Open frontiers
All gaps →SPM enhancement shows high therapeutic potential but faces critical delivery challenges that previous pharmaceutical efforts failed to solve. The debate identified this as a major feasibility barrier but provided no viable solutions for CNS targeting. Source: Debate session sess_sda-2026-04-01-gap-009 (Analysis: sda-2026-04-01-gap-009)
Can lipid nanoparticles achieve true astrocyte-selective delivery in the CNS?Multiple hypotheses relied on cell-type specific targeting, but the debate revealed uncertainty about whether current delivery technologies can achieve this selectivity. The feasibility of selective targeting determines whether these therapeutic approaches are viable.

What CNS penetration strategies can achieve therapeutic concentrations of proteostasis enhancers?The domain expert noted poor CNS penetration of existing autophagy enhancers like rapamycin, but alternative delivery methods weren't explored. This pharmacokinetic barrier represents a major obstacle to translating proteostasis-based therapies. Source: Debate session sess_SDA-2026-04-01-gap-012 (Analysis: SDA-2026-04-01-gap-012)
Can nanobodies achieve blood-brain barrier penetration while maintaining tau-binding specificity and membrane activity?The domain expert flagged BBB penetration as a major limitation for CNS nanobodies, but the debate didn't resolve whether membrane-active modifications compromise BBB transport or tau binding. This represents a critical feasibility bottleneck.

Can engineered protein scaffolds cross the blood-brain barrier without disrupting endogenous networks?Multiple experts highlighted delivery challenges and potential toxicity from artificial scaffolds sequestering normal proteins. The feasibility of CNS delivery while maintaining selectivity for disease-affected interactions remains experimentally unresolved.

What specific mechanisms enable EVs to cross the blood-brain barrier while other therapeutics cannot?The abstract states EVs have 'intrinsic ability to cross the BBB' but doesn't explain the underlying mechanisms. Understanding these mechanisms is crucial for optimizing EV-based therapeutics and potentially engineering other BBB-crossing delivery systems. Gap type: unexplained_observation Source paper: Therapeutic potential of extracellular vesicles in neurodegenerative disorders. (2023, Handbook of clinical neurology, PMID:36803815)
What are the key challenges limiting EVs as effective drug delivery vehicles for neurodegeneration?The abstract mentions that challenges exist for using EVs as delivery vehicles but doesn't specify what these limitations are. Identifying these barriers is essential for advancing EV-based therapeutics from research to clinical application. Gap type: open_question Source paper: Extracellular vesicles: biological mechanisms and emerging therapeutic opportunities in neurodegenerative diseases. (2024, Translational neurodegeneration, PMID:39643909)
How does intranasal delivery achieve preferential targeting to peri-infarct regions versus healthy brain tissue?The study shows increased circSCMH1 distribution in peri-infarct regions via intranasal delivery, but the mechanism for this selective targeting is unexplained. This knowledge gap limits optimization of delivery strategies and understanding of nose-to-brain transport in stroke conditions. Gap type: unexplained_observation Source paper: Nose-to-Brain Delivery of Circular RNA SCMH1-Loaded Lipid Nanoparticles for Ischemic Stroke Therapy. (2025, Advanced materials (Deerfield Beach, Fla.), PMID:40143778)
