The ability to detect odorous chemicals in the environment is the oldest of the senses necessary for survival, from escaping danger, finding mates, to locating food. It is said that humans can identify and discriminate up to a trillion different odor mixtures. For chemoreception to have such a high discriminatory power, would require a diverse population of cells dedicated for odor detection. These detector cells are the olfactory sensory neurons (OSNs), which express odorant receptors (ORs) that bind to chemical odors in the environment. In order to increase specificity and sensitivity, an essential property in olfaction is for each OSN …

Brain ischemia is a major cause of debilitation and death in the United States. Excitotoxicity, a condition that arises from the accumulation of glutamate (Glu) in the synapse that leads to overactivation of Glu receptors (GluRs), is the major mechanism of neuronal damage in brain ischemia / stroke. Although it is commonly acknowledged that over activation of GluRs leads to neurodegeneration, it has been recently shown that even during excitotoxicity Glu has a concurrent important role in regulating neuroprotection. GluR-activated transcription factors seem to mediate this neuroprotection, but it remains unclear which signaling cascades and transcription factors are regulated by …
