In the diabetic retina disruption of fractalkine (FKN) signaling induces fibrin(ogen) deposition. increased production of IL-1??? by microglia. vascular and neuronal damage.But. how FKN and its receptor. CX3CR1. regulate microglia activation and retinal pathology is unknown.In humans. two single nucleotide polymorphisms in the CX3CR1 locus (hCX3CR1-I249/M280) that show defective binding to FKN. play a key role in inflammation during diabetes.Induction of diabetes in a mouse model expressing the human CX3CR1-I249/M280 revealed accelerated neuronal loss in the retina.
