摘要:
A peptide according to the present invention can perform a function identical or similar to the function of natural CTLA-4 and has an excellent degree of skin penetration due to a small size. The peptide according to the present invention effectively binds to antigen presenting cell surface proteins (CD80 and CD86) to inhibit activity of T cells and thus is capable of inhibiting the expression of inflammatory cytokines (for example, IL-2 and IFN-³). As a result, a composition comprising the peptide according to the present invention exhibits excellent effects in terms of preventing, treating, or improving Th1-mediated immune diseases. Therefore, the superior activity and stability of the peptide according to the present invention can be useful when applied to medicine, quasi-drugs, and cosmetics.

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 autoimmune 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.

摘要:
Methods of treating a tumor in a subject and methods of determining a treatment regimen for a subject with a tumor are provided herein. In exemplary aspects, the methods comprise measuring the level of expression of immunoglobulin, FCGR2B, a gene listed in Table 4, or a combination thereof. In exemplary aspects, the subject is a subject from which a sample was obtained, wherein the level of immunoglobulin, FCGR2B, a gene listed in Table 4, or a combination thereof, has been measured from the sample. Related kits, computer readable-storage media, systems, and methods implemented by a processor in a computer are further provided.
摘要:
The specification describes an antibody capture process comprising (i) obtaining a biological sample comprising antibodies, (ii) contacting the biological sample with recombinant pIgR or a dIgA-binding variant, wherein the pIgR or variant binds dIgA and forms a pIgR-dIgA complex. The process may further comprise (iii) directly or indirectly assessing the level of the pIgR-dIgA complex or the level of a complex between pIgR-dIgA and an antigen of interest. There is also an antibody capture process for determining gut wall integrity in a test subject, wherein the level or ratio of SIgA to dIgA is compared to a corresponding level or ratio from a control subject. The specification provides kits embodying the process and recombinant pIgR when used for, or for use, in capturing or detecting dIgA and/or IgM.
摘要:
The present invention relates to a method of preparing a genetic package displaying oligomers of modular antibody domains binding to a target and to a scaffold ligand as well as to vectors and libraries of genetic packages produced thereby. The invention further relates to methods of selecting suitable linker sequences for use in such oligomer display.
摘要:
The invention relates a method of quantifying CD64 and CD 163 expression in leukocytes and, specifically to a kit for use with a flow cytometer including a suspension of quantitative fluorescent microbead standards, fluorescent labeled antibodies directed to CD64 and CD 163, and analytical software. The software is used to take information on the microbead suspension and fluorescent labeled antibodies from a flow cytometer and analyse data, smooth curves, calculate new parameters, provide quality control measures and notify of expiration of the assay system.
