JAK2 and intracerebral hemorrhage: This schematic shows Vinorine inhibits the activation of the CXCR2‐JAK–STAT pathway axis mediated by microglia after intracerebral hemorrhage by targeting the JAK2 protein, thereby reducing the release of metalloproteinases, protecting the blood–brain barrier function, and reducing neuronal apoptosis, indicating that it has a certain effect in alleviating secondary brain damage after intracerebral hemorrhage.
