Microglia: Immune Network in the CNS

Abstract
In recent years much progress has been made toward a better understanding of the nature and function of microglial cells. This review summarizes new developments and attempts to provide a perspective for future avenues to take in microglial research. Microglia are considered to play an active role in a variety of neurological diseases. Their function in forming a network of immune competent cells within the CNS is discussed.
