GxE study on inflammation and air polution in PD

Both air pollution exposure and systemic inflammation have been linked to Parkinson’s disease (PD). In this study, led by long-time LIGA collaborator Prof. Beate Ritz at UCLA in the USA, we correlated long term traffic related air pollution measures with genetic markers for inflammation. The analyses showed suggestive evidence that a combination of traffic-related air pollution and genetic variation in the IL1B gene may contribute to risk of developing PD. The results were published in the journal Environmental Research.

First genome-wide GxE study in PD published

The LIGA team was part of a collaborative effort where we performed the first ever genome-wide gene-environment interaction (GxE) analysis of pesticide exposure and risk of Parkinson’s disease (PD). The results of this effort suggest that the effect of pesticide exposure on PD risk may be modified by SNPs in the ERCC6L2 gene. This finding needs to be replicated in independent samples before it should be considered as established. The results were published in the journal Parkinsonism and Related Disorders.
