"The next step in this process is to come up with a drug that can target this receptor," said senior author of the study Kirill Martemyanov, from The Scripps Research Institute (TSRI) in the US.
GPR158 was narrowed down as a key player in depression, according to the researchers the protein was found to be elevated in people with major depressive disorder.
For the study, the scientists studied male and female mice with and without GPR158 receptors. As per the findings based on the behavioral tests, both male and female mice with elevated GPR158 show signs of depression following chronic stress.
On the other hand, suppression of GPR158 protects mice from developing depressive-like behaviours and make them tough to deal with stress.
The study revealed that GPR158 affects key signaling pathways involved in mood regulation in the region of the brain called prefrontal cortex, which affects the stress pattern. However, the researchers emphasised that the exact mechanisms remain to be established. The researchers explained that GPR158 is a so-called "orphan receptor". This is because its binding partner/partners are unknown -- with a poorly understood biology and mechanism of action.
