Renovating Neural Networks With Viral-Mediated Gene Transfer From A Tissue Contacting Matrix Mimic

Abstract

Neurodegenerative diseases such as Huntington's Disease (HD) have a significant impact on healthcare accessibility and costs. A fatal genetic condition, characterized by the progressive loss of striatal neurons, HD is hindered by the lack of endogenous repair in the adult brain. Recent efforts toward protecting neural circuits through neurotrophic support using brain-derived neurotrophic factor (BDNF) have been suboptimal due to the protein's short half-life and limited diffusion. Addressing this, adeno-associated viral vectors (AAV) can be employed as a delivery tool to spatially transduce cells, enabling the localised production of BDNF with consequential neuron protection and/or plasticit..
