"We found that a common link exists between the fibrosis in different organs affected in scleroderma, specifically skin, lungs, GI tract, and peripheral blood cells. That common link is a certain type of cell of the innate immune system that we think is driving the disease....
What’s important about our discovery is that almost every drug currently used to treat scleroderma targets the adaptive immune system, by targeting T cells and B cells, and not those innate immune cells. So fundamentally, the drugs that are being used to treat scleroderma, in most cases, are probably not targeting these important cells."
