"“This all comes down to immune system and brain interaction,” said Kipnis, chairman of UVA’s Department of Neuroscience. “The two were believed to be completely not communicating, but now we’re slowly, slowly filling in this puzzle. Not only are these [immune] cells present in the areas near the brain, they are integral to its function. When the brain is injured, when the spinal cord is injured, without them, the recovery is much, much worse.” Curiously, the immune cells were found along the vessels discovered by Kipnis’ team. “They’re right on the lymphatics, which is really weird,” noted researcher Sachin Gadani. “You have the lymphatics and they’re stacked right on top. They’re not inside of them – they’re around them.”" The meningeal space is occupied by a diverse repertoire of immune cells. Central nervous system (CNS) injury elicits a rapid immune response that affects neuronal survival and recovery, but the role of meningeal inflammation remains poorly understood. Here, we describe type 2 innate lymphocytes (ILC...
