The present invention relates, in part, to agents that bind CD8 and their use as therapeutic and diagnostic agents. The present invention further relates to pharmaceutical compositions comprising the CD8 binding agents and their use in the treatment of various diseases, including, for example, cancers.

Antibodies, including single-domain antibodies, that bind to SARS-CoV2 virus and methods of treatment using single-do-main antibodies that bind to SARS-CoV2 virus are provided.

The present invention relates to a low-molecular antibody composed of D-amino acids and achiral glycine, a method for producing the same, and a method for screening the low-molecular antibody using a mirror-image target protein corresponding to a target protein and an antibody library.

The present invention relates to compositions and methods for the prevention or the treatment of lung cancer, wherein the compositions comprise an antibody binding to progastrin and the methods comprise the use of an antibody binding to progastrin.

The present invention relates to the field of virology, more specifically to the field of zoonotic Coronaviruses. Specifically, the invention provides for binding agents specific for the spike protein receptor binding domain (RBD) of the SARS-Corona virus, more specifically for an epitope of the RBD present in a broad range of Sarbecoviruses and mutants thereof, even more specifically present in SARS-Cov and SARS-CoV-2 viruses. More specifically, the invention relates to compositions comprising antibodies capable of specifically binding and neutralizing SARS-Corona viruses. More specifically the invention relates to compositions comprising single domain antibodies, or specifically VHHs, and compositions comprising multivalent binding agents comprising IgG Fc fusions thereof, specifically VHH-Fc fusions thereof, even more specifically comprising heavy chain only VHH72-S56A-IgG1-Fc fusions, or compositions comprising any humanized form of any one thereof, and are capable of specifically binding and neutralizing SARS-Corona viruses, specifically SARS-Cov-2 virus. The compositions are useful in the diagnosis of Sarbecoviruses, and specifically SARS-CoV-2 virus, and in prophylactic and/or therapeutic treatment of a condition resulting from infections with Sarbecoviruses, specifically SARS-Corona or SARS-CoV-2 virus, or mutants thereof.

The present disclosure relates extracellular vesicles, e.g., exosomes, comprising an antigen-binding moeity, e.g., a single-domain antigen-binding moeity, e.g., a vNAR, a VHH, or a fragment thereof, that specifically binds transferrin receptor, and methods of making and using the same.

The present invention concerns modified recombinant J-chain polypeptides, binding molecules, such as antibodies comprising the same, and their uses.

This disclosure relates to anti-coronavirus (e.g., SARS-CoV-2) antibodies or antigen-binding fragments and uses thereof.

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 present invention relates to dimers comprising a first polypeptide and a second polypeptide, wherein each of said first and second polypeptide comprises at least one immunoglobulin single variable domain (ISVD) and a C-terminal extension comprising a cysteine moiety (preferably at the C-terminus), wherein said first polypeptide and said second polypeptide are covalently linked via a disulfide bond between the cysteine moiety of said first polypeptide and the cysteine moiety of said second polypeptide, in which the dimer outperformed the benchmark constructs, e.g. cognate multivalent and multispecific constructs, in various assays. The present invention provides methods for making the dimers of the invention.
