Desenvolvimento de um modelo de rato baseada alfa-sinucleína para a doença de Parkinson por meio de injecção estereotáxica de um vector viral recombinante adeno-associado

Overview

This manuscript describes a method for developing a viral vector-based animal model for Parkinson's disease through stereotactic injection in the central nervous system. This technique allows for targeted gene expression in specific brain regions, facilitating pre-clinical drug testing and the study of neurodegenerative disorders.
