The present disclosure relates generally to immunoglobulin-related compositions (e.g., antibodies or antigen binding fragments thereof) that can bind to the CD3 protein. The antibodies of the present technology are useful in methods for detecting and treating cancer or a CD3 -associated pathology in a subject in need thereof.

Disclosed herein are antibodies to SARS-CoV-2 antigens and recombinant nucleic acid sequences that encode the SARS-CoV-2 antibodies. The disclosure also provides a method of preventing and/or treating a SARS-CoV-2 infection or disease or disorder associated with SARS-CoV-2 infection (e.g., COVID-19) in a subject using said compositions and methods.

The present invention relates to a CD24 protein for treating immune-related adverse events (irAEs) associated with cancer immunotherapy. Provided herein is a method of treating, mitigating, minimizing, or preventing immunerelated adverse events (irAEs) associated with a cancer immunotherapy by administering a CD24 protein to a subject in need thereof. The irAE may be diarrhea or another gastrointestinal disorder, pure red cell aplasia, microcytic anemia, lupus, autoimmune nephritism, autoimmune hepatitis, pneumonitis, myocarditis, pericarditis, endocrinopathy, Addison's disease, hypogonadism, Sjogren's syndrome, or type I diabetes. The CCD24 protein may comprise a mature human CD24 or a variant thereof.

The present invention relates to immunogenic immune complexes, related compositions, and related methods.

Provided herein are various embodiments relating to antibodies and fusion proteins and uses thereof. Some of the embodiments include antibodies that bind CCR8. Some of the embodiments include fusion proteins that bind CCR8. Such antibodies and fusion proteins can be used in methods to treat, for example, cancer.

A humanized monoclonal antibody that binds to an advanced glycation end-product-modified protein or peptide on a cell comprises a heavy chain and a light chain. The antibody binds a carboxymethyllysine-modified protein or peptide. A composition comprises a humanized monoclonal antibody that binds to an advanced glycation end-product-modified protein or peptide on a cell and a pharmaceutically acceptable carrier.

Provided is an antibody for treating a cancer, more specifically, an anti-CD43 antibody binding to an extracellular domain of CD43, compositions for treating a cancer or inhibiting a cancer stem cell comprising the antibody as an active ingredient, and methods for screening an agent of inhibiting a cancer stem cell.

The present invention generally relates to antibodies that bind to GPRC5D, including bispecific antigen binding molecules e.g. for activating T cells. In addition, the present invention relates to polynucleotides encoding such antibodies, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the antibodies, and to methods of using them in the treatment of disease.

Antibodies that selectively bind to glycosylated CTLA-4 relative to unglycosylated CTLA-4 are provided. In some aspects, CTLA-4 polypeptides comprising glycosylated amino acid positions are also provided. Methods for making and using such antibodies and polypeptides (e.g., for the treatment of cancer) are also provided.

The invention relates to combination therapy involving two or more antibodies, wherein the Fc regions of the two antibodies have been modified such that hetero-oligomerization between the antibodies is strongly favored over self-oligomerization when antibodies are bound to their corresponding target antigens and such that hetero-oligomerization-independent effector functions of one or both antibodies are eliminated or strongly reduced. The invention also relates to antibodies, compositions, and kits suitable for use in the combination therapy of the invention.
