PROBLEM TO BE SOLVED: To provide a composition and a method for treating an inflammation and an autoimmune disease.SOLUTION: Provided is a composition that contains a soluble B7-H4(sH4) antagonist in an effective amount sufficient to reduce, inhibit or alleviate an inflammatory response in an individual. Also, provided is a method for treatment or prevention of an inflammatory disorder and an autoimmune disease or disorder. It is known that a soluble H4 obstructs the B7-H4 activity that includes an activity of B7-H4 as an inhibitor of T-cell immunity. An interference of an sH4 biological activity is an effective method for recovering the B7-H4 activity. Therefore, it can be an effective method for treatment of the inflammatory disease or disorder that includes the autoimmune disease or disorder.【課題】炎症および自己免疫疾患を治療するための組成物および方法の提供。【解決手段】個体における炎症反応を減少、阻害、又は軽減するために有効な量の可溶性B7-H4(sH4)アンタゴニストを含む組成物と、炎症性障害及び自己免疫性疾患又は障害の治療又は予防の方法が、提供される。可溶性H4は、T細胞性免疫の阻害剤としてのB7-H4の活性を含む、B7-H4活性を妨げることが分かっている。したがって、sH4生物活性の干渉は、B7-H4活性を回復する有効な方法であり、したがって自己免疫性疾患又は障害を含む炎症性疾患又は障害の治療に有効な方法を提供する。【選択図】図8a
