Disclosed are sequences encoding LIR family members and their deduced amino acid sequences, polypeptides encoded by DNA that hybridizes to defined nucleotide sequences, processes for producing polypeptides of the LIR family, and specific antibodies directed against LIR polypeptides. LIR family members can be used to treat autoimmune diseases and disease states associated with suppressed immune function.

Abstract: The invention is directed to purified and isolated novel ULBP polypeptides, the nucleic acids encoding such polypeptides, processes for production of recombinant forms of such polypeptides, antibodies generated against these polypeptides, fragmented peptides derived from these polypeptides, and the uses of the above. ULBP polypeptide can be found on the surface of human B cell lymphomas. Mammalian forms of ULBP polypeptide in isolated or purified forms are provided. In addition, isolated nucleic acids encoding ULBP polypeptides and expression vectors comprising a cDNA encoding ULBP polypeptides are provided. The ULBP polypeptides can be isolated or synthesized and used to prepare antibodies, and in particular monoclonal antibodies, against the polypeptides. The antibodies, in turn, are useful for detecting the presence of ULBP polypeptides in human cell samples, which can be correlated with the existence of a malignant condition in a patient.

Abstract: Double-stranded cDNA is prepared from polyadenylated RNA extracted from activated human peripheral blood adherent mononuclear cells. The cDNA is inserted within a plasmid vector and then the recombinant plasmid employed to transform an appropriate host. Transformed hosts are identified and grouped into pools. Plasmid DNA prepared from these pools is hybridized with a labeled, synthetic oligonucleotide probe corresponding to a portion of the amino acid sequence of the interleukin 1 protein. Pools of host cells that provide a positive signal to the probe are identified, plated out and then employed in direct bacterial colony hybridization with the same probe, thereby to isolate the particular positive colony. Plasmid DNA is prepared from this colony and characterized by restriction enzyme mapping and sequencing by chain-termination method. The coding region for the IL-1 gene is inserted into a shuttle vector for amplification of the vector followed by expression of functional IL-1.
