Monocytes Are Major Players in the Prognosis and Risk of Infection After Acute Stroke

Abstract

In human stroke, poor outcome is associated to innate responses mediated by Toll-like receptor-4 in monocytes. SAI may result from the immunosuppressive and antiinflammatory effects of corticoids, catecholamines, IL-10, and deactivated monocytes. Early treated SAI does not contribute significantly to additional brain damage. These findings encourage the exploration of strategies aimed to inhibit Toll-like receptor-4 signaling in acute stroke.
