In the cortex, the expression of the truncated isoform of TrkB (90 KDa) receptors did not show any significant change (P>0.05) after 1-hr ischemia and 24-hr reperfusion in the ipsilateral cortex (102.4% in MCAO+aCSF, 99.8% in MCAO+TAN-67, 92.9% in MCAO+naltrindole, 97.7% in TAN-67 and 103.0% in Naltrindole) (Figure 3 D, F). Here, NTRK2 is linked to ischemia.
