This invention relates to the field of therapeutic drugs and systems for
nervous system diseases, specifically to the application of Nrf2 in the preparation of therapeutic systems for treating
nervous system diseases caused by tRNA synthetase deficiency. Through research on tRNA synthetase-deficient mutants, we discovered that tRNA synthetase deficiency causes a reduction in the size of the mesencephalon in
zebrafish, resulting in symptoms of cerebellar
hypoplasia and
cerebral atrophy. In-depth research on the Perk signaling pathway involved in the above process revealed that the nfe2l2b
gene and the Nrf2
protein are
key factors regulating
neural development, and their downstream
target gene is p53. The inventors further applied the nfe2l2
gene to the preparation of therapeutic systems for treating
nervous system diseases and to related
drug screening, solving the technical problem of the lack of effective treatments for nervous
system diseases caused by tRNA synthetase deficiency in the prior art, and possessing ideal value for widespread application.
