Abstract: The present disclosure relates to polypeptides, such as fibronectin type III (FN3) domains that can bind CD71, their conjugates, isolated nucleotides encoding the molecules, vectors, host-cells, as well as methods of making and using the same.

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.

Abstract: The present disclosure relates to compositions, such as siRNA molecules and FN3 domains conjugated to the same, as well as methods of making and using the molecules.

Abstract: Methods of treating autoimmune diseases, such as systemic lupus erythematosus using domain antibodies that specifically bind human CD28 are provided. The methods may comprise at least one administration cycle comprising one dose of the domain antibody. The method reduces symptoms of systemic lupus erythematosus compared to placebo.

Abstract: The present disclosure relates to compositions, such as siRNA molecules and FN3 domains conjugated to the same, in combination with enzyme replacement therapies, as well as methods of making and using the same.

Abstract: The present disclosure relates to polypeptides, such as fibronectin type III (FN3) domains that can bind EpCAM, their conjugates, isolated nucleotides encoding the molecules, vectors, host-cells, as well as methods of making and using the molecules.

Abstract: In certain embodiments, the present invention provides a method of treating or preventing lupus (e.g., SLE) in a subject, comprising: (a) identifying the subject as having at least one differentially regulated biomarker selected from CD40, CD40L, CD86, CD80, and PD1; and (b) administering an agent that inhibits the CD40 or CD28 signaling pathway, thereby treating or preventing lupus in the subject. In other embodiments, the present invention provides a method of treating or preventing lupus (e.g., SLE) in a subject, comprising: (a) administering an agent that inhibits the CD40 or CD28 signaling pathway; (b) determining whether the agent neutralizes at least one differentially regulated biomarker selected from CD40, CD40L, CD86, CD80, and PD1; and (c) adjusting the dosing of the agent in the subject, thereby treating or preventing lupus in the subject.

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.
