A study found that Parkinson's disease is associated with immune system and it proposes development of new drugs for the treatment of the disease.

A genetic link was found in the human leukocyte antigen (HLA) region which is associated with Parkinson's disease and this region is compactly occupied with genes related to immune system function, confirmed by Johns Hopkins researchers from the Center for Inherited Disease Research.

Kimberly Doheny said that Genome-wide association study (GWAS) has founded an interesting discovery, which is based on the whole genome and related to discover what genes might be related to Parkinson's disease.

Haydeh Payami said that this discovery has directed the path of research and shown the genetic link with immune system.

According to the study, Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are helpful in the treatment of Parkinson's disease, although it might benefit different people with different degree.

Researchers also found that (NSAIDs) give different amount of benefits to different people depending on the genes. More selective medicines can be formed by investigating the link between Parkinson's disease and inflammation in the framework of the genetic differences in different individuals.

The findings of the study are published in Nature Genetics.
