Specifically, the present invention provides transgenic mice comprising disruptions in PRO218, PRO228, PRO271, PRO273, PRO295, PRO302, PRO305, PRO326, PRO386, PRO655, PRO162, PRO788, PRO792, PRO940, PRO941, PRO1004, PRO1012, PRO 1016, PRO474, PRO5238, PRO1069, PRO1111, PRO1113, PRO1130, PRO1195, PRO1271, PRO1865, PRO1879, PRO3446, PRO3543, PRO4329, PRO4352, PRO5733, PRO9859, PRO9864, PRO9904, PRO9907, PRO10013, PRO90948, PRO28694, PRO16089, PRO19563, PRO19675, PRO20084, PRO21434, PRO50332, PRO38465 or PRO346 genes.

Abstract: The present invention relates to transgenic animals, as well as compositions and methods relating to the characterization of gene function. Specifically, the present invention provides transgenic mice comprising disruptions in PRO256, PRO34421, PRO334, PRO770, PRO983, PRO1009, PRO1107, PRO1158, PRO1250, PRO1317, PRO4334, PRO4395, PRO49192, PRO9799, PRO21175, PRO19837, PRO21331, PRO23949, PRO697 or PRO1480 genes. Such in vivo studies and characterizations may provide valuable identification and discovery of therapeutics and/or treatments useful in the prevention, amelioration or correction of diseases or dysfunctions associated with gene disruptions such as neurological disorders; cardiovascular, endothelial or angiogenic disorders; eye abnormalities; immunological disorders; oncological disorders; bone metabolic abnormalities or disorders; lipid metabolic disorders; or developmental abnormalities.

Abstract: Methods of treating lupus, including systemic lupus erythematosus, cutaneous lupus erythmetosus, and lupus nephritis, are provided. The methods involve administration of a combination of a non-depleting CD4 antibody and another compound used clinically or experimentally to treat lupus. Methods of treating lupus nephritis by administration of a non-depleting CD4 antibody that results in an improvement in renal function and/or a reduction in proteinuria or active urinary sediment are also provided. Methods of treating lupus or decreasing autoantibody titer by administration of a non-depleting CD4 antibody are also provided. Methods of treating multiple sclerosis by administration of a non-depleting CD4 antibody, optionally in combination with another compound used clinically or experimentally to treat MS, are described. Methods of treating transplant recipients and subjects with rheumatoid arthritis, asthma, psoriasis, Crohn's disease, ulcerative colitis, and Sjogren's syndrome are also provided.

Abstract: Chimeric proteins and DNA encoding chimeric proteins are provided, where the chimeric proteins are characterized by an extracellular domain capable of binding to a ligand in a non-MHC restricted manner, a transmembrane domain and a cytoplasmic domain capable of activating a signaling pathway. The extracellular domain and cytoplasmic domain are not naturally found together. Binding of ligand to the extracellular domain results in transduction of a signal and activation of a signaling pathway in the cell, whereby the cell may be induced to carry out various functions relating to the signalling pathway. A wide variety of extracellular domains may be employed as receptors, where such domains may be naturally occurring or synthetic. The chimeric DNA may be used to modify lymphocytes as well as hematopoietic stem cells as precursors to a number of important cell types.
