Patent 7371921 was granted and assigned to Japan Science and Technology Agency on May, 2008 by the United States Patent and Trademark Office.
An object of the present invention is to provide a non-human animal model unresponsive to a mycoplasma-derived lipoprotein/lipopeptide, and a method for screening an inhibitor or a promoter for a response to a mycoplasma-derived lipoprotein with the use of the non-human animal model. A non-human animal model whose function of a gene that encodes a protein such as TLR6 that specifically recognizes a mycoplasma-derived lipoprotein is deficient on its chromosome, for example, a TLR6 knockout mouse, is generated. With the use of the non-human animal model unresponsive to a mycoplasma-derived lipoprotein or an immune cell such as a macrophage derived from the non-human animal model, a subject material and a mycoplasma-derived lipoprotein, a response to a mycoplasma-derived lipoprotein in the non-human animal model or the immune cell is measured/evaluated, and then an inhibitor or a promoter for a response to that is screened.
