GAD1 and ischemia: By contrast, ischemia + peptide was associated with a significantly greater density of WFA+ cells (p = 0.003; Figure 4A), GAD+ cells (p = 0.03; Figure 4B), and the percentage of GAD+ neurons expressing WFA (p = 0.004; Figure 4C) in layer 6 of the parasagittal cortex compared with the ischemia + vehicle group.
