Dcf1 Deficiency Attenuates the Role of Activated Microglia During Neuroinflammation

open access: yesFrontiers in Molecular Neuroscience, 2018
Microglia serve as the principal immune cells and play crucial roles in the central nervous system, responding to neuroinflammation via migration and the execution of phagocytosis. Dendritic cell-derived factor 1 (Dcf1) is known to play an important role
