• Genetics

Background:

• Gene therapy holds significant promise for treating neurodegenerative diseases such as Parkinson's, Huntington's, and Alzheimer's.
• Therapeutic success hinges on understanding disease pathogenesis and achieving precise gene expression.
• Accurate vector delivery, avoiding off-target spread, remains a critical challenge.

Purpose of the Study:

• To highlight the transformative potential of gene therapy in neurodegenerative disorders.
• To emphasize the importance of precise gene delivery for therapeutic efficacy.
• To introduce interventional MRI-guided convection-enhanced delivery (iMRI-CED) as a key technological advancement.

Main Methods:

• Review of current gene therapy strategies for neurodegenerative diseases.
• Discussion of challenges in achieving targeted and efficient gene transduction.
• Introduction of interventional MRI-guided convection-enhanced delivery (iMRI-CED) as a neurosurgical technique.

Main Results:

• Gene therapy can address neurodegenerative diseases through mechanism correction, neuroprotection, neurorestoration, and symptom control.
• Precise spatial and temporal control of gene expression is crucial for therapeutic efficacy.
• iMRI-CED enables real-time verification of vector delivery, establishing it as a gold standard.

Conclusions:

• The advent of iMRI-CED represents a new technological era in gene therapy for neurodegenerative disorders.
• This advanced delivery method facilitates accurate vector placement and minimizes off-target effects.
• iMRI-CED is poised to accelerate the clinical translation of promising gene therapies for conditions like Parkinson's, Huntington's, and Alzheimer's diseases.
