Transgenic (tg) mouse models overexpressing human α-syn under different oligodendroglia-specific promoters, such as proteolipid protein (PLP) [31], myelin basic protein (MBP) [51], and 2′,3′-cyclic nucleotide 3′-phosphodiesterase (CNP) [67], have been developed to study MSA. Here, CNP is linked to multiple system atrophy.
