Construct

摘要

The present invention provides a construct comprising (i) a nucleotide sequence which encodes tyrosine hydroxylase (TH), (ii) a nucleotide sequence which encodes GTP- cyclohydrolase I (CH1) and (iii) a nucleotide sequence which encodes Aromatic Amino Acid Dopa Decarboxylase (AADC) wherein the nucleotide sequence encoding TH is linked to the nucleotide sequence encoding CHI such that they encode a fusion protein TH-CH1. The invention also provides a viral vector comprising such a nucleotide sequence and its use in the treatment and/or prevention of Parkinson's disease.
