General description

Glutamate is a major excitatory neurotransmitter used as a signaling molecule between nerve cells and is involved in most aspects of normal brain function including cognition, learning and memory. Various glutamate receptors are found throughout the brain and include NMDA, AMPA/kainate and metabotropic receptors (mGluR). Normal glutamate levels are essential for normal brain function, however high levels may result in over-excitation of nerve cells, leading to eventual cell damage and/or cell death. Glutamate-induced cytotoxicity has been implicated in neurodegenerative disorders such as Alzheimer’s disease, Huntington’s disease and Parkinson’s disease along with other conditions including spinal cord injury and multiple sclerosis. Therapies that may inhibit or reduce the effects of glutamate activity are thus of great therapeutic interest.
HT-22 is an immortalized mouse hippocampal cell line subcloned from the HT-4 cell line . The parental HT-4 cell line was derived from the immortalization of mouse neuronal tissues with a temperature sensitive SV40 T-antigen . HT-22 is highly sensitive to glutamate and is thus frequently used as a model system to study glutamate-induced toxicity in neuronal cells.

A neuronal cell line, HT-22, is sensitive to glutamate cytotoxicity via a non-receptor mediated oxidative pathway. 12-O-tetradecanoylphorbol-13-acetate (TPA), an activator of protein kinase C, blocks this glutamate-induced cell death. Down-regulation of protein kinase C eliminates the protection against glutamate cytotoxicity...
