چکیده

post-traumatic stress disorder (ptsd) is a syndrome causing from a severe traumatic happening that leads to threatened death or injury. ptsd is associated with changes in limbic, hippocampal, and prefrontal cortical region function due to changes in synaptogenesis, dendritic modifying, and neurogenesis. changes in neuron in ptsd patients result from pathophysiological disturbances in inflammatory, metabolic, and apoptic processes. brain-derived neurotropic factor (bdnf) is a neurotrophin that functions as survivorship factor for selected neurons of central nervous system and it can regulate synaptic plasticity, memory processes and behavior in the limbic system. failure to produce bdnf in the brain can lead to a variety of central nervous system disorders. researches indicate that impairment in the regulation of neural bdnf occurs in conditions of ptsd. it is found that level of bdnf in serums of ptsd patients were lower as compared to related controls. it is suggested that bdnf may be involved in pathophysiology of ptsd and enhancing bdnf-related signaling and restoring level of bdnf in serum may be considered as consequently therapeutic.

Assessment of oxidative stress parameters of brain-derived neurotrophic factor heterozygous mice in acute stress model

Objective(s): Exposing to stress may be associated with increased production of reactive oxygen species (ROS). Therefore, high level of oxidative stress may eventually give rise to accumulation of oxidative damage and development of numerous neurodegenerative diseases. It has been presented that brain-derived neurotrophic factor (BDNF) supports neurons against various neurodegenerative conditio...
