This review discusses the current progress in clinical use of magnetic resonance-guided focused ultrasound (MRgFUS) and other platforms to transiently permeabilize blood-brain barrier (BBB) for drug delivery neurological disorders neuro-oncology. Safety trials humans have followed on from extensive pre-clinical studies, demonstrating a reassuring safety profile paving way numerous translational Alzheimer’s disease, Parkinson’s primary metastatic brain tumors. Future directions include improving devices, exploring alternative approaches such as nanodroplets, expanding application conditions.

Within an hour opening BBB, either AAV2 or AAV9 was delivered systemically via tail-vein In all marmosets, fluorescence-encoded neurons were observed at site perturbation, with showing sparse distribution transduced when compared to AAV9. The results are direct intracortical injections anterograde tracers into and similar (albeit sparser) long-range connectivity observed.

ABSTRACT Gene therapy for neurodegenerative diseases faces significant challenges due to the blood-brain barrier (BBB), which limits drug delivery central nervous system (CNS). While clinical trials Parkinson’s disease (PD) have progressed, administration of vectors expressing enzymatic or neurotrophic factor transgenes required extensive optimization method achieve potentially therapeutic levels transgene expression. Focused ultrasound (FUS) combined with microbubbles has emerged as a promising non-invasive strategy transiently open BBB targeted gene via viral nanocarriers including recombinant adeno-associated viruses (AAVs). However, key factors influencing FUS-mediated AAV delivery, dose distribution and efficacy, remain underexplored in non-human primates (NHPs). Here, we evaluated feasibility AAV9-CAG-GFP using two portable modalities: ultrasound-guided, spherically-focused FUS (USgFUS) novel low-frequency linear array configuration imaging called theranostic (ThUS). In mice, FUS-sonicated regions exhibited 25-fold increase AAV9 biodistribution compared systemic injection alone. Extending this approach NHPs, observed up 200-fold DNA treated brain regions, PD-relevant structures. assessing translational potential technique, ThUS-mediated AAV9-hSyn-hNTRN (human neurturin) toxin mouse model PD facilitated rescue 80% 75% degenerated dopaminergic neurons substantia nigra striatum, respectively. These findings demonstrate that technologies can non-invasively enhance both mice NHPs relative what be achieved intravenous (IV) same capsid With further development, these approaches may offer clinically viable, alternative diseases.

Introduction The blood-brain barrier (BBB) is a vascular endothelial membrane which restricts entry of toxins, cells and microorganisms into the brain. At same time, BBB supplies brain with nutrients, key substrates for DNA RNA synthesis, regulatory molecules, removes metabolic waste products from to blood. breakdown and/or dysfunction have been shown in neurogenerative disorders including Alzheimer's disease (AD). Current data suggests that these changes may initiate contribute neuronal, synaptic cognitive dysfunction, possibly other aspects neurodegenerative processes.
