Zhang J, Liu G, Chen D, et al. - Researchers focused on the impact of regulatory T cells (Tregs) and CCR5+ Tregs on the prognosis of ischemic stroke. For this purpose, blood samples from patients were analyzed to measure Tregs and CCR5+ Tregs. They found higher Tregs in patients suffering from severe ischemic stroke vs those in mild ischemic stroke, while the expression of CCR5+ Tregs were reversed. A good predictive impact of Tregs and CCR5+ Tregs on the prognosis of ischemic stroke was revealed in the univariate and multivariate logistics regression analysis. By ROC curve, a better prediction impact was achieved by the combination of Tregs and CCR+ Tregs. Based on these data, experts suggested the utility of the combination of Tregs and CCR5+ Tregs as biomarkers for the prognosis of ischemic stroke.
