Research Abstract

ロイコトリエンB4(LTB4)は、アラキドン酸に由来する 生理活性脂質であり、様々な炎症性疾患における重要な役割が示唆されてきた。LTB4がアレルギー性の気道反応に必須であるかどうかを直接証明するために、LTB4を全く産生しないLTA4 hydrolase knock out(LTA4HKO) マウスを用いて喘息モデルを作成し、コントロールの野生型マウスとの比較検討をおこなった。野生型マウスに比べ、LTA4HKOマウスは有意に低い気道過敏性を示し、肺内の好酸球の数、杯細胞の過形成の程度も低下していたことより、LTB4はアレルギー性気道反応においても反応惹起に必須であることが示唆された
