Abstract: Disclosed are compositions and methods related to variable lymphocyte receptors (VLRs). More particularly, disclosed are a variety of antigen specific polypeptides, including soluble, monoclonal, and multivalent forms, as well as methods of using the polypeptides, antibodies that bind the antigen specific polypeptides, and nucleic acids, vectors and expression systems that encode the polypeptides. Antigen specific polypeptides that selectively bind pathogens, like anthrax, and carbohydrates, like blood group determinants, are specifically disclosed.

Abstract: The invention relates to members of the Fc receptor homolog (FcRH) subfamily, as well as fragments and variants thereof. Each FcRH is a Type I transmembrane receptor, preferably, comprises an extracellular region, a transmembrane region, and a cytoplasmic region. The cytoplasmic region preferably comprises one or more immunoreceptor tyrosine-based inhibitory or activation motifs (“ITIMs” or “ITAMs). The invention provides polypeptides, nucleic acids, vectors, expression systems, and antibodies and antibody fragments related to the FcRHs as well as uses thereof. Such uses include uses in the diagnosis and treatment of a malignancy of hematopoietic cell lineage or an inflammatory or autoimmune disease in a subject and in the modulation of a humoral immune response in a subject.

Abstract: Provided herein are antibodies having the same epitope specificity as an antibody produced by the hybridoma cell line deposited with the American Type Culture Collection as hybridoma 4-2A6, 1-5A3, or 1-3B4. Further provided herein are methods of identifying and selecting cells that express FcRH1 or FcRH4. Methods of diagnosing and treating a subject with a malignancy of a hematopoietic cell lineage or an autoimmune disease and methods of modulating a humoral immune response in a subject are also provided herein. Further provided herein are polypeptides comprising one or more complementary determining regions of the disclosed antibodies and nucleic acids that encode the disclosed polypeptides.
