TAT-EE3
Based on 1 Customer Validation
TAT-EE3 is a neuroprotective peptide which can uncouple TRPM2-NMDARs interaction. TAT-EE3 inhibits TRPM2-induced enhancement of NMDAR surface expression and current amplitude.TAT-EE3 protects neurons against ischemic injury in vitro and in vivo. TAT-EE3can be used for the study of ischemic stroke.

Biological Activity
TAT-EE3 (10 μM, overnight) disrupts the interaction between TRPM2 and GluN2a/GluN2b in HEK293T cells and neurons, inhibits TRPM2-induced enhancement of NMDAR surface expression and current amplitude[1].
TAT-EE3 (10 μM, overnight) reduces OGD-induced intracellular Ca2+ overload, neuronal death, and mitochondrial depolarization in wild-type neurons, but has no effect on gM2KO neurons[1].
TAT-EE3 (10 μM, 30-90 min) eliminates PMA-induced NMDAR current potentiation in wild-type neurons, without additional inhibition in gM2KO neurons[1].

Animal Model:Focal cerebral ischemia models were constructed by performing right middle cerebral artery occlusion (MCAO) on 8-9 week-old male mice, with 120 minutes of occlusion followed by 24 hours of reperfusion, or 60 minutes of occlusion followed by 7 days of reperfusion[1]
-
Dosage:0.33 mg/kg (100 nmol/kg)
-
Administration:i.p. repeated every 12 h after MCAO for 7 days
-
Result:Reduced infarct volume.
Inhibited MCAO-induced increase in NMDAR surface expression in wild-type mice, but did not exert further Protective effects in neuron-specific TRPM2 knockout (nM2KO) mice.
Improved long-term neurological deficit scores and rotarod test performance in mice.
Maintained the phosphorylation levels of ERK1/2 and CREB in the brain.
