Abstract:
본 발명은 산화아연-결합성 펩타이드를 포함하는 단백질과 산화아연 나노입자의 복합체, 의약의 제조를 위한 약물전달체로서의 그의 용도, 상기 복합체를 포함하는 백신 조성물 및 조영제를 제공한다. 산화아연-결합성 펩타이드를 포함하는 단백질은 산화아연 나노입자의 생체 내 활용성을 현저히 개선시키므로, 상기 복합체는 의약의 생체 내 또는 세포 내 전달을 위한 약물전달체로서 사용할 수 있을 뿐만 아니라 생체 또는 세포의 이미징을 위해 사용할 수 있으며, 생물제재를 효과적으로 분리할 수 있는 분리제, 온열치료를 비롯한 치료제, MRI 조영제, 바이오센서에 응용 가능한 비드(bead)의 제조를 위한 용도를 추가로 제공한다.
Abstract:
PURPOSE: A method for screening a therapeutic agent for treating GPCR19(G-protein coupled receptor 19)-related diseases or a method for analyzing efficiency of a GPCR19 agonist is provided to obtain an anti-inflammatory pharmaceutical composition. CONSTITUTION: A method for screening a therapeutic agent for treating GPCR19-related diseases comprises: a step of administering a physiological activity control material to mammals exclusive of humans; a step of administering a GPCR19 agonist test material to the mammals; and a step of analyzing generation of regulatory B cells in the mammals. The test material is determined as a therapeutic agent for treating GPCR19-related diseases when cell production is increased over a control group.
Abstract:
PURPOSE: A fusion antigen and a method for manufacturing a mature dendritic cell vaccine for immunotherapy using the same are provided to improve efficiency. CONSTITUTION: A fusion antigen used in manufacturing dendritic cell vaccine for immunotherapy contains PTD-MUC1 fusion protein containing MUC1(mucin antigen 1) fused to protein transduction domain(PTD) or PTD-Ag85A fusion protein. The fusion antigen is PTD-MUC1-Ag85A or PTD-Ag85A-MUC1. A method for manufacturing the dendritic cell vaccine comprises: a step of preparing immature dendritic cells; and a step of culturing the cells with the fusion antigen for maturing the cells. A pharmaceutical composition for anticancer immunotherapy contains pharmaceutically effective amount of the dendritic cell vaccine and pharmaceutically acceptable carrier.
Abstract:
PURPOSE: A composite of zinc oxide nanoparticles and proteins containing zinc oxide-binding peptides is provided to modify biocompatibility of zinc oxide nanoparticles. CONSTITUTION: A composite of proteins contains zinc oxide-binding peptides and zinc oxide nanoparticles. The zinc oxide-binding peptide has a structure of [(Arg-X_1-X_2-Arg)_m-linker]_n, [(Arg-X_1-X_2-Arg-Lys)_m-linker]_n. In the formula, X_1 is Pro, Ala, Thr, Gln, or Ile; X_2 is His, Ile, Asn, or Arg. The zinc oxide-binding peptide has an amino acid sequence selected from the sequence numbers 1-4.
