We have identified recombinant human cystatins 9 (rCST9) and C (rCSTC) as a combination immunotherapeutic treatment against multidrug-resistant (MDR) New Delhi metallo-β-lactamase-1 (NDM-1)-producing We evaluated the lasting protection of rCST9/rCSTC treatment against MDR NDM-1 pneumonia. Results showed that rCST9/rCSTC treatment modulated endogenous serum biomarkers, cystatins 9 and C and amyloid A, associated with poor patient outcomes and provided prophylactic and long-term protection in a murine model of pneumonia.
我们已鉴定出重组人半胱氨酸蛋白酶抑制剂 9(rCST9)和 C(rCSTC)作为一种联合免疫治疗方法,用于治疗多药耐药(MDR)新德里金属β-内酰胺酶-1(NDM-1)产生的肺炎。我们评估了 rCST9/rCSTC 治疗对 MDR NDM-1 肺炎的持久保护作用。结果表明,rCST9/rCSTC 治疗可调节与患者预后不良相关的内源性血清生物标志物胱抑素 9 和 C 以及淀粉样蛋白 A,并在肺炎的小鼠模型中提供预防和长期保护。
