甲状腺类激素类激素 (PTHLH) 和其PTHrP1-34,由支气管上皮细胞分泌,通过激活纤维细胞,驱动异常性肺纤维化 (IPF) 的进展. 针对这种途径为IPF提供了一个潜在的治疗策略.
科学领域:
- 肺部医学 肺部医学
- 细胞生物学 细胞生物学
- 分子生物学分子生物学
背景情况:
- 异形性肺纤维化 (IPF) 的发病过程涉及肺细胞之间通过膜信号传递的交叉通话.
- 来自支气管上皮细胞的可溶媒体在纤维细胞激活和IPF中的作用尚未研究.
研究的目的:
- 研究支气管上皮细胞衍生媒介在激活纤维细胞和促进肺纤维化中的作用.
- 确定IPF的新型治疗点.
主要方法:
- 重新分析来自人类和小鼠肺组织的大量和单细胞RNA测序数据.
- 对甲状腺激素相关蛋白 (PTHrP) 和其PTHrP1-34水平的测量.
- 在体外基于细胞的测试和体内动物模型 (白胺诱导的肺纤维化).
- 使用中和抗体,和基因沉默以向PTHrP1-34/副甲状腺激素1受体轴的临床前评估.
主要成果:
- 甲状腺类激素类激素 (PTHLH) 和PTHrP在IPF肺组织和支气管上皮质中显著上调.
- PTHrP1-34在纤维化肺部升高,并激活纤维细胞,促进细胞外基质的产生.
- 在小鼠模型中,准PTHrP1-34/副甲状腺激素1受体轴表明对肺纤维化有减弱作用.
结论:
- 来自支气管上皮细胞的PTHrP1-34有助于IPF的发病.
- PTHrP1-34/副甲状腺激素1受体轴代表了IPF治疗的有前途的治疗标.
