Outline of Final Research Achievements

Depression-like behavior is often complicated by chronic pain. However, little is known about neurotrophic factor(BDNF) mediated preventing effect on mood disorder in chronic pain and its molecular mechanisms. We aimed to investigate the effects of magnetic field stimulation(MFS) and 4-methycatechol(4-MC) based on brain-derived neurotrophic factor (BDNF)-mediated signaling and gene expression in chronic pain. Both MFS and 4-MC ameliorated chronic pain and pain-related negative emotion by normalizing the induction of BDNF . These results suggest that MFS and 4-MC may represent the additional strategies against chronic pain associated with depression.
