First described clinically in 1906, Alzheimer's disease (AD) is the most common neurodegenerative disease and form of dementia worldwide. Despite its prevalence, only five therapies are currently approved for AD, all dealing with the symptoms rather than the underlying causes of the disease. A multitude of experimental evidence has suggested that the once thought inconsequential process of neuroinflammation does, in fact, contribute to the AD pathogenesis. One such CNS cell type critical to this process are microglia. Plastic in nature with varied roles, microglia are emerging as key contributors to AD pathology. This review will focus on the role of microglia in the neuroinflammatory response in AD, highlighting recent studies implicating aberrant changes in microglial function in disease progression. Of critical note is that with these advances, a reconceptualization of the framework in which we view microglia is required.

Alzheimer's disease (AD) is associated with cognitive impairments which are linked to a deficit in cholinergic function. The objective of this study was to evaluate the ability of TeMac™ to prevent memory impairment in scopolamine-rats model of Alzheimer's disease and by in silico approaches to identify molecules in TeMac™ inhibiting acetylcholinesterase. The cholinergic cognitive dysfunction was induced by intraperitoneal injection of scopolamine (1 mg/kg daily) in male Wistar rats for seven consecutive days.

Neuroinflammation and mitochondrial dysfunction are early events in Alzheimer's disease (AD) and contribute to neurodegeneration and cognitive impairment. Evidence suggests that the inflammatory axis mediated by macrophage migration inhibitory factor (MIF) binding to its receptor, CD74, plays an important role in many central nervous system (CNS) disorders such as AD. Our group has developed DRhQ, a novel CD74 binding construct which competitively inhibits MIF binding, blocks macrophage activation and migration into the CNS, enhances anti-inflammatory microglia cell numbers and reduces pro-inflammatory gene expression.

Alzheimer's Disease (AD), a progressive and age-associated neurodegenerative disorder, is primarily characterized by amyloid-beta (Aβ) plaques and neurofibrillary tangles. Despite advances in targeting Aβ-mediated neuronal damage with anti-Aβ antibodies, these treatments provide only symptomatic relief and fail to address the multifactorial pathology of the disease. This necessitates the exploration of novel therapeutic approaches and a deeper understanding of molecular signaling mechanisms underlying AD.

Introduction: Transcranial pulse stimulation (TPS) is increasingly being investigated as a promising potential treatment for Alzheimer's disease (AD). Although the safety and preliminary clinical efficacy of TPS short pulses have been supported by neuropsychological scores in treated AD patients, its fundamental mechanisms are uncharted.
Methods: Herein, we used a multi-modal preclinical imaging platform combining real-time volumetric optoacoustic tomography, contrast-enhanced magnetic resonance imaging, and ex vivo immunofluorescence to comprehensively analyze structural and hemodynamic effects induced by TPS.
