    • The disclosure relates to a monovalent polypeptide domain which specifically binds CD28, as well as to an antagonist of CD28, where the antagonist comprises a monovalent polypeptide domain which specifically binds CD28. This disclosure encompasses monovalent polypeptide domains comprising an antibody single variable domain that monovalently binds CD28. An antibody single variable domain that is monovalent for binding of CD28 can inhibit CD28 activity. In one aspect, a monovalent anti-CD28 antibody single variable domain consists of or comprises an antibody single variable domain that specifically binds and antagonizes the activity of CD28, in an aspect, without substantially agonizing CD28 activity. In another aspect, the monovalent anti-CD28 antibody single variable domain is a human antibody single variable domain. 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 monovalent anti-CD28 antibody single variable domain to the individual.
    • 本公开涉及特异性结合CD28的单价多肽结构域以及CD28拮抗剂,其中拮抗剂包含特异性结合CD28的单价多肽结构域。 本公开内容涵盖包含单价结合CD28的抗体单可变结构域的单价多肽结构域。 用于结合CD28的单价抗体单可变区可抑制CD28活性。 在一个方面,单价抗CD28抗体单可变结构域由一个方面组成或包含特异性结合和拮抗CD28的活性的抗体单可变结构域,而不具有实质上激动的CD28活性。 另一方面,单价抗CD28抗体单可变结构域是人抗体单可变结构域。 本公开还包括在个体中拮抗CD80和/或CD86相互作用的方法以及涉及CD80和/或CD86与CD28相互作用的疾病或病症的方法,涉及向单克隆抗CD28抗体单可变结构域施用的方法 个人。

    • 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。 针对CD40L结合的单价抗体多肽可以抑制CD40L活性,同时避免可能与能够进行CD40L二价或多价结合的抗体发生的不良反应。 一方面,单价抗CD40L抗体多肽由特异性结合和拮抗CD40L的活性的单个免疫球蛋白可变区组成或包含,优选不具有实质上激动的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相互作用的拮抗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,涉及向个体施用单价抗CD40L抗体多肽的方法。
