Comparing 2 hypotheses side-by-side
This hypothesis proposes that covalent conjugation of alectinib to transferrin (Tf) creates a targeted drug delivery system that exploits the high expression of transferrin receptor 1 (TfR1) on brain capillary endothelial cells to enhance central nervous system penetration. Unlike passive diffusion or efflux pump inhibition strategies, this approach leverages the natural iron transport machinery of the blood-brain barrier. The transferrin-alectinib conjugate would bind to TfR1 with high affinity
**Mechanistic Foundation** Specialized pro-resolving mediators (SPMs) - including resolvins, protectins, and maresins - are endogenous lipid mediators that actively terminate neuroinflammation and promote tissue repair. Unlike anti-inflammatory drugs that merely block inflammatory pathways, SPMs actively stimulate resolution programs: clearance of apoptotic debris, restoration of blood-brain barrier integrity, and regeneration of damaged neural tissue. In Alzheimer's disease, SPM biosynthesis i
