Defensin 5 (human)别名Defensin HD 5, HD 5, Human α-defensin 5, α-Defensin 5 (human),是肠道微生物区体内稳态的关键调剂剂。Defensin 5 (human)由小肠内的帕内特细胞(Paneth cells)释放,对细菌,真菌和病毒显示出抗生活性。肠内粘膜Defensin 5 (human)释放的减少或者消失与肠道病原体过敏,微生物组成的改变和肠内免疫体内稳态的紊乱有关系。作为生物标记物,Defensin 5 (human)可能被用来区分溃疡性结肠炎(低水平Defensin 5 (human))还是克罗恩结肠炎(高水平Defensin 5 (human))。
