#	Title	Status	Priority	Domain	Created
1	Does empagliflozin's neuroprotective effect require SGLT2 presence in brain end… The mechanism assumes SGLT2-mediated effects, but brain endothelial SGLT2 expression is controversial and the study doesn't confirm target engagement. This gap … gap-pubmed-20260410-182947-b1819326	open	0.820	neurovascular biology	2026-04-10	Open →
2	What is the temporal sequence of blood-spinal cord barrier breakdown relative t… While barrier dysfunction was proposed as a convergence mechanism, the debate did not resolve whether it's a primary driver or secondary consequence of myelopat… gap-debate-20260410-105837-3bce07b6	open	0.800	neurovascular biology	2026-04-10	Open →
3	What are the specific molecular mechanisms by which circadian clocks regulate B… The abstract states that circadian clocks temporally regulate BBB permeability but does not explain the mechanistic basis for this regulation. Understanding the… gap-pubmed-20260411-083053-72a71b77	open	0.800	neurovascular biology	2026-04-11	Open →
4	How do astrocytes coordinate their dual roles in neurovascular coupling and syn… The abstract highlights astrocyte functions in both cerebral blood flow regulation and tripartite synapse maintenance, but the mechanistic integration of these … gap-pubmed-20260410-171911-a02eaba2	open	0.780	neurovascular biology	2026-04-10	Open →
5	How does FOXF2 mechanistically control chromatin accessibility at pro-angiogeni… While the study demonstrates FOXF2 maintains chromatin accessibility at pro-angiogenic sites, the specific chromatin remodeling mechanisms and co-factors involv… gap-pubmed-20260410-180520-7e0c3a64	open	0.560	neurovascular biology	2026-04-10	Open →
