When the drugs don't work: the potential of glutamatergic antipsychotics in schizophrenia — ADDENDUM-article.

2006-11-14 · Ungless et al., 2001 : The first in a series of papers to observe a form of long-term synaptic plasticity of glutamatergic synapses in the VTA in response to addictive drugs. This and other adaptive changes common to several addictive drugs downstream of the dopamine increase are the focus of much current research.

Evidence from postmortem and in vivo brain imaging studies implicates amino acid neurotransmitter systems in the pathophysiology of MDD. Glutamatergic neurons produce glutamate, which is one of the most common excitatory neurotransmitters in the central nervous system (CNS). It plays a critical role in fundamental processes, such as learning, cognition, and memory, and dysregulation of glutamatergic transmission can result in several neurological conditions. ioGlutamatergic Neurons are compatible with plates ranging from 6 to 384 wells and are available in two vial sizes, tailored to suit your experimental needs with minimal waste. Recommended seeding density for ioGlutamatergic Neurons is 30,000 cells/cm 2, compared to up to 250,000 cells/cm 2 for other available products on the market. AUTHORS' CONCLUSIONS In general, all glutamatergic drugs appeared to be ineffective in further reducing positive symptoms of the disease when added to the existing antipsychotic treatment. Glycine and D-serine may somewhat improve negative symptoms when added to regular antipsychotic medication, but the results were not fully consistent and data are too few to allow any firm conclusions. 2016-03-17 · Glutamatergic projections to and from the various frontal sub-regions (OFC, infralimbic cortex and prelimbic cortex) to the striatum play a key role in the regulation of various compulsive behaviours in humans including: (1) the feeling of loss of control (OCD), (2) repetitive motor behaviours (stereotypy in ASD), and (3) a maladaptive habitual pattern (addiction).

Schizophrenia is a severe psychiatric disease characterised by positive symptoms such as hallucinations and delusions and negative symptoms such as blunted affect and emotional withdrawal.

The modulatory effect of the glutamatergic system on the effects of analgesic drugs used in neuropathic pain therapy Glutamate receptors Neuropathic pain has often been classified as opioid resistant, because it can be only partly relieved by high doses of opioids; such a phenomenon is also observed in animal models ( Ossipov et al . 1995 ; Mika et al . 2007 ).

Examples include excitatory amino acid receptor agonists, excitatory amino acid receptor antagonists, and excitatory amino acid reuptake inhibitors . Glutamatergic system represents a target for effective intervention in major depression. Specifically, those glutamatergic medications targeting NMDA receptors by inhibiting the release of neurotransmitters or modulating its post-synaptic responses may serve as molecule modulators with specific anti … In general, all glutamatergic drugs appeared to be ineffective in further reducing positive symptoms of the disease when added to the existing antipsychotic treatment. Glycine and D-serine may somewhat improve negative symptoms when added to regular antipsychotic medication, but the results were not fully consistent and data are too few to allow any firm conclusions.

Several compounds approved for other indications, however, have been identified as additionally affecting glutamate neurotransmission. glutamatergic drug development (Figure 1).

These and other atypical antipsychotic drugs can be used together to inhibit excessive excitability in pyramidal cells, decreasing the symptoms of schizophrenia. Currently available antipsychotic drugs target dopaminergic neurotransmission. Many patients do not respond fully to these treatments, and there has been considerable effort to investigate alternative targets. Here we summarise the rationale and recent evidence supporting efforts to develop glutamatergic antipsychotic drugs.

The past decade has witnessed a growing body of preclinical and clinical evidence that glutamatergic systems may play a pivotal role in drug dependence.

Acamprosate (calcium acetylhomotaurine) is derived from homotaurine, a nonspecific γ-aminobutyric acid 2.2. N-acetylcysteine (NAC). NAC is an N-acetylated derivative of the naturally occurring amino acid It has been hypothesized that glutamatergic drugs may be of benefit to the 20–30% of individuals with schizophrenia who fail to show any response to dopaminergic agents, and may be particularly useful in the early stages of the illness, where they may be disease-modifying. 2003-05-09 · When drug-taking is initiated, dopaminergic and glutamatergic neurotransmission in the mesocorticolimbic system is activated.

Pharmacologic agents that modulate GABAergic neurotransmission, including benzodiazepines and barbiturates, are drug classes of major clinical importance. In comparison, pharmacologic agents targeting glutamatergic neurotransmission remain largely experimental. Synaptic vesicle protein 2A (SV2A), the target of the antiepileptic drug levetiracetam (LEV), is expressed ubiquitously in all synaptic terminals. Its levels decrease in patients and animal models of epilepsy. Thus, changes in SV2A expression could be a critical factor in the response to LEV. Epilepsy is characterized by an imbalance between excitation and inhibition, hence SV2A levels in Moreover, it influences several panic-related neurotransmitters, such as serotonin and noradrenaline.
