Neuroimmune Mechanisms of Mood Disorder: A Translational Perspective

Sun. Oct 13, 2019 10:30 AM - 12:10 PM Room 6 (401+402)

Organizer / Chair: Po See CHEN (Department of Psychiatry, College of Medicine and Hospital , National Cheng Kung University, Taiwan), Co-chair: Yasushi KAJII (T-CiRA Discovery, Takeda Pharmaceutical Company Limited, Japan), Discussants: ‌Masaaki IWATA (Division of Neuropsychiatry, Department of Brain and Neuroscience, Tottori University Faculty of Medicine, Japan), Masahiro OHGIDANI (Department of Neuropsychiatry, Kyushu University, Japan)

Psychosocial adverse conditions involving interpersonal processes are among the strongest proximal risk factors for mood disorders. A biologically plausible, multilevel theory that link experiences of social adverse condition with internal neuroimmune mechanisms that drive pathogenesis for mood disorders has been proposed. Central to this neuroimmune mechanism hypothesis is a novel axis of immune-to-brain bidirectional communication that influences mood and behavior. Under social adverse conditions, sympathetic nervous system can up-regulate myelopoiesis, monocyte trafficking and the expression of pro-inflammatory genes encoding a conserved transcriptional response to adversity (CTRA). The elevated pro-inflammatory cytokines caused by central microglia activation and recruitment of monocytes to the brain contribute to development of mood symptoms such as anhedonia, aggression, psychomotor retardation and social-behavioral withdrawal. Previous studies had suggested that the serum CRP, TNF-alpha levels are to be used as a biomarker for mood status and a predictor of treatment response in mood disorders. Clinical trials that used anti-inflammatory medications as adjunct pharmacotherapy in treating mood disorders. Besides, the neuroimmune mechanisms might link mood disorders with multiple system co-morbidities and sequential dementing change. Insights from this theory may thus shed light on understanding of immune-to-brain bidirectional communications, the rôle of psychosocial adverse conditions, the neuroimmune mechanisms of co-morbidities and late life consequence in mood disorders.
