  • Patent number: 9644020
    Abstract: The present invention provides a human Tim-3-Ig fusion protein which can block Tim-3 signal pathway, and said Ig fusion protein comprises Tim-3 protein, human Ig fragment, and the linking sequence therebetween. In the present invention, a human Tim-3-Ig gene is obtained by an artificial synthesis process; an expression vector containing the Tim-3-Ig gene is constructed; and the prepared Ig fusion protein is tested in an expression verification experiment, a binding activity experiment, a blocking activity experiment in different cell lines, and in vivo experiments in mice. The human Tim-3-Ig fusion protein prepared in the present invention can be used to treat immunological diseases caused by high expression of Tim-3.

  • Publication number: 20090305975
    Abstract: Disclosed herein is the use of TRAP per se as an active ingredient for the manufacture of a medicament for the treatment of Staphylococcus aureus infection. An exogenous TRAP (native TRAP or recombinant TRAP) per se can effectively inhibit the production of Staphylococcus aureus exotoxins, thereby reducing the pathogenicity of Staphylococcus aureus. In addition, a medicament including TRAP also stimulates the production of corresponding antibodies in human body at the time when it is used to treat Staphylococcus aureus infections, and these antibodies can further inhibit the production of Staphylococcus aureus exotoxins. Such double actions increase the effects of medicament and provide a novel medicament action mode. Moreover, since TRAP functions merely to the toxicity of bacteria but does not affect the growth of bacteria, it cannot make bacteria readily develop drug resistance, and also effective to drug resistant Staphylococcus aureus.
