Study identifies a potential cause of Parkinson's disease

Conti and his team were looking for biological pathways that could connect the immune system's inflammatory response to the damage seen in dopaminergic neurons. After searching human genomics databases, the team's attention was caught by a gene encoding a protein known as interleukin-13 receptor alpha 1 chain (IL-13Ra1), as it is located in the PARK12 locus, which has been linked to Parkinson's. IL-13rα1 is a receptor chain mediating the action of interleukin 13 (IL-13) and interleukin 4 (IL-4), two cytokines investigated for their role as mediators of allergic reactions and for their anti-inflammatory action.
