Open frontiers
All gaps →The debate proposed temporal SPI1 inhibition strategies but lacked data on when and how long SPI1 drives pathological versus beneficial microglial functions. Understanding these dynamics is essential for therapeutic timing.

How do ANGPT1 and ZBTB7C mechanistically regulate infarct size in ischemic stroke?The study identifies genetic associations between ANGPT1/ZBTB7C variants and infarct volume in both mice and humans, but the specific molecular mechanisms by which these genes influence ischemic injury remain unexplained. Understanding these pathways is critical for developing targeted stroke therapies. Gap type: unexplained_observation Source paper: Integrative Mouse and Human Studies Implicate ANGPT1 and ZBTB7C as Susceptibility Genes to Ischemic Injury. (None, None, PMID:26542693)
What is the relative contribution of ZBTB7C's effects on neuronal apoptosis versus collateralization?The abstract mentions ZBTB7C may modulate ischemic response via both neuronal apoptosis and dynamic collateralization, but doesn't clarify which mechanism predominates or how they interact. This distinction is crucial for understanding therapeutic targets. Gap type: unexplained_observation Source paper: Integrative Mouse and Human Studies Implicate ANGPT1 and ZBTB7C as Susceptibility Genes to Ischemic Injury. (None, None, PMID:26542693)
What determines when tPA's effects are plasmin-dependent versus plasmin-independent in the ischemic brain?The abstract describes tPA having both fibrinolytic (plasmin-dependent) and non-fibrinolytic effects, but doesn't explain what molecular or contextual factors determine which pathway predominates. Understanding this switch mechanism is critical for developing targeted stroke therapies that preserve beneficial effects while minimizing harmful ones. Gap type: unexplained_observation Source paper: Fibrinolytic and Non-fibrinolytic Roles of Tissue-type Plasminogen Activator in the Ischemic Brain. (2024, Neuroscience, PMID:37574107)
How do NMDAR and LRP-1 receptors differentially mediate tPA's contradictory effects on neuronal survival?The abstract mentions tPA has 'various effects on neuronal survival' mediated by NMDAR and LRP-1, but doesn't explain how the same receptors can produce both protective and detrimental outcomes. This mechanistic gap limits rational design of receptor-selective interventions for stroke treatment. Gap type: unexplained_observation Source paper: Fibrinolytic and Non-fibrinolytic Roles of Tissue-type Plasminogen Activator in the Ischemic Brain. (2024, Neuroscience, PMID:37574107)
What mechanisms coordinate tPA release from multiple cell types during cerebral ischemia?The abstract states that ischemia triggers rapid tPA release from endothelial cells, astrocytes, microglia, and neurons simultaneously, but doesn't address how this multi-cellular response is coordinated. Understanding this coordination is essential for predicting and modulating the overall tPA response in stroke. Gap type: unexplained_observation Source paper: Fibrinolytic and Non-fibrinolytic Roles of Tissue-type Plasminogen Activator in the Ischemic Brain. (2024, Neuroscience, PMID:37574107)
What molecular mechanisms explain why systemic AQP4 inhibition impairs glymphatic function while targeted inhibition preserves it?The abstract reveals that systemic TGN paradoxically exacerbates glymphatic dysfunction despite alleviating edema, while targeted delivery preserves glymphatic function. The mechanistic basis for this spatial selectivity of AQP4's dual roles remains unexplained, limiting rational therapeutic design. Gap type: unexplained_observation Source paper: Amelioration of Post-Stroke Edema and Microcirculatory Dysfunction via Targeted AQP4 Inhibition While Preserving the Glymphatic System. (2026, Advanced science (Weinheim, Baden-Wurttemberg, Germany), PMID:41387988)
How does AQP4 inhibition mechanistically reverse the no-reflow phenomenon in ischemic stroke?The abstract demonstrates that TGN mitigates no-reflow phenomenon in ischemic stroke, but the underlying mechanism linking AQP4 inhibition to microvascular reperfusion is not explained. Understanding this pathway could reveal new targets for post-stroke reperfusion therapy. Gap type: unexplained_observation Source paper: Amelioration of Post-Stroke Edema and Microcirculatory Dysfunction via Targeted AQP4 Inhibition While Preserving the Glymphatic System. (2026, Advanced science (Weinheim, Baden-Wurttemberg, Germany), PMID:41387988)
