Enteroendocrine Neurons In Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Enteroendocrine Neurons are specialized sensory cells in the gastrointestinal tract that detect nutrients and chemical signals, connecting the gut to the brain through neural and hormonal pathways. These cells are increasingly recognized for their role in gut-brain axis communication and their involvement in neurodegenerative disease pathogenesis. [@sampson2016]
Overview
Enteroendocrine cells (EECs) constitute the largest endocrine organ in the body and include multiple cell types that: [@cryan2019]
Sense luminal contents
Release signaling molecules
Communicate with enteric nervous system
Modulate brain function via neural and hormonal pathways
Serotonin (5-HT): Enterochromaffin cells produce 95% of body serotonin
GLP-1: Glucagon-like peptide-1, affects appetite and cognition
PYY: Peptide YY, satiety signaling
CCK: Cholecystokinin, gut-brain peptide
GABA: Inhibitory neurotransmitter
Dopamine: Reward and movement
