There is already considerable preclinical data demonstrating the therapeutic potential of Y1R agonists and Y2R antagonists for the treatment of stress-related disorders and these targets clearly merit additional study. Elucidating the neuroanatomical interactions of the NPY system with other neurotransmitters and peptides within stress-integrative circuitry would greatly advance our knowledge regarding the role of NPY in stress resilience and emotionality in future studies. In addition, future studies should consider the impact of sex differences http://www.selleckchem.com/products/Cyclopamine.html on NPY-mediated effects. Human
and rodent studies indicate that females may be more vulnerable to stress and stress-related psychiatric diseases than buy Doxorubicin males (Bangasser and Valentino, 2014). Psychiatric symptomology and treatments responses also vary based on sex (Kokras and Dalla, 2014). Future studies examining the efficacy of NPY on stress and emotionality in females with direct comparisons to males would advance our understanding of sex differences in stress resilience. Neuroanatomical and molecular studies conducted across sexes would reveal potential mechanisms underlying effective coping to stress and intervention strategies for stress-induced psychiatric diseases.

“Glucocorticoid hormones play a fundamental role in the adaptation of an organism to stressful events in its life. Research over the past >60 years has shown that glucocorticoid hormone actions at the molecular and cellular level are highly complex with multiple Adenosine long-term consequences for physiology and behavior (De Kloet and Reul, 1987, De Kloet et al., 1998, De Kloet et al., 2005, McEwen, 2012a and McEwen, 2012b). Not surprisingly, research has provided
ample evidence that chronic hyper- as well as hypo-secretion of glucocorticoid hormones is involved in the development of a range of metabolic, immune, endocrine and neuro-psychiatric disorders. The psychiatric diseases include stress-related disorders like major depression and anxiety disorders (e.g. post-traumatic stress disorder (PTSD)). During the past 15 years this idea has been supported by evidence that individual differences exist in the vulnerability of developing a major depressive or anxiety disorder during the course of life (Zannas and Binder, 2014). It appears that certain genetic traits, e.g. SNPs in the glucocorticoid receptor (GR; Nr3c1) associated chaperone Fkbp5 (FK506-binding protein 51) gene, in combination with traumatic (early) life events can dramatically increase the likelihood of precipitating psychiatric disease (Klengel and Binder, 2013a and Klengel and Binder, 2013b).
