Abstract

Host-directed therapies that augment host immune effector mechanisms may serve as important adjunctive therapies for tuberculosis treatment. We evaluated the activity of denileukin diftitox in an acute mouse model of tuberculosis (TB) infection and analyzed the cellular composition and bacterial burden in lungs and spleens. These in vivo studies show that denileukin diftitox potentiates standard TB treatment in the mouse model, an effect which may be due to depletion of T-regulatory and myeloid-derived suppressor cells during TB infection. Our results indicate that denileukin diftitox and other suppressor cell-depleting therapies may be useful adjunctive, host-directed therapies for TB.

摘要

增强宿主免疫效应机制的宿主导向疗法可能成为结核病治疗的重要辅助疗法。我们在急性小鼠结核病感染模型中评估了地尼白介素(denileukin diftitox)的活性,并分析了肺和脾中的细胞组成及细菌负荷。这些体内研究表明,地尼白介素在小鼠模型中可增强标准结核病治疗效果,这一效应可能归因于结核病感染期间调节性T细胞和髓源性抑制细胞的耗竭。我们的结果表明,地尼白介素及其他抑制细胞耗竭疗法可能是有用的辅助性宿主导向结核病治疗方法。
