Enteric glial cells (EGCs) are specialized glial cells of the enteric nervous system (ENS) that regulate intestinal function, support enteric neurons, and maintain the gut barrier. These cells are increasingly recognized for their role in neurodegenerative diseases, particularly Parkinson's disease.[1]
Enteric Glial Cells are the equivalent of astrocytes in the gut, forming a network throughout the intestinal wall. They are characterized by the expression of GFAP (glial fibrillary acidic protein), S100B (S100 calcium-binding protein), SOX10 (SRY-box transcription factor 10), PLP1 (proteolipid protein 1), and GDNF (glial cell line-derived neurotrophic factor).[2]
There are two main types of EGCs:
EGCs are essential for maintaining gut homeostasis, supporting enteric neurons, regulating intestinal barrier function, and modulating immune responses.[3]
In Parkinson's disease, alpha-synuclein pathology is found in enteric glial cells, suggesting they may be involved in disease initiation and spread.[4]
Enteric glia support enteric neurons:
EGCs maintain intestinal barrier integrity:
These cells regulate gut motility:
In PD, enteric glia show:
Enteric glial pathology contributes to:
The study of Enteric Glial Cells In Neurodegeneration has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
