Excerpted from article:...In 2016, Dritan Agalliu, PhD, an assistant professor in the Department of Neurology at Columbia University Medical Center in New York City, published a study showing that immune cells produced in the nose after multiple strep infections appear to be the culprit for the disease [known as pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections, or PANDAS].These cells enter the brain via the nerves that are responsible for the sense of smell, and they damage the blood vessels and synapses in the brain.
Agalliu says this research helped explain a crucial step in the disease: how antibodies that the body makes to attack strep or other infections cross the blood/brain barrier in these children and attack parts of their brain by mistake; similar to what happens in other autoimmune diseases of the brain, like multiple sclerosis.
The NIHM recently awarded Agalliu nearly $2 million to keep studying the disorder. He says it should be called post-streptococcal basal ganglia encephalitis, or inflammation of the brain. He’s also doing research funded by a private donor, looking at genetic chances of having the disorders to understand why a small number of children who get multiple strep infections are prone to get the disease.
“It is really the brain inflammation that is central to this disease. If we think about PANDAS/PANS this way, it will relieve a lot of controversy and make therapies more acceptable for patients,” Agalliu says. “I am hoping with our next publication, we can alleviate any potential question that this is an autoimmune disease.” [read more]
