Powerful and rare type of immune cell could impact Alzheimer’s disease, multiple sclerosis, meningitis – even migraines

University of Virginia School of Medicine researchers have discovered a rare and powerful type of immune cell in the meninges around the brain, suggesting the cells may play a critical but previously unappreciated role in battling Alzheimer’s disease, multiple sclerosis, meningitis and other neurological diseases, in addition to supporting our healthy mental functioning. By harnessing the cells’ power, doctors may be able to develop new treatments for neurological diseases, traumatic brain injury and spinal cord injuries – even migraines.

Further, the researchers suspect the cells may be the missing link connecting the brain and the microbiota in our guts, a relationship already shown important in the development of Parkinson’s disease.

Unexpected Presence

The cells, known as “type 2 innate lymphocytes,” previously have been found in the gut, lungs and skin – the body’s barriers to disease. Their discovery in the meninges, the membranes surrounding the brain, comes as a surprise.

They were found as UVA researcher Jonathan Kipnis explored the implications of his lab’s game-changing discovery last year that the brain and the immune system are directly connected via vessels long thought not to exist.

“These cells are potentially the mediator between the gut and the brain. They are the main responder to microbiota changes in the gut. They may go from the gut to the brain, or they may just produce something that will impact those cells. But you see them in the gut and now you see them also in the brain,” Kipnis said. “We know the brain responds to things happening in the gut. Is it logical that these will be the cells that connect the two? Potentially. We don’t know that, but it very well could be.”

While much more research needs to be done to understand the role of these cells in the meninges, Gadani noted that it’s almost certain that the cells are important in a variety of neurological conditions.

“It would be inconceivable they’re not playing a role in migraines and certain conditions like that,” he said. “The long-term goal of this would be developing drugs for targeting these cells. I think it could be highly efficacious in migraine, multiple sclerosis and possibly other conditions.”
