Biological Activity for L-Quisqualic acid
L-Quisqualic acid is a glutamate receptor agonist acting at AMPA receptors and metabotropic glutamate receptors positively linked to phosphoinositide hydrolysis. Sensitizes neurons in hippocampus to depolarization by L-AP6 (the so called 'quis' effect). Also available as part of the Group I mGlu Receptor Tocriset™.

The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.
Major depressive disorder is characterized by depressed mood and a loss of interest and/or pleasure. Updated in 2015 this poster highlights presynaptic and postsynaptic targets for the potential treatment of major depressive disorder, as well as outlining the pharmacology of currently approved antidepressant drugs.
Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
Learning & Memory Poster
Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.
Schizophrenia is a debilitating psychiatric disorder that affects 1% of the worldwide population. This poster describes the neurobiology of Schizophrenia, as well as highlighting the genetic and environmental factors that play a fundamental role in the etiology of the disease. The current and emerging drug targets are also discussed.
