    • The invention relates to antibody polypeptides that monovalently bind CD40L. Antibody polypeptides that are monovalent for binding of CD40L can inhibit CD40L activity while avoiding potential undesirable effects that can occur with antibodies capable of divalent or multivalent binding of CD40L. In one aspect, a monovalent anti-CD40L antibody polypeptide consists of or comprises a single immunoglobulin variable domain that specifically binds and antagonizes the activity of CD40L, preferably without substantially agonizing CD40 and/or CD40L activity. In another aspect, the monovalent anti-CD40L antibody polypeptide is a human antibody polypeptide. The invention further encompasses methods of antagonizing CD40/CD40L interactions in an individual and methods of treating diseases or disorders involving CD40/CD40L interactions, the methods involving administering a monovalent anti-CD40L antibody polypeptide to the individual.
    • 本发明涉及单价结合CD40L的抗体多肽。 单价用于结合CD40L的抗体多肽可以抑制CD40L活性,同时避免可以用能够与CD40L二价或多价结合的抗体发生的潜在的不良影响。 一方面,单价抗CD40L抗体多肽由单个免疫球蛋白可变结构域组成或包含单个免疫球蛋白可变结构域,其特异性结合并拮抗CD40L的活性,优选基本上不激动CD40和/或CD40L活性。 另一方面,单价抗CD40L抗体多肽是人抗体多肽。 本发明还包括拮抗个体中CD40 / CD40L相互作用的方法以及治疗涉及CD40 / CD40L相互作用的疾病或病症的方法,所述方法包括向个体施用单价抗CD40L抗体多肽。
