Description
The abstract highlights TGFβ signaling as particularly important in epilepsy, stroke, and Parkinson’s disease but doesn’t explain the specific mechanisms by which it connects BBB compromise to pathogenesis. This mechanistic gap limits therapeutic targeting of this pathway.
Gap type: unexplained_observation Source paper: Blood-brain barrier dysfunction-induced inflammatory signaling in brain pathology and epileptogenesis. (None, None, PMID:23134494)
