Alpha- synuclein immunoreactivity in the enteric nervous system of human small intestine
Alpha-synuclein (α-syn) is a 140 amino acid protein, belonging to the synuclein family, expressed in mammalian neurons. Structural alterations of α-syn as well as its overexpression have been related to the onset and the progression of several human neurodegenerative diseases, as Parkinson’s diseases (PD). Indeed, α-syn aggregates are the main component of the Lewy bodies (Lbs), considered as pathological hallmarks of neurodegenerative diseases [1-2], known as synucleinopathies.
