Brain is directly connected to Immune system, says a new breakthrough study


One of the hallmarks of Central Nervous System (CNS) is the absence of a classical lymphatic drainage system. Although many recent studies have suggested that CNS does undergo constant immune-surveillance, the mechanism by which these immune cells enter and exit the CNS is poorly understood. In light of this, a breakthrough discovery by researchers at the University of Virginia School of Medicine seems to have disproved decades of textbook knowledge.
