Abstract:
Objective To study on the relationship between plasminogen and brain-derived neurotrophic factor(BDNF),and explain the molecular mechanism of depression ,then provide new clew for diagnosis and treatment of depression .Methods The chronic unpredictable mild depression rat mode was established ,then depression symptoms including absence of delight ,the decline of actions and activities ,and weight reduction of rat were tested .The levels of individual plasminogen and BDNF in hippocampus were determined by Western blot .Results The expression of BDNF and plasminogen in depression rat mode and control group was significantly different(P<0 .01) ,and there was a positive correlation between BDNF and plasminogen(r=0 .65 ,P<0 .01) .Accord-ing to the linear-regression analysis ,there was a dependence relationship between them(r2 =0 .423) .The equation of regression was YBDNF=0 .750XPlasminogen +0 .201 .Conclusion Stress could affect the growth and survival of nerve cell ,which lead to the depression behavior of rats ,meanwhile ,the decline of plasminogen and BDNF levels ,the positive correlation between them illustrate that plas-minogen and BDNF take part in the mechanism of depression .
