  • USES OF MODIFIED HUMAN TUMOR NECROSIS FACTOR RECEPTOR-1 POLYPEPTIDE
    Publication number: 20150119338
    Abstract: The present invention relates to new uses of modified human tumor necrosis factor receptor-1 (TNFRI) polypeptide, and more particularly, to uses thereof for prevention and treatment of dry eye syndrome. The modified TNFRI or modified TNFRI fragment of the present invention has excellent TNF? neutralizing activity, and inhibits TNF? activity on the ocular surface of the patient to suppress inflammation induction effects related to dry eye. Therefore, the modified TNFRI or modified TNFRI fragment of the present invention exhibits remarkable effects in the prevention and treatment of dry eye syndrome, and thus can be very useful in the prevention and treatment of dry eye syndrome.

  • MODIFIED HUMAN THROMBOPOIETIN POLYPEPTIDE FRAGMENT AND MANUFACTURING METHOD THEREOF
    Publication number: 20110294733
    Abstract: The invention concerns human thrombopoietin and in particular modified forms of thrombopoietin (TPO) with improved properties. The improved proteins contain amino acid substitutions at specific positions within the TPO molecule. The invention provides modified TPO molecules, preferably fusion proteins comprising immunoglobulin constant regions and modified human TPO, with improved biological activity concomitant with reduced immunogenic potential in the protein. The improved proteins are intended for therapeutic use in the treatment of diseases in humans.
