Disclosed herein are anti-Seizure Related 6 Homolog Like 2 (SEZ6L2) antibodies and antibody dmg conjugates (ADCs), including compositions and methods of using said antibodies and ADCs.

Provided herein are engineered antibodies that comprise a modified IgA heavy chain constant region, pharmaceutical compositions, and methods of use. The engineered antibodies described herein comprise one or more amino acid substitution or deletion in a constant region of an IgA domain. Further provided herein are methods of treating disorders, including cancer, by administering an engineered IgA antibody described herein.

The present disclosure relates to methods that include the use of a first multi-chain chimeric polypeptide and a second multi-chain chimeric polypeptide for stimulating the NK cells, inducing or increasing proliferation of the NK cells, inducing differentiation of the NK cells, and treating a subject in need thereof using activated NK cells.

Provided herein are engineered antibodies that comprise a modified IgA heavy chain constant region, pharmaceutical compositions, and methods of use. The engineered antibodies described herein comprise one or more amino acid substitution or deletion in a constant region of an IgA domain. Further provided herein are methods of treating disorders, including cancer, by administering an engineered IgA antibody described herein.

Provided herein are heterodimeric proteins (e.g., multispecific antibodies) that exhibit enhanced binding to human Fc gamma receptor IIIA (FcRIIIA) relative to naturally occurring antibodies and retain good manufacturability. Such heterodimeric proteins are particular useful as multispecific binding proteins (e.g., multispecific antibodies). Also provided are pharmaceutical compositions comprising these heterodimeric proteins, nucleic acids encoding these heterodimeric proteins, and expression vectors and host cells for making these heterodimeric proteins.

An objective of the present invention is to provide target tissue-specific antigen-binding molecules, antigen-binding molecules whose antigen-binding activity varies depending on the concentration of an unnatural compound, libraries comprising a plurality of the antigen-binding molecules which are different from one another, pharmaceutical compositions comprising the antigen-binding molecules, methods of screening for the antigen-binding molecules, and methods for producing the antigen-binding molecules. The present inventors created antigen-binding domains whose antigen-binding activity varies depending on the concentration of a small molecule compound or antigen-binding molecules containing an antigen-binding domain, and libraries comprising a plurality of the antigen-binding domains which are different from one another or antigen-binding domains, and demonstrated that the above-noted objective could be achieved by using the libraries. Various diseases originating from target tissues can be treated in a target tissue-specific manner by using the antigen-binding molecules of the present invention.

The invention provides a BASEHIT screening method for identifying proteins that are involved in host-microbe interactions which may function as therapeutic targets.

Disclosed are materials and methods for improved single chain variable fragments.

The invention provides multispecific antibodies and methods of making and using such antibodies.

Provided herein are engineered antibodies that comprise a modified IgA heavy chain constant region, pharmaceutical compositions, and methods of use. The engineered antibodies described herein comprise one or more amino acid substitution or deletion in a constant region of an IgA domain. Further provided herein are methods of treating disorders, including cancer, by administering an engineered IgA antibody described herein.
