To better profile the recruited stroke patients, as well as volunteers of the control group, we performed the quantification of the serum levels of the main cytokines (IL-6, IL-10, TNFα) and soluble factors (ICAM-1, Leptin, Fas, BDNF, VEGFR2) known to be involved in the pathogenesis and in the brain plasticity that occurs after stroke [5]. The gene discussed is IL6; the disease is Stroke.
