Comparing 2 hypotheses side-by-side
This hypothesis proposes that C1q protein forms stable complexes with alectinib through electrostatic interactions between C1q's globular head domains and alectinib's aminopyridine moiety. Rather than facilitating receptor-mediated transcytosis, the C1q-alectinib complex specifically targets claudin-5 and occludin proteins at blood-brain barrier tight junctions. The complement C1q component binds to exposed negatively charged residues on claudin-5's extracellular loops, particularly glutamate an
**Molecular Mechanism and Rationale** The blood-brain barrier (BBB) represents one of the most formidable obstacles in treating neurodegenerative diseases, with tight junctions formed by specialized proteins creating an impermeable seal between brain endothelial cells. The proposed piezoelectric nanochannel system targets two critical tight junction proteins: claudin-5 (CLDN5) and occludin (OCLN), which are fundamental components maintaining BBB integrity. CLDN5, a 23-kDa transmembrane protein,
