RBFOX3 and Stroke: Moreover, the rDb-SB group exhibited less neuronal loss (NeuN positive [NeuN+]) and microglial activation (Iba positive [Iba+]) in the hippocampus and less apoptotic cell death (terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling [TUNEL]) in the cortex than the rDb-Con group after stroke (Fig. 5d).
