Abstract: The present disclosure relates to an isolated anti-FcRN antibody, which is an antibody binding to FcRN (stands for neonatal Fc receptor, also called FcRP, FcRB or Brambell receptor) that is a receptor with a high affinity for IgG or a fragment thereof, a method of preparing thereof, a composition for treating autoimmune disease, which comprises the antibody, and a method of treating and diagnosing autoimmunre diseases using the antibody. The FcRn-specific antibody according to the present disclosure binds to FcRn non-competitively with IgG to reduce serum pathogenic auto-antibody levels, and thus can be used for the treatment of autoimmune diseases.

Abstract: A thermoplastic resin composition includes (A) a rubber reinforced aromatic vinyl resin; (B) a recycled polyester resin; (C) a vinyl copolymer including an epoxy group; and (D) a phosphorus flame retardant. The thermoplastic resin composition can be flame retardant and environmentally friendly and can have improved falling ball impact strength, flowability (fluidity), chemical resistance, thermal stability and/or processability.
