JAK1 and stroke disorder: Mechanistically, ADSC-CM robustly activated JAK1 and STAT3 phosphorylation in both models, an effect effectively inhibited by GLPG0634.<h4>Discussion</h4>The neuroprotective effects of ADSC-CM are mechanistically linked to the activation of the JAK1/STAT3 pathway, which mitigates ischemic damage by promoting neuronal salvage, neurovascular regeneration, synaptic plasticity, and metabolic recovery, thereby enhancing neurological functional recovery after stroke.
