Brain-Derived Neurotrophic Factor Delivered Intranasally Relieves Post-Traumatic Stress Disorder Symptoms Caused by a Single Prolonged Stress in Rats.
Introduction: In our previous study, we successfully constructed the recombinant brain-derived neurotrophic factor (BDNF)-adeno-associated virus (AAV) modified by the influenza virus hemagglutinin-2 (HA2) and trans-transcriptional activator (TAT). BDNF-HA2TAT/AAV has been confirmed to have antidepression effects. BDNF-HA2TAT/AAV seems a promising therapy for post-traumatic stress disorder (PTSD) as the BDNF plays an important role in the function of the nervous system. However, the effects of BDNF-HA2TAT/AAV on PTSD caused by the single prolonged stress (SPS) model are unknown.
Methods: After the SPS model was established, BDNF-HA2TAT/AAV was administered (1 × 1011 vg per rat) through inhalation in the SPS + BDNF group for 2 weeks. Next, the rats underwent behavioral tests including an open-field test (OFT), elevated plus maze (EPM), and a forced swimming test (FST). Sera and hippocampi were obtained from the rats, and an enzyme-linked immune sorbent assay was performed to determine corticosterone concentration. Western blotting was conducted to determine BDNF, tyrosine kinase receptor B (TrkB), cAMP-response element-binding protein, and protein kinase B levels.
Results: BDNF-HA2TAT/AAV released anxiety-like and depression-like behaviors in OFT, EPM, and FST. BDNF-HA2TAT/AAV also results in high plasma concentrations of corticosterone, BDNF, and TrkB in the hippocampus.
Conclusions: SPS is an excellent animal model to assess PTSD. BDNF-HA2TAT/AAV therapeutically effects PTSD caused by SPS, with changes seen in plasma corticosterone and BDNF-TrkB pathways within the hippocampus; therefore, BDNF-HA2TAT/AAV may be a promising treatment for patients with PTSD.
期刊介绍：
The biological approach to mental disorders continues to yield innovative findings of clinical importance, particularly if methodologies are combined. This journal collects high quality empirical studies from various experimental and clinical approaches in the fields of Biological Psychiatry, Biological Psychology and Neuropsychology. It features original, clinical and basic research in the fields of neurophysiology and functional imaging, neuropharmacology and neurochemistry, neuroendocrinology and neuroimmunology, genetics and their relationships with normal psychology and psychopathology. In addition, the reader will find studies on animal models of mental disorders and therapeutic interventions, and pharmacoelectroencephalographic studies. Regular reviews report new methodologic approaches, and selected case reports provide hints for future research. ''Neuropsychobiology'' is a complete record of strategies and methodologies employed to study the biological basis of mental functions including their interactions with psychological and social factors.
