The present disclosure provides antibody sequences found in antibodies that bind to human CD25, in particular an anti CD25-a-674 antibody which do not block the binding of CD25 to IL-2 or IL-2 signalling. The claimed antibody binds to the epitopes: QCVQGYRA and RWTQPQLICTG on CD25 Antibodies and antigen-binding portions thereof including such sequences can be used in pharmaceutical compositions and methods of treatment, in particular for treating cancer.

The invention is in the field of medicine and relates to immunology, and relates in particular to human Vγ9Vδ2 T cell receptor bindingimmunoglobulin molecules. Human Vγ9Vδ2 T cell receptor binding immunoglobulin molecules are in particular for use in medical treatment and/or useful in assays with human Vγ9Vδ2 T cells, wherein human Vγ9Vδ2 T cells may be modulated.

The invention relates to antibody therapies in veterinary medicine, in particular full-length antibodies and antibody fragments, by providing methods to improve the production of heterodimeric antibodies for veterinary medicine as well as providing related products and uses.

The present invention relates to monoclonal anti-Sortilin antibodies which have been found useful correcting a deficient level progranulin (PGRN). In particular, these antibodies can be used in the treatment of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS).

Provided are compositions for increasing the half-life of a polypeptide or polypeptides in a canine and methods of their use. The compositions involve variant canine IgG Fc regions.

The present disclosure provides humanized antibodies, including antibodies comprising an ultralong CDR3 and uses thereof.

The present invention provides a novel use and methods comprising antibodies, or antigen-binding fragments thereof, which bind to a CCR7 receptor for use as a novel combination therapy with a BTK inhibitor and/or a Bcl-2 inhibitor in treatment of hyperproliferative blood malignancies, preferably in B-cell lymphomas, such as CLL. The combination can be used as first line, or in naïve patients not treated before with a BTK inhibitor and/or Bcl-2 inhibitor, or in patients with a BTK-inhibitor and/or Bcl-2-inhibitor refractory/relapsed disease. The antibodies and antigen-binding fragments are capable of selectively depleting ex vivo or in vitro malignant cells expressing CCR7 and are capable of impairing/blocking migration of said tumor cells towards CCR7 ligands. These effects are not related to previous or contemporary treatments with a BTK inhibitor and/or a Bcl-2 inhibitor. Similarly, the efficacy of the antibodies is not affected in patients that have relapsed/refractory disease. The use of said antibodies as a monotherapy or as a combination with a BTK inhibitor and/or a Bcl-2 inhibitor for depleting, killing and impairing/blocking migration and activation of tumor cells expressing CCR7 cells is disclosed, thus providing an alternative therapy treating hyperproliferative blood cancers.

Provided are chimeric cytokine modified antibodies containing an ultralong CDR3, such as based on a bovine antibody sequence or a humanized sequence thereof, in which a portion of the CDR3 of the heavy chain is replaced by an interleukin (IL-15) or IL-2, and related antibodies. Among provided antibodies are chimeric IL-15 cytokine modified antibody molecules that are further linked or complexed with an extracellular portion of the IL15Rα, such as the IL15Rα sushi domain. Also provided are methods of making and using the chimeric cytokine modified antibodies.

The present invention relates to the fields of molecular medicine and targeted delivery of therapeutic or diagnostic agents to cells outside the vascular system and into the parenchymal tissue of organs within the body. More specifically, the present invention relates to improved TfR-binding moieties based on shark VNARs capable of crossing the blood brain barrier (BBB) and capable of carrying and releasing cargo specifically targeted to the parenchymal tissue of the brain.

Transgenic mammals that express bovine-based immunoglobulins are described herein, including transgenic rodents that express bovine-based immunoglobulins for the development of bovine therapeutic antibodies.
