Its unclear whether the immune response is driving the disease or reacting to brain changes already underway. Parkinsons disease is associated with the destruction of nervous system cells, explains Sette. Could they interfere in inflammation and maybe reduce the number of autoimmune T cells?These findings are published in npj Parkinsons Disease. In fact, T cell reactivity to PINK1 peaked during the prodromal stage, well before visible motor symptoms began. You can see that T cell reactivity before diagnosis, Sette says. Thats the chicken-and-the-egg of inflammation in Parkinsons disease. The researchers are now exploring whether some T cells could play a protective role. Tremors, stiffness, and difficulty with coordination often mark its later stages, as nerve cells in parts of the brain deteriorate. This finding could pave the way for earlier diagnosis and potentially better outcomes for patients. Parkinsons disease is best known for affecting movement. While the findings are compelling, they dont yet prove that T cells cause Parkinsons.
