Research Statement:

Obsessive compulsive disorder (OCD) is a psychiatric disease. Genetic studies have positively correlated gene variants of SLC1A1 with OCD. SLC1A1 codifies for the neuronal glutamate transporter excitatory amino acid carrier 1 (EAAT3). Our laboratory developed a new mouse model of OCD based in the overexpression of EAAT3 on neurons that receive glutamate inputs (CamKII-EAAT3 OE). As in the disease, CamKII- EAAT3 OE mice display anxiety behaviors and repetitive behaviors. On the other hand, modifications on dopamine neurotransmission underlay the development of OCD.  The objective of my research is to study the impact of EAAT3 overexpression in dopamine neurotransmission and how those modifications can lead to the development of compulsive behavior.
