    • The present invention relates to isolated and/or recombinant nucleic acids which encode a mammalian (e.g., human) receptor protein designated C—C Chemokine Receptor 3 (CKR-3) or Eos L2, and to proteins or polypeptides, referred to herein as isolated, recombinant mammalian CKR-3 receptors. The invention further relates to recombinant nucleic acid constructs, comprising a nucleic acid which encodes a receptor protein of the present invention or a portion thereof; to host cells comprising such constructs, useful for the production of recombinant CKR-3 receptors or polypeptides; and to antibodies reactive with the receptors, which are useful in research and diagnostic applications. Also provided are methods of use of the nucleic acids, proteins, and host cells to identify ligands, inhibitors (e.g., antagonists) or promoters (agonists) of receptor function. Administration of a compound which inhibits or promotes receptor function to an individual in need of therapy provides a new approach to selective modulation of leukocyte function, which is useful in a variety of inflammatory and autoimmune diseases, or in the treatment of infections. As a major leukocyte chemokine receptor present in leukocytes such as eosinophils and lymphocytes, the receptor provides a key target for drug screening and design.
    • 本发明涉及编码称为CC趋化因子受体3(CKR-3)或Eos L2的哺乳动物(例如,人)受体蛋白以及本文称为分离的重组体的蛋白质或多肽的分离和/或重组核酸 哺乳动物CKR-3受体。 本发明还涉及重组核酸构建体,其包含编码本发明的受体蛋白或其部分的核酸; 包含可用于产生重组CKR-3受体或多肽的包含此类构建体的宿主细胞; 以及与受体反应的抗体,其可用于研究和诊断应用。 还提供了使用核酸,蛋白质和宿主细胞来鉴定受体功能的配体,抑制剂(例如拮抗剂)或启动子(激动剂)的方法。 给予需要治疗的个体抑制或促进受体功能的化合物的施用提供了选择性调节白细胞功能的新方法,其可用于多种炎性和自身免疫疾病或用于治疗感染。 作为白细胞如嗜酸性粒细胞和淋巴细胞中存在的主要白细胞趋化因子受体,该受体是药物筛选和设计的关键目标。

    • The present invention relates to proteins or polypeptides, referred to herein as isolated and/or recombinant mammalian (e.g., human) IP-10/Mig receptor proteins designated CXC Chemokine Receptor 3 (CXCR3) and variants thereof, including those characterized by selective binding of one or more chemokines (e.g., IP-10 and/or Mig), and/or the ability to induce a cellular response (e.g., chemotaxis, exocytosis). Antibodies reactive with CXCR3 receptors can be produced using the proteins or variants thereof or host cells comprising same as immunogen. Another aspect of the invention relates to isolated and/or recombinant nucleic acids encoding a mammalian (e.g., human) CXCR3 protein and variants thereof, including antisense nucleic acid, recombinant nucleic acid constructs, such as plasmids or retroviral vectors, comprising a nucleic acid which encodes a protein of the present invention or variant thereof, and to host cells comprising a nucleic acid or construct, useful in the production of recombinant proteins. Also encompassed are methods of identifying ligands, and inhibitors (e.g., antagonists) or promoters (e.g., agonists) of receptor function, including methods in which host cells comprising a nucleic acid encoding a CXCR3 or variant thereof are used in an assay to identify and assess the efficacy of ligands, inhibitors or promoters. Inhibitors and promoters of receptor function can be used to modulate receptor activity, permitting selective inhibition of lymphocyte function, particularly of effector cells such as activated T lymphocytes and NK cells for therapeutic purposes.
