This invention relates to inhibition of the complement signaling using an anti-C5 antibody. Specifically, the invention relates to methods of treating a complement-mediated disease or complement-mediated disorder in an individual by contacting the individual with an anti-C5 antibody.

A novel human bladder cancer marker AG-CD71 and a monoclonal antibody ABC71 for preventing AG-CD71 are provided. The human bladder cancer marker AG-CD71 is an abnormal glycosylated transferrin receptor TFRC; the abnormal glycosylated transferrin receptor TFRC refers to the TFRC carrying a saccharide structure Fucal-4(GlcNAcbl-3)[6OSO3]GlcNAc as an epitope. Also provided is an antibody for the human bladder cancer marker AG-CD71; the antibody is the monoclonal antibody ABC71 specific for the human bladder cancer AG-CD71; the monoclonal antibody is secreted from the hybridoma cell strain the preservation number of which is CGMCC No. 14312.

The invention relates to anti-EGF like domain multiple 6 antibody (anti-EGFL6 antibody) and cancer detection (or diagnosis) and treatment using the anti-EGFL6 antibody. The present invention creates anti-EGFL6 antibodies, particularly, a single-chain antibody fragments (scFv) and humanized antibody, which have ability in binding to EGFL6 and in inhibiting angiogenesis and cancer cell growth.

The presently disclosed subject matter relates to a composition and method of using the composition for oral delivery of a bioactive agent to a subject. More particularly, the presently disclosed subject matter relates to a composition comprising an effective amount of at least one bioactive agent layered over a substrate and a method of reducing zoonotic infectious disease by administering the composition to a subject. The presently disclosed subject matter further relates to a method of preparing the composition.

The present invention relates to antibodies having specificity to HER4 and uses thereof, which are able to induce biased 4ICD routing/signaling. The inventors have isolated by antibody phage display three fully human anti-HER4 single-chain variable antibody fragment (scFv), selected on human HER4 extracellular domain, referred as C6 mAb, D5 mAb and F4 mAb and one fully human anti-HER4 scFv named H2 mAb, selected on NRG 1β1-stimulated EGFR/HER4 JMaCYT1-transfected NIH3T3 cells. In particular, the present invention relates to an isolated anti-HER4 antibody, wherein said antibody binds to an epitope of the HER4 protein.

Methods and compositions for identifying tumor antigens of human lymphocytes, and for treating subjects having cancer, are provided herein.

Methods of decreasing shedding of CD28, decreasing soluble CD28 levels, treating cancer and improving immunotherapies comprising inhibiting matrix metalloproteases are provided. Methods of producing agents for performance of the methods of the invention are also provided.

Nucleic acids encoding fusion proteins that contain an unwanted antigen and a leader sequence for cell secretion are described. Also described are expression cassettes, vectors, cells, and cell lines containing the nucleic acids, as well as methods of using the nucleic acids to treat autoimmune, allergic and other diseases and disorders, such as multiple sclerosis.

Provided are a tumor immune enhancer, a pharmaceutical composition thereof, and a preparation method therefor. The enhancer comprises one or more polypeptides using sequences shown in SEQ ID NOs.: 1-9 as core structures, and can be used for preparing tumor vaccines.
