Psychiatric disorders and Nesfatin-1<p>Psikiyatrik hastalıklar ve Nesfatin-1
Journal Title: Journal of Human Sciences - Year 2015, Vol 12, Issue 1
Abstract
Nowadays psychiatric disorders is complex group of diseases that many factors play a role in the etiology and prevalence of it's very higher. Neurotransmitters levels such as serotonin norepinefrin and dopamine in the brain is changed in case of illness. For instance Neurotransmitters such as serotonin, norepinefrin and dopamine is decreased in depression and dopamine is increased in schizophrenia. Many of the antidepressants drugs that used in the treatment of depression leads to weight gain in patients. Nesfatin-1 is expressed that recently discovered, being an anorexigenic peptid and derived NEFA / nukleobindin2 (NUCB2) in the brain's stress-related field. Plasma nesfatin-1 levels were found to be very high psychiatric patients than normal people with. Peptids' brings to mind the idea that may be important in the prognosis of the disease which the decreased of the level of hormone following treatment process and high in case of illness. It's will provide a better understanding of the prognosis of the disease that can also be explained the effect of these hormones under stress in this disease. In future studies, to understand the antidepressants effect of nesfatin-1 the important molecular mechanisms related with the nesfatin-1 receptor should be necessary to define. In light of recent studies, it is thought that nesfatin-1 could be a important antidepressant drug in the near future.Özet Psikiyatrik hastalıklar günümüzde prevalansı çok yüksek olan etiyolojisinde birçok faktörün rol oynadığı yaygın ve kompleks bir hastalık grubudur. Hastalık durumunda beyinde serotonin, norepinefrin, dopamin gibi nörotransmitterlerin düzeyleri değişmektedir. Örneğin depresyonda serotonin, norepinefrin ve dopamin azalmaktayken; şizofrenide ise dopamin artmaktadır. Major depresyon tedavisinde kullanılan antidepresan ilaçların çoğu hastalarda kilo alımına yol açmaktadır. NEFA/nukleobindin2 (NUKB2)'den kaynaklanan son yıllarda keşfedilen anoreksijenik bir peptid olan nesfatin-1, beynin stresle alakalı alanlarında bulunmaktadır. Psikiyatrik hastalarda normal insanlara kıyasla plazma nesfatin-1 düzeyi çok yüksek bulunmuştur. Hastalık durumunda yüksek iken, tedavi sürecini takiben hormon seviyesinin düşmesi peptidin hastalığın prognozunda önemli olabileceği fikrini akla getirmektedir. Bu rahatsızlıklarda stres altında bu gibi hormonların etkilerinin açıklanması hastalığın prognozunun daha iyi anlaşılmasını sağlayacaktır. Gelecek çalışmalarda, nesfatin-1'in antidepresif etkisini anlamak için; nesfatin-1 reseptörleri ile ilgili önemli moleküler mekanizmaların tanımlanması gerekmektedir. Son yapılan çalışmaların ışığında, nesfatin-1'in yakın gelecekte önemli bir antidepresan ilacı olabileceği düşünülmektedir.
