Stabilized Interleukin-6 receptor binding RNA aptamers.

ABSTRACT: Interleukin-6 (IL-6) is a multifunctional cytokine that is involved in the progression of various inflammatory diseases, such as rheumatoid arthritis and certain cancers; for example, multiple myeloma or hepatocellular carcinoma. To interfere with IL-6-dependent diseases, targeting IL-6 receptor (IL-6R)-presenting tumor cells using aptamers might be a valuable strategy to broaden established IL-6- or IL-6R-directed treatment regimens. Recently, we reported on the in vitro selection of RNA aptamers binding to the human IL-6 receptor (IL-6R) with nanomolar affinity. One aptamer, namely AIR-3A, was 19 nt in size and able to deliver bulky cargos into IL-6R-presenting cells. As AIR-3A is a natural RNA molecule, its use for in vivo applications might be limited due to its susceptibility to ubiqu
