摘要:
The present invention provides a transgenic animal expressing the full-length human hepatitis C virus (HCV) for the purpose of constructing a system for screening for a remedy for human hepatitis C. The present invention is a transgenic hepatitis C model animal, which has the full-length DNA of the hepatitis C virus incorporated therein and can express the full-length HCV gene, and a method of generating a hepatitis C model animal carrying the full-length HCV gene, which comprises introducing a vector containing the full-length DNA of hepatitis C virus into an ES cell, and causing the ES cells to undergo ontogenesis in a pseudo-parent.
摘要:
Pharmaceutical compositions for prevention or treatment of diseases caused by interleukin-6 production, comprising an antibody to interleukin-6 receptor (IL-6R antibody). As the IL-6R antibody, an antibody of animals other than the human such as mice, rats, etc., a chimeric antibody between these and a human antibody, a reshaped human antibody, etc. may be used. The pharmaceutical compositions are useful for prevention or treatment of diseases caused by interleukin-6 production such as plasmacytosis, anti-IgGl-emia, anemia, nephritis, etc.
