employed liposomes for delivering hnRNP A2/B1 siRNA.[191] RT‐qPCR and ELISA analysis revealed that hnRNP A2/B1 siRNA/lipoplexes effectively reduced hnRNP A2/B1 protein and mRNA levels (up to 50%) but also efficiently dampened IL‐23 and TNF‐α levels in monocytes/macrophages, resulting in mitigated inflammation, bone erosion and arthritis symptoms, as well as a decreased incidence of arthritis. The gene discussed is TNF; the disease is Arthritis.
