The Role of Kynurenine Pathway Metabolites in Perinatal Depression and Suicidality

The project will determine whether women with altered levels of kynurenine pathway

metabolites are the ones developing depression and suicidal thoughts in pregnancy and the post-

partum period.

No overlap with proposed project

The goal is to understand whether the HPA axis receptor genes associated with the stress response may contribute to the depression-MetS/T2D co-morbidity and/or to metabolic and psychological associated traits. The genes of interest are corticotropin-releasing hormone receptor genes (CRHR1 and CRHR2) and the melanocortin receptor genes (MC1R-MC5R).
