The present invention relates to variable domain of a camelid heavy-chain antibodies directed to amyloid β and conjugates thereof. The present invention also relates to the use of these antibody conjugates for treating or diagnosing disorders mediated by amyloid β deposits.

The invention relates generally to antibodies that bind CD71, activatable antibodies that specifically bind to CD71 and methods of making and using these anti-CD71 antibodies and anti-CD71 activatable antibodies in a variety of therapeutic, diagnostic and prophylactic indications.

The present disclosure provides conjugate structures (e.g., polypeptide conjugates) and hydrazinyl-indole compounds used to produce these conjugates. The disclosure also provides methods of production of such conjugates, as well as methods of using the same.

This invention relates to improving delivery of agents to the central nervous system.

Provided is an immune microbubble complex, and a use thereof. An immune-microbubble complex (IMC) according to the presently claimed subject matter includes microbubbles to which an antibody is conjugated, in which the microbubbles have excellent stability and excellent antibody binding strength, and it was confirmed that, when the immune-microbubble complex is treated with high-intensity focused ultrasound (HIFU), an anti-tumor effect is significantly increased and an immune-enhancing effect is exhibited. Therefore, the immune-microbubble complex according to the presently claimed subject matter is expected to increase the efficiency of delivering the conjugated antibody and be used in both diagnosis and treatment of cancer, and exhibit various functions in the field of immunotherapy, including a contrast effect, half-life improvement, improved drug delivery, a lymphocyte concentration effect, cancer immunotherapy and induction of immunotherapy using ultrasound.

The presently described technology relates to the modulation of specific immune responses to create a protective immunity in the treatment of autoimmune diseases and diseases requiring the transplantation of tissue. In particular, the present technology relates to the supression of immune responses in a targeted fashion, by increasing the functional concentration of the CEACAM1 protein in a target tissue to create a localized protective immunity for the treatment of autoimmune diseases and diseases requiring the transplantation of tissue.

The present invention is directed to therapeutic methods using IL-6 antagonists such as antibodies and fragments thereof having binding specificity for IL-6 to improve survivability or quality of life of a patient in need thereof. In preferred embodiments, the anti-IL-6 antibodies will be humanized and/or will be aglycosylated. Also, in preferred embodiments these patients will comprise those exhibiting (or at risk of developing) an elevated serum C-reactive protein level or a reduced serum albumin level prior to treatment. In another preferred embodiment, the patient's Glasgow Prognostic Score will be increased and survivability will preferably be improved.

This disclosure relates to compositions and methods of identifying, isolating, and modulating cells and tissues based on their cellular glycosaminoglycan pattern. In some aspects, provided are anti-GAG motif antibodies or antigen-binding fragments thereof and their use for determining a glycosaminoglycan (GAG) glycotype for a cell. Also provided are methods of isolating cells, identifying cells, detecting a disease or disorder, and/or treating a disease or disorder based on a cellular glycotype.

A example compound according to the present disclosure includes, among other possible things, a nanodot carrier, a moiety, and a linker having first and second functional groups, wherein the first functional group is covalently linked to the nanodot carrier, and the second functional group is covalently linked to the moiety. An example method of making a nanodot carrier is also disclosed.

The present disclosure provides light chain polypeptides that include a C-terminal extension, as well as antibodies and antibody conjugates containing such modified light chain polypeptides, where the C-terminal extension includes one or more cysteine residues. Conjugates that include an antibody of the present disclosure conjugated to an agent via the cysteine residue of the C-terminal amino acid extension are also provided. The present disclosure further provides nucleic acids encoding an antibody light chain polypeptide that includes a C-terminal amino acid extension including a cysteine residue. Pharmaceutical compositions including the antibodies or conjugates of the present disclosure are also provided, as are methods of making and use of the modified anti-bodies and conjugates of the present disclosure.
