Since MyD88 is a convergence point for signaling pathways of the innate immune system (including Toll-Like Receptors (TLRs) and interleukin-1ß (IL-1ß)), the purpose of this study was to assess the role of MyD88 and its dependent pathways on abnormalities that develop in retina and white blood cells related to diabetic retinopathy. This evidence concerns the gene MYD88 and diabetic retinopathy.
