Abstract Parkinson’s disease (PD) is one of the most common neurodegenerative disorders, with neuroinflammation playing a significant role in its etiology and progression. Both central and peripheral immune responses are involved, and evidence suggests a brain-periphery interaction in PD. Changes in leukocyte subpopulations have been observed in PD patients, making the neutrophil-to-lymphocyte ratio (NLR) a relevant marker of peripheral inflammation. Patients with PD have a higher NLR compared to healthy controls, indicating increased peripheral inflammation. This higher NLR suggests that the neutrophil-to-lymphocyte ratio is a useful non-invasive biomarker of systemic inflammation in PD. The peripheral immune response differs among patients based on their genetic background, with those having sporadic and GBA-associated PD showing a higher NLR in contrast to those with LRRK2-associated PD. Furthermore, this elevated peripheral inflammation is associated with dopaminergic neurodegeneration, underscoring the importance of understanding inflammatory processes in the context of PD for better diagnostic and therapeutic strategies.
