Abstract: Provided herein are polypeptides that are capable of crossing the cellular membrane and entering into the intracellular environment, which polypeptides are suitable for use in prophylactic, therapeutic or diagnostic applications as well as in screening and detection. Nucleic acids encoding such polypeptides; methods for preparing such polypeptides, host cells expressing or capable of expressing such polypeptides, compositions, and in particular pharmaceutical compositions, that comprise such polypeptides, in particular for prophylactic, therapeutic or diagnostic purposes are also provided.

Abstract: The present invention relates to the diagnosis of autoimmune disorders, more specifically to the diagnosis of rheumatoid disorders, chronic autoimmune arthritis and even more specifically to the diagnosis of rheumatoid arthritis. A biomarker panel is provided which can be used to detect if a subject has rheumatoid arthritis. Also described are methods of identification of such biomarkers.

Abstract: The application provides Alphabodies that specifically bind to IL-23, as well as to polypeptides that comprise or essentially consist of such Alphabodies. Also provided herein are nucleic acids encoding such Alphabodies; to methods for preparing such Alphabodies and polypeptides; and in particular to pharmaceutical compositions, that comprise such Alphabodies, polypeptides, nucleic acids and/or host cells.

Abstract: The invention relates to a modified phage display that allows the specific detection of citrullinated proteins. More specifically, the invention relates to a method for citrullinating proteins displayed by phage, without losing phage infectivity, and the detection of those proteins by biopanning. In a preferred embodiment, the phage is a T7 phage.
