摘要:
PURPOSE: A conjugate containing soluble fragments of Fc epsilon RI is provided to suppress allergic cytokine secretion and to prevent and treat allergic diseases.CONSTITUTION: A conjugate(NPB301) has soluble fragments of Fc epsilon RI and a material with biocompatibility. The soluble fragment has an amino acid of sequence number 1. The material is human antibody Fc region, polyethylene glycol(PEG), or diacyl glycerol(DAG). The conjugate has the soluble fragments and human antibody Fc region which are conjugated. The soluble fragment is linked with the human antibody Fc region by a peptide linker. The conjugate has an amino acid of sequence number 2. A composition for treating allergic diseases contains the conjugate and one or more pharmaceutically acceptable carriers.COPYRIGHT KIPO 2013본 발명은 면역글로불린 E(IgE)의 Fc 부위에 고친화성을 갖는 수용체인 FcεRI의 수용성(soluble) 단편과 생체 적합성(biocompatibility)을 가지는 물질이 접합된 복합체에 대한 발명으로, 본 발명에 따른 FcεRI의 수용성 단편과 생체 적합성을 가지는 물질이 접합된 복합체는 IgE와 IgE 수용체인 FcεRI의 결합을 저해하여 알레르기성 사이토카인의 분비를 억제시킴으로써 알레르기 질환을 치료 및 예방하는 효과가 있다.
