    • The present invention relates to novel LRF-1 and LRF-2 proteins which are related to the CRISP family and a protein called “Neutrophil Inhibitory Factor (NIF)” isolated from the canine hookworm (Ancylostoma caninum) that potently inhibits CD11/CD18-dependent neutrophil function. In particular, isolated nucleic acid molecules are provided encoding the human LRF-1 and LRF-2 proteins. LRF-1 and LRF-2 polypeptides are also provided, as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of LRF-1 or LRF-2 activity. Also provided are diagnostic methods for detecting immune system or other LRF-1- or LRF-2-related disorders and therapeutic methods for treating such disorders.
    • 本发明涉及与CRISP家族相关的新型LRF-1和LRF-2蛋白质,以及从犬钩虫(Ancylostoma caninum)中分离的称为“中性嗜中性粒细胞抑制因子(NIF)”的蛋白质,其有效抑制CD11 / CD18依赖性 中性粒细胞功能。 特别地,提供编码人LRF-1和LRF-2蛋白的分离的核酸分子。 还提供了LRF-1和LRF-2多肽,载体,宿主细胞以及用于制备它们的重组方法也是如此。 本发明还涉及用于鉴定LRF-1或LRF-2活性的激动剂和拮抗剂的筛选方法。 还提供了用于检测免疫系统或其他LRF-1或LRF-2相关疾病的诊断方法以及用于治疗这种疾病的治疗方法。
