BACKGROUND: In stressful situations, a person's ability to appropriately complete tasks with minimal anxiety is known as stress resilience. Genetic variants in neuropeptide Y, Corticotropin releasing hormone receptor 1 (CRHR1), and serotonin transporter have been previously reported to be associated with low resilience, but the relationship between low resilience and the dopaminergic signalling pathway is not well understood. Here, we aimed to describe the association between comprehensive psychological characteristics and messenger RNA levels of dopamine receptor D1 (DRD1), dopamine receptor D2 (DRD2), dopamine receptor D3 (DRD3), dopamine receptor D4 (DRD4), dopamine receptor D5 (DRD5), COMT, Dopamine Beta-Hydroxylase (DBH), Tyrosine hydroxylase (TH), monoamine oxidase A (MAOM), dopa decarboxylase (DDC), dopamine transporter (DAT), serotonin transporter (5-HTT), brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) genes based on peripheral blood samples from 400 subjects who react differently to major life event stressors...
