Angiogenic Cell Precursors and Neural Cell Precursors in Service to the Brain-Computer Interface

Area of Science:

• Neuroscience
• Biomaterials Science
• Regenerative Medicine

Background:

• Brain-computer interfaces (BCIs) utilize advanced electrode technology for neural prosthetics, enabling paralyzed individuals to control devices and blind individuals to read.
• Implanted electrodes trigger foreign body reactions, including inflammation, scarring, and apoptosis, leading to signal degradation and device failure within 6-12 months.

Purpose of the Study:

• To propose a novel biomolecular strategy to enhance the longevity and efficacy of BCIs.
• To mitigate the adverse biological responses associated with chronic neural implants.

Main Methods:

• Administration of angiogenic cell precursors (ACPs) and nerve cell precursors (NCPs) intrathecally.
• Leveraging cell-based therapy to modulate the neuro-inflammatory environment and promote neural plasticity.

Main Results:

• The proposed combination therapy is anticipated to sustain and promote learning across the BCI.
• Potential for downstream activation of neurotrophic factors to suppress inflammation, reduce apoptosis, and enhance homeostasis.
• Expected promotion of angiogenesis, differentiation, synaptogenesis, neuritogenesis, and learning-associated plasticity.

Conclusions:

• Intrathecal administration of ACPs and NCPs offers a promising strategy to overcome the biological limitations of current BCIs.
• This approach may significantly extend the functional lifespan of neural implants and improve patient outcomes.
• The therapy holds potential for broad applications in neural repair and neurodegenerative disease treatment.
