Oligodendrocyte-specific promoter, miRNA specific to PLP1 gene, vector including said promoter and/or miRNA, and pharmaceutical composition including said vector
The purpose of the present invention is to provide a vector, a promoter and miRNA for the same, and a pharmaceutical composition including the vector, whereby expression of the PLP1 gene can be suppressed specifically in oligodendrocytes in order to treat PMD caused by an abnormality in the PLP1 gene. This oligodendrocyte-specific promoter includes a nucleic acid having at least 90% sequence identity with the base sequence represented by SEQ ID NO: 1. This miRNA specific to the PLP1 gene has a pair of base sequences comprising a predetermined antisense sequence and sense sequence.
