摘要
It has been suggested that neuropeptide Y (NPY) is involved in the pathophysiology of depression. Plasma peptide-rich fraction from patients with major depressive disorder and control subjects was eluted with high performance liquid chromatography (HPLC), followed by radioimmunoassay of NPY. The screening patterns of the NPY-like immunoreactivity in 50 fractions eluted by HPLC from the plasma peptide-rich fraction were different between the two groups. The values of NPY in the 16 controls and the 14 patients were 427 +/- 38 and 310 +/- 27 fmol/ml plasma (P < 0.05), respectively. These results suggest that impaired metabolism of plasma NPY and the reduced plasma NPY in patients with major depressive disorder could be involved in the pathogenesis or pathophysiology of major depressive disorder.
