Sinauer Associates, Inc. [2]. Several lines of evidence suggest that derangements in the control of local glutamate concentration and signaling at various glutamatergic receptors promote glioma viability and growth. What both receptor types have in common is that they are activated by specific neurotransmitters. In this context, it is interesting that strong negative cooperativity between the individual binding sites exists (Suzuki et al 2004), thus presumably ensuring that only one binding site is occupied. Psychopharmacology Metabotropic glutamate receptors (mGlus) are coupled to a variety of second messenger systems via G proteins. Moreover, excessive glutamate release has been implicated in neuronal cell death.
