MMP9 and Stroke: Our data show that 3 μg/kg VT treatment significantly decreases inflammatory factor MMP9 expression (Figure 4A, p < 0.05), reduces the number of macrophages (ED1, Figure 4B, p < 0.05), and decreases the number of apoptotic cells (TUNEL, Figure 4C, p < 0.05) in the IBZ after stroke in T1DM rats compared to PBS‐treated control group.
