Method of preventing acute or sub-acute hepatic failure by administering a long-acting recombinant human soluble tumor necrosis factor alpha receptor II fusion protein
The present invention belongs to the field of the application of genetic engineering and gene function, and it is directed to a new medical use of the gene encoding the recombinant soluble tumor necrosis factor α receptor (HusTNFR). The present invention made intervention to fulminant hepatic failure in mice by use of the long-acting recombinant human soluble tumor necrosis factor αreceptor and the classic animal models of acute and sub-acute hepatic failure. The results showed that the long-acting soluble tumor necrosis factor αreceptor of the present invention has a half-life extended more than 10 times, and it significantly decreased the mortality of model animals and has superior therapeutic effect for the treatment and/or prophylaxis of acute and sub-acute hepatic failure in model animals. These receptors have a noticeable therapeutic effect for the treatment and/or prophylaxis of acute and sub-acute hepatic failure in comparison with the non-long-acting HusTNFR.
