Alzheimers Dement
December 2024
Columbia University Irving Medical Center, New York, NY, USA.
Background: Genetic studies indicate a causal role for microglia, the innate immune cells of the central nervous system (CNS), in Alzheimer's disease (AD). Despite the progress made in identifying genetic risk factors, such as CD33, and underlying molecular changes, there are currently limited treatment options for AD. Based on the immune-inhibitory function of CD33, we hypothesize that inhibition of CD33 activation may reverse microglial suppression and restore their ability to resolve inflammatory processes and mitigate pathogenic amyloid plaques, which may be neuroprotective.

Alzheimers Dement
December 2024
Department of Bioengineering, University of California, Los Angeles, CA, USA, Los Angeles, CA, USA.
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.

Alzheimers Dement
December 2024
School of Medical & Allied Sciences, K.R. Mangalam University, Gurugram, Haryana, India.
Background: Parkinson's disease is an hypokinetic disorder characterized by selective loss of dopaminergic in substantia nigra pars compacta (SNPc) region of mid-brain. Dopaminergic degeneration of neurons is considered to be due to oxidative stress, neuroinflammation, neurons mitochondrial dysfunction and glutamate excitotoxicity etc. Filgrastim has been reported to produce anti-oxidant, anti-inflammatory and neuromodulatory actions in previous studies.

Alzheimers Dement
December 2024
University of Southern California, Los Angeles, CA, USA.
Background: Blood pressure (BP) management is an accessible therapeutic target for dementia prevention. BP variability (BPV) is a newer aspect of BP control recently associated with cognitive decline, dementia and Alzheimer's disease (AD), independent of traditionally targeted mean BP levels. Most of this work has relied on largely non-Hispanic White study samples in observational cohorts.
View Article and Find Full Text PDFBackground: Alzheimer's disease is the most dreaded multifactorial neurological illness for which there is currently no known treatment. Although the exact cause of AD is still unknown, several factors related to lifestyle, genetics, and environment are known to have a significant role in the disease's development. Alzheimer's disease is characterized by neuronal loss, neurofibrillary tangles, and senile plaques.
