Scientists find that microRNA affects inflammation in lupus disease

Researchers from Nagoya University have identified two microRNAs that are downregulated in systemic lupus erythematosus, a disease where the immune system attacks itself. The study found that these miRNAs regulate the same set of genes through 'seed overlap' co-targeting, which negatively regulates inflammatory cytokine production.
