56 We are cautiously hopeful that in the current decade much progress will be achieved in developing and implementing pharmacogenomics as a translational clinical tool to improve the outcomes and reduce the risks of antidepressant treatment. Furthermore, novel and robust pharmacogenomic findings would represent the next logical therapeutic

targets for drug development in depression. As examples, recent work by our group has #Ipatasertib keyword# identified phosphodiesterases (PDE11A) and inflammatory mediators (PSMB4, TBX21, and STAT3) as potential novel antidepressant targets.3,54 This way, pharmacogenomics will not only identify predictors of response to existing treatments, it will also have the potential to lead to conceptually novel treatments.
Major Depressive Disorder (MDD) is Inhibitors,research,lifescience,medical typically considered a mental illness, yet pathology associated with MDD is evident in cells and organs throughout the body. For example, MDD is associated with an increased risk of developing atherosclerosis, heart disease, hypertension, stroke, cognitive decline, and

dementia (including Alzheimer’s disease), osteoporosis, immune impairments (eg, Inhibitors,research,lifescience,medical “immunosenescence”), obesity, metabolic syndrome, insulin resistance, and type 2 diabetes,1-4 and individuals who are afflicted both by MDD and one of these diseases have a poorer prognosis than individuals afflicted by either

alone.3 Inhibitors,research,lifescience,medical This increased risk of serious medical diseases is not fully explained by lifestyle choices such as diet, exercise, and smoking, and the reasons for the heightened risk remain unknown.4 Moreover, many of the medical comorbidities seen in MDD Inhibitors,research,lifescience,medical are diseases more commonly seen with advanced age, and MDD has even been characterized as a disease of “accelerated aging.”1,5,6 In this review article, we explore certain biological mediators that are dysregulated in MDD and that may contribute to the depressed state itself, to the comorbid medical conditions, and to “accelerated aging.” Discovering novel pathological mediators in MDD could help identify new targets for treating depression and its comorbid crotamiton medical conditions and could help reclassify MDD as a multisystem disorder rather than one confined to the brain. Theoretical model We propose a model of MDD comprised of certain pathogenic processes that are interlinked and often recursive, that occur in the brain and in the periphery, and that can culminate in cellular damage, cellular aging, and disease.6-10 This model is presented schematically in Figure 1 and is briefly described in this introduction; the individual moderators and mediators are described in greater detail in the remainder of this article.
