| Outline of Final Research Achievements |
Neuroinflammation and neuroplasticity contribute to the pathogenesis of major depression (MD) as well as response to antidepressant(s). In this study, in order to identify responsibility genes to antidepressant, we examined an association between polymorphisms of 161 single nucleotide polymorphisms in the 34 candidate genes and the therapeutic effect of antidepressant (SSRI or SNRI) at the period of 8-week treatment using 105 Japanese MD patients. We identified 9 SSRI-resistant responsibility genes and 2 SNRI-resistant responsibility genes.
Genetic test revealed that the best combination of polymorphisms of FRS3 and RET is useful as a biomarker for identifying non-responders to SSRI after 8-weeks treatment. Moreover, since the dual-luciferase assay showed the difference in transcriptional activity between C allele and G allele of rs1061624 in TNFRSF1B in Jurkat cells, this receptor may become a target molecule for a novel drug against SSRI-resistant MD patients.
