Team "Serotonin and Physiopathologies"
Summary
par - 26 novembre 2012
Group leader : Philippe MARIN, DR2 CNRS
RESEARCH INTERESTS
Serotonin (5-hydroxytryptamine, 5-HT) is a major neurotransmitter of the mammalian central nervous system. Serotonin is involved in numerous physiological functions including the regulation of mood, cognitive functions, feeding, sleep and pain transmission. Alterations of serotonergic systems have been involved in numerous psychiatric disorders such as mood disorders and psychoses. Accordingly, 5-HT receptors and the serotonin transporter (SERT) are major targets of numerous psychoactive medications including the majority of currently available antidepressants and atypical antipsychotics. Using functional proteomics approaches, our team identifies signalling networks associated with various 5-HT receptors and the 5-HT transporter and characterizes their role in synaptic transmission and synaptic plasticity, cognition, mood and neuronal survival.
The team is affiliated to FondaMental (the network for scientific collaboration in mental health).
The team is supported by The French National Research Agency, the Languedoc-Roussillon Region, the France Alzheimer Association and the European Ligue against Alzheimer’s Disease.
