In addition, almost all cytokine levels were similar (except for IL‐6 TRPM2+/− PD male in the SNc) to respective controls in TRPM2+/− PD and TRPM2−/− PD male and female animals, and lower than the TRPM2+/+ PD group, suggesting that TRPM2 might be involved in the inflammatory response induced by 6‐OHDA (Mean and SEM values for cytokine levels can be found in Table S3). Here, IL6 is linked to Parkinson disease.
