The press release today by the Boston Children's Hospital seems newsworthy.

Targeting a rogue T cell prevents and reverses multiple sclerosis in mice

First three paragraphs:


Multiple sclerosis is an autoimmune disease affecting both adults and children. It's driven by "helper" T cells, white blood cells that mount an inflammatory attack on the brain and spinal cord, degrading the protective myelin sheath that covers nerve fibers. But there are many different kinds of T helper cells, and up until now, no one knew which ones were the bad actors.

Researchers at Boston Children's Hospital have now pinpointed the specific helper T cells that cause MS, as well as a protein on their surface that marks them. As reported this week in PNAS, an antibody targeting this protein, CXCR6, both prevented and reversed MS in a mouse model.

If human studies bear out the findings, targeting these rogue T cells could potentially ameliorate MS, says senior investigator Eileen Remold-O'Donnell, PhD, of the hospital's Program in Cellular and Molecular Medicine. She believes the findings could also apply to other forms of autoimmune encephalomyelitis (inflammation of the brain and spinal cord), as well as inflammatory arthritis.
