## **Molecular Mechanism and Rationale**
The concept of ocular immune privilege extension leverages the unique immunoregulatory environment of the eye to establish systemic neuroprotection through engineered immune-regulatory cell therapy targeting FOXP3 and TGFB1 pathways. The eye maintains immune privilege through multiple molecular mechanisms, including the blood-retinal barrier, expression of immunosuppressive factors, and specialized antigen-presenting cell populations. Central to this pri
# LRP1-Dependent Tau Uptake Disruption in Tauopathic Neurodegeneration
## Background and Rationale
The progressive spreading of hyperphosphorylated tau pathology throughout the brain represents a hallmark of Alzheimer's disease and related tauopathies, including progressive supranuclear palsy, corticobasal degeneration, and frontotemporal lobar degeneration with tau inclusions. Central to this spreading mechanism is the intercellular transfer of pathological tau species, wherein diseased neuro
