The Role of Oligodendrocyte Lineage Cells in the Pathogenesis of Alzheimer's Disease.

Alzheimer's disease (AD) is a central nervous system degenerative disease with a stealthy onset and a progressive course characterized by memory loss, cognitive dysfunction, and abnormal psychological and behavioral symptoms. However, the pathogenesis of AD remains elusive. An increasing number of studies have shown that oligodendrocyte progenitor cells (OPCs) and oligodendroglial lineage cells (OLGs), especially OPCs and mature oligodendrocytes (OLGs), which are derived from OPCs, play important roles in the pathogenesis of AD.

Huntington's disease (HD) is a progressive neurodegenerative disease resulting from a mutation in the huntingtin (HTT) gene and characterized by progressive motor dysfunction, cognitive decline, and psychiatric disturbances. Currently, no disease-modifying treatments are available. Recent research has developed therapeutic agents that may have the potential to directly target the disease pathology, such as gene silencing or clearing the mutant protein.

Eli Lilly and Company, Indianapolis, IN, USA.
Background: Anti-amyloid-β (Aβ) immunotherapy trials have shown amyloid-related imaging abnormalities (ARIA) as the most common and serious adverse events linked to pathological changes in cerebral vasculature. Nevertheless, the mechanisms underlying how amyloid immunotherapy triggers vascular damage, increases vascular permeability, and results in microhemorrhages remains unclear. Notably, activation of perivascular macrophages and infiltration of peripheral immune cells have been implicated in regulating cerebrovascular damage.

Alzheimers Dement
December 2024
VIB-UGent Center for Inflammation Research, Ghent, Belgium.
Background: The brain is shielded from the peripheral circulation by central nervous system (CNS) barriers, comprising the well-known blood-brain barrier (BBB) and the less recognized blood-cerebrospinal fluid (CSF) barrier located within the brain ventricles. The gut microbiota represents a diverse and dynamic population of microorganisms that can influence the health of the host, including the development of neurological disorders like Alzheimer's disease (AD). However, the intricate mechanisms governing the interplay between the gut and brain remain elusive, and the means by which gut-derived signals traverse the CNS barriers remain unclear.

Alzheimers Dement
December 2024
Gladstone Institutes, UCSF, San Francisco, CA, USA.
Background: Cerebrovascular alterations and innate immune activation are key features of Alzheimer's disease (AD). However, the mechanisms that link blood-brain barrier disruption to neurodegeneration are poorly understood and well-defined druggable targets at the neurovascular interface are limited.
Method: By developing a multiomic and genetic loss-of-function pipeline, we reported the transcriptomic and global phosphoproteomic landscape of blood-induced microglia activation and the causal role for fibrin in induction of neurodegenerative genes and oxidative stress pathways in innate immune cells.
