Nestin is a class VI intermediate filament protein encoded by the NES gene. Originally discovered as a neural stem cell marker, nestin is expressed in proliferating neural progenitor cells during development and in certain populations of adult stem cells. While primarily a cytoskeletal protein, nestin has been implicated in various neurological conditions including Alzheimer's disease, Parkinson's disease, brain injury, and brain tumors [1].

Understanding nestin biology supports:
Nestin is a class VI intermediate filament protein that serves as a marker for neural stem and progenitor cells. While primarily a cytoskeletal protein, nestin participates in cell signaling, structural organization, and regenerative responses. In neurodegenerative diseases, nestin expression reflects attempted neural repair and may interact with pathological processes. Nestin-positive cells represent potential therapeutic targets for regenerative approaches in Alzheimer's disease, Parkinson's disease, and brain injury.
