinergic signaling are a novel therapeutic target in memory decline associated with Alzheimer's.

Alzheimers Dement
December 2024
Shoolini University, Solan, Himachal Pradesh, India.
Background: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by progressive cognitive decline, neuroinflammation, and mitochondrial dysfunction. In Alzheimer's, abnormal Mitochondrial Permeability Transition Pore (mPTP) activity may contribute to mitochondrial dysfunction and neuronal damage. Withanolide A, a naturally occurring compound derived from Withania somnifera, have shown potential neuroprotective effects in various neurological disorders.
