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 selective catalytic reduction system includes a reducing agent injection module installed in an exhaust pipe through which an exhaust gas is discharged from an engine and configured to inject a reducing agent into the exhaust pipe, a temperature calculator configured to calculate a temperature of the reducing agent injection module using temperature-related information of the reducing agent injection module, and a temperature controller configured to control to increase a reducing agent injection amount of the reducing agent injection module when the calculated temperature.

Abstract: A cooling device for a reducing agent injection module includes a coolant circulation line connected to a module cooling channel for cooling the reducing agent injection module and configured that a coolant circulates therethrough, a closed circuit circulation line respectively connected to a first portion of the coolant circulation line in front of the module cooling channel and to a second portion of the coolant circulation line in rear of the module cooling channel and configured that a portion of the coolant circulation line is selectively used to form a closed circuit, and at least one heat dissipating part provided in the closed circuit to dissipate heat which is transported from the module cooling channel by natural convection of the coolant within the closed circuit.
