Abstract
The present invention provides for nucleic acids improved for the expression of interleukin-15 (IL-15) in mammalian cells. The invention further provides for methods of expressing IL-15 in mammalian cells by transfecting the cell with a nucleic acid sequence encoding an improved IL-15 sequence. The present invention further provides expression vectors, and IL-15 and IL 15 receptor alpha combinations (nucleic acid and protein) that increase IL-15 stability and potency in vitro and in vivo. The present methods are useful for the increased bioavailability and biological effects of IL-15 after DNA, RNA or protein administration in a subject (e.g. a mammal, a human).
