Increased levels of regulatory T cells and IL-10-producing regulatory B cells are linked to improved clinical outcome in Parkinson's disease: a 1-year observational study.

Whilst the contribution of peripheral and central inflammation to neurodegeneration in Parkinson's disease and the role of the immune response in this disorder are well known, the effects of the anti-inflammatory response on the disease have not been described in depth. This study is aimed to assess the changes in the regulatory/inflammatory immune response in recently diagnosed, untreated PD patients and a year after. Twenty-one PD patients and 19 healthy controls were included and followed-up for 1 year.

Increased Tc17 cell levels and imbalance of naïve/effector immune response in Parkinson's disease patients in a two-year follow-up: a case control study.

Background: Neuroinflammation has been proved to play a role in dopaminergic neuronal death in Parkinson's disease (PD). This link highlights the relevance of the immune response in the progression of the disease. However, little is known about the impact of peripheral immune response on the disease.

Immunomodulatory effect and clinical outcome in Parkinson's disease patients on levodopa-pramipexole combo therapy: A two-year prospective study.

Parkinson's disease (PD), the second most frequent neurodegenerative disease, has been linked to increased central and peripheral inflammation. Although the response of the immune system to dopaminergic treatment remains to be fully understood, dopaminergic agonists are known to exhibit immunoregulatory properties which may, at least in part, explain their therapeutic effect in PD. This highlights the need of analyzing immune parameters in longitudinal studies on PD patients receiving specific therapeutic regimes.
