Description
The study identifies reduced STAT3 expression in splenic NK cells after brain ischemia, but the communication pathway between the ischemic brain and peripheral immune organs remains unknown. This brain-immune crosstalk mechanism is essential for understanding stroke-induced systemic immunosuppression.
Gap type: unexplained_observation Source paper: Activation of JAK/STAT3 restores NK-cell function and improves immune defense after brain ischemia. (None, None, PMID:29401578)
