  • Publication number: 20220073636
    Abstract: Antibody polypeptides that specifically bind human CD40L are provided. The antibody polypeptides do not activate platelets. The antibody polypeptides are useful in the treatment of diseases involving CD40L activation, such as graft-related diseases and autoimmune diseases. The antibody polypeptides may be domain antibodies (dAbs) comprising a single VH or VK domain. The half-life of the antibody polypeptides may be increased by modifying the antibody polypeptides to be dual specific reagents that can also bind human serum albumin (HSA) or another antigen.

  • Publication number: 20210047414
    Abstract: Disclosed are domain antibodies that monovalently bind CD28. Domain antibodies that are monovalent for binding of CD28 can inhibit CD28 activity. In one aspect, a domain antibody consists of or comprises a single immunoglobulin variable domain that specifically binds and antagonizes the activity of CD28, in an aspect, without substantially agonizing CD28 activity. In another aspect, the domain antibody is a human domain antibody. The disclosure further encompasses methods of antagonizing CD80 and/or CD86 interactions with CD28 in an individual and methods of treating diseases or disorders involving CD80 and/or CD86 interactions with CD28, the methods involving administering a domain antibody to the individual.
