Front Pharmacol. 2019 Nov 15:10:1362. doi: 10.3389/fphar.2019.01362. eCollection 2019.

Abstract

Obsessive compulsive disorder (OCD) is a heterogeneous psychiatric disorder affecting 1%-3% of the population worldwide. About half of OCD afflicted individuals do not respond to currently available pharmacotherapy, which is mainly based on serotonin reuptake inhibition. Therefore, there is a critical need to search novel and improved therapeutic targets to treat this devastating disorder. In recent years, accumulating evidence has supported the glutamatergic hypothesis of OCD, and particularly pointing a potential role for the neuronal glutamate transporter EAAT3. This mini-review summarizes recent findings regarding the neurobiological basis of OCD, with an emphasis on the glutamatergic neurotransmission and EAAT3 as a key player in OCD etiology.

Keywords: EAAT3; NMDAR; OCD; SLC1A1; animal model; glutamate transporter; obsessive-compulsive disorder; synaptic function.
