    The peptide neurotransmitter N-acetylaspartylglutamate (NAAG) suppresses glutamate transmission through selective activation of pre-synaptic Group II metabotropic glutamate receptor subtype 3 (mGluR3) after traumatic brain injury (TBI). However, synaptically released NAAG is hydrolyzed to form N-acetylaspartate and glutamate mainly by Glutamate carboxypeptidase II (GCPII), losing neuroprotective effect. In this study, we found that knock out of the GCPII gene is not embryonic lethal and affords histopathological protection with improved long-term behavioral outcomes after TBI.

    JNK/c-Jun pathway is shown to be activated in neurons of the Alzheimer's disease (AD) brain and plays a vital role in neuron death in AD models. However, downstream targets of c-Jun in this disease have not been thoroughly elucidated. Our study shows that two important pro-apoptotic proteins, Bim (Bcl-2 interacting mediator of cell death) and Puma (p53 up-regulated modulator of apoptosis) are targets of c-Jun in Aβ-treated neurons. We demonstrate that the JNK/c-jun pathway is activated, in cultures of cortical neurons following treatment with oligomeric Aβ and in AD transgenic mice, and that inhibition of this pathway by selective inhibitor blocks induction of Puma by Aβ. We have also observed functional co-operation of both JNK and p53 pathway in regulation of Puma under Aβ toxicity. Most importantly, we identified a novel AP1-binding site on rat puma gene which is necessary for direct binding of c-Jun with Puma promoter. Thus, our results suggest that both Bim and Puma are target of c-Jun and elucidate the intricate regulation of Puma expression by JNK/c-Jun and p53 pathways in neurons upon Aβ toxicity.
