BACKGROUND: Inflammation is known in atypical parkinsonism (AP), but the role of autoimmunity is unclear. This study evaluates immune system modifications suggesting autoimmunity in AP.
METHODS: Included patients with AP diagnosed at Amrita Institute of Medical Sciences, Kochi (December 2018-May 2019), and age- and sex-matched controls. Fifteen immune parameters, including T regulatory cells, RORγt, and cytokines (IL-2, IL-4, IL-6, IL-10, IL-17A, IL-21, IL-22, IL-23, TNF, IFN-γ, GM-CSF, NF-κB, TGF-β), were assessed in peripheral blood (flow cytometry and ELISA).
RESULTS: Twenty-six cases (mean age 67.8 ± 7.5 years; 16 males) and 15 controls (mean age 68.1 ± 3.5 years; 10 males) studied. Diagnoses included progressive supranuclear palsy (n = 15), multiple system atrophy (n = 1), frontotemporal dementia with parkinsonism (n = 2), and unspecified AP (n = 8). AP cases had significantly higher RORγt (p = 0.041), IL-6 (p = 0.004), TNF (p = 0.020), IL-10 (p = 0.027), and IL-4 (p = 0.048).
CONCLUSIONS: Elevated RORγt and cytokines suggest immune dysregulation and possible autoimmune mechanisms in AP, warranting further investigation.
