IL6 and Cerebral ischemia: We assessed the inflammation in the cerebral circulation by characterization of neutrophils and monocytes and measurement of cytokines IL-1β, IL-6, IL-8, IL-10, TNFα, sVCAM-1 and MCP-1, as these markers are known to respond within hours after cerebral ischemia[1,3,7,8,10-14,16-20].
