1How does Cav1/caveolae mechanistically regulate mTORC1 protein trafficking and…
The study identifies that Cav1/caveolae increases intracellular trafficking and complex formation of mTORC1 signaling proteins in CCM3-depleted EPCs, but the pr…

3How does AQP4 inhibition mechanistically reverse the no-reflow phenomenon in is…
The abstract demonstrates that TGN mitigates no-reflow phenomenon in ischemic stroke, but the underlying mechanism linking AQP4 inhibition to microvascular repe…

4Why does endothelial YAP/TAZ loss reduce stroke lesions when YAP/TAZ typically…
The finding that YAP/TAZ depletion is neuroprotective contradicts established roles of these proteins in promoting regeneration and tissue repair. This unexpect…

6What determines when tPA's effects are plasmin-dependent versus plasmin-indepen…
The abstract describes tPA having both fibrinolytic (plasmin-dependent) and non-fibrinolytic effects, but doesn't explain what molecular or contextual factors d…
