Author Spotlight: Induced Microglia-Like Cell Technology to Shed Light on the Role of Microglial Dysfunction in Neuropsychiatric Disorders

Our lab at Kyushu University aimed to clarify the roles of microglial dysfunction in various neuropsychiatric disorders. We believe that our iMG cell technology will shed new light on microglial dynamic function and dysfunction at the cellular level in human beyond the limitation of human brain analysis, such as postmortem study and also pet brain studies. Even now, animal experiments are essential to clarify the brain pathophysiology of mental disorders, but it is unclear how well rodent data can be applied to human pathophysiology.

Our human blood-induced iMG cell technology will this gap between rodent data, clinical data, and microglial function and/or dysfunction. Other human-derived cellular disease model, human iPS cell-derived microglia cells are also developed, which need much time and much money to develop and can assess trait markers but not state markers. The advantage of our iMG method is that it is much simpler, less time-consuming, and cost-effective.

We have already revealed several candidate molecular factors by our reverse translational iMG research focusing on neuropsychiatric disorders such as dementia disease, bipolar disorder, fibromyalgia, glioma, and disease. We believe that our iMG cell technology will shed new light on microglial dynamic function and dysfunction at the cellular levels in various neuropsychiatric disorders.
