摘要:
A treatment method for degenerative brain disorders using a pharmaceutically effective dose of the inhibitor of SUMO1 (small ubiquitin-like modifier 1) and BACE1 (β-secretase) interaction, or the inhibitor of SUMO1 expression or activation is provided. More specifically, it was confirmed that SUMO1 increased BACE1 accumulation and Aβ generation, that is SUMO1 regulated BACE1 accumulation by interacting with BACE1, and BACE1 dileucine motif was involved in SUMO1-mediated BACE1 accumulation. In addition, SUMO1 protein induced autophagy in H4 cells, while SUMO1 depletion reduced LC3-II level. It was further confirmed that SUMO1 and LC3 were co-localized in the cortex of APP transgenic mice. As shown herein, a pharmaceutically effective dose of the inhibitor of SUMO1 and BACE1 interaction or the inhibitor of SUMO1 expression can be effectively used for the treatment of degenerative brain disorders.

The present invention relates to a recombinant antigen derived from Zika virus E protein and use thereof. Specifically, the present invention provides a polynucleotide encoding Zika virus E protein domain III alone or repeatedly three times, a recombinant plasmid vector comprising the polynucleotide, and a DNA vaccine composition that may induce an immune response to Zika virus by expressing a Zika virus antigen protein effectively. In addition, the present invention provides a neutralizing antibody against Zika virus obtained using the polynucleotide and a method for preparing the neutralizing antibody.

The present invention relates to monoclonal antibodies for a spike protein of the Middle East respiratory syndrome coronavirus (MERS-CoV), and a use thereof. Particularly, monoclonal antibodies 77-A5, 77-A6, 90-A3, 90-A9, 90-B2, 90-B7, 90-C4, 90-E5, 90-E6, 90-F1 and 90-F2 according to the present invention have excellent attachment force with respect to a full-length spike protein of MERS-CoV and the S1 domain of the protein, and, of the monoclonal antibodies, the monoclonal antibodies 90-F1, 90-E5, 90-E6, 90-F2, 77-A5 and 77-A6 have excellent attachment force with respect to an RBD antigen of MERS-CoV. Also, the antibodies 77-A5, 77-A6, 90-E5, 90-E6, 90-F1 and 90-F2 exhibit neutralizing capacity with respect to a MERS pseudovirus and MERS-CoV, and the antibodies 90-B2 and 90-B7 exhibit neutralizing capacity only with respect to MERS-CoV. Further, the monoclonal antibodies have a particular monomeric form, and have excellent stability and thus may be useful for treating or diagnosing MERS.

The present invention relates to a GCP II (glutamate carboxypeptidase II) mutant (K699S) having the activity of inhibiting glutamate production and the activity of cleavaging β-amyloid, and to a pharmaceutical composition for the prevention and treatment of a disease selected from the group consisting of amyloidosis, Alzheimer's disease, Down syndrome accompanying Alzheimer's disease, stroke, dementia, Huntington's disease, Pick's disease, and Creutzfeldt-Jakob disease comprising the GCP II mutant (K699S) as an active ingredient. The GCP II (glutamate carboxypeptidase II) mutant (K699S) demonstrates not only excellent Aβ cleavage activity compared with the wild type GCP II but also excellent activity of inhibiting glutamate production, unlike the wild type GCP II, so that the mutant has been confirmed to have higher effect and stability than the wild type, suggesting that the GCP II mutant can be effectively used for the prevention or treatment of neurodegenerative diseases.

The present inventors screened peptides having a specific sequence specifically binding to amyloid-beta antibody and accordingly confirmed that Aβ22(pE)-42 peptide showed higher reactivity to amyloid-beta antibody in serum of Alzheimer's disease patients. Therefore, the said Aβ22(pE)-42 peptide can be used as an active ingredient for the kit for diagnosing dementia and thus it can be said that the peptide can be effectively used for the diagnosis of dementia whose early diagnosis is hardly possible.
