51 results about "Interleukin 11" patented technology

Interleukin 11 (IL-11) is a protein that in humans is encoded by the IL11 gene. IL-11 is a cytokine and first isolated in 1990 from bone marrow-derived fibrocyte-like stromal cells. It was initially thought to be important for hematopoiesis, notably for megakaryocyte maturation, but subsequently shown to be redundant for platelets, and for other blood cell types, in both mice and humans. It is also known under the names adipogenesis inhibitory factor (AGIF) and was developed as a recombinant protein (rhIL-11) as the drug substance oprelvekin.

Purpose of porcine interleukin 11 in resisting porcine epidemic diarrhea virus infection

The invention relates to a porcine interleukin 11, and a purpose of the porcine interleukin 11 in resisting porcine epidemic diarrhea virus infection. After porcine epidemic diarrhea virus infection happens, a piglet intestinal tract secretes cell factor porcine pIL-11 which is obviously improved, and the expression of the cell factor exhibits high correlation with a virus infection level. The invention discloses a prokaryotic expression plasmid for constructing a recombinant pIL-11, a transformed escherichia coli BL21, and a specific method for obtaining a high-purity recombinant pIL-11 through purification. The recombinant pIL-11 can inhibit the infection of the PEDV (Porcine epidemic diarrhea virus) for a host cell, and has obvious dose dependency. The recombinant pIL-11 activates a STAT3 (signal transducer and activator of transcription 3) signal to inhibit host cell apoptosis induced after PEDV infection happens so as to perform a function of resisting virus infection. The porcinesource IL-11 has a function of resisting virus infection and alleviating piglet intestinal tract injury, and is expected to become an effective medicine for resisting PEDV intestinal tract infectionin the future.
