Isolated nucleic acid molecules encoding T cell inducible factors or interleukin 21, proteins encoded by them and uses thereof

摘要

The invention involves isolation of nucleic acid molecules, the expression of which are up-regulated by interleukin-9. The amino acid sequences of the proteins which correspond to the nucleic acid molecules show some structural features of cytokines. In addition to the nucleic acid molecules and the proteins, various uses of the molecules are disclosed. The molecules are referred to as T cell inducible factors. The molecules are implicated in activation of STAT molecules, acute phase proteins and inflammation.
