A new type of microglia gene targeting shows TAK1 to be pivotal in CNS autoimmune inflammation

In this study, the authors generate a new mouse model that allows selective genetic targeting of microglial cells. Using this model, they show that elimination of TGF-β-activated kinase 1 (TAK1) specifically in microglial cells reduces pathology in a mouse model of multiple sclerosis by inhibiting NF-κB, ERK and JNK signaling pathways.
