The present invention relates to a receptor-binding domain of an IgE-dependent histamine releasing factor (HRF), and a use thereof and, more specifically, ascertains, as an HRF framework region, an FL domain and an H2 domain which bind to a receptor of an HRF existing in a cell membrane, ascertains the C-terminus of the HRF, and ascertains that a material binding thereto inhibits IL-8 secretion, thereby determining that the FL and H2 domains and the C-terminus can be utilized in: the development of a therapeutic agent for and prevention of HRF-related diseases including malaria and inflammatory diseases such as asthma, bronchitis, chronic obstructive pulmonary disease, bronchiectasis, rhinitis, atopic dermatitis, hives, hay fever, conjunctivitis, anaphylactic allergic diseases, pneumonia, arthritis, nephritis, psoriasis, dermatitis, Crohn's disease, enteritis, gingivitis, arteriosclerosis, coronary arteritis, hepatitis, Behcet's disease, bladder cancer, prostatitis, pyelonephritis, glomerulonephritis, osteomyelitis, thyroiditis, uveitis, abdominal cavity inflammation, meningitis, pulmonary fibrosis and rheumatoid arthritis； and a method for screening for the HRF-related diseases.
