Enteric Neurons In Alzheimer'S Disease is a cell type relevant to neurodegenerative disease research. This page covers its role in brain function, involvement in disease processes, and significance for therapeutic strategies.
Enteric neurons in Alzheimer's disease refer to the neurons of the enteric nervous system (ENS) that are affected by Alzheimer's disease pathology. The ENS contains millions of neurons controlling gastrointestinal function. Recent research suggests that alpha-synuclein pathology may propagate from the gut to the brain via the vagus nerve, and enteric neurons show early pathological changes in AD.
The enteric nervous system (ENS), often called the "second brain," is increasingly recognized as affected in Alzheimer's disease. Gastrointestinal dysfunction is common in AD and may precede cognitive symptoms.
