Hermansky-Pudlak Syndrome (HPS) is a rare, genetic, multisystem disorder characterized by oculocutaneous albinism (OCA), bleeding diathesis, immunodeficiency, granulomatous colitis, and pulmonary fibrosis. HPS pulmonary fibrosis (HPS-PF) occurs in 100% of patients with subtype HPS-1 and has a similar presentation to idiopathic pulmonary fibrosis. Upon onset, individuals with HPS-PF have approximately 3 years before experiencing signs of respiratory failure and eventual death. This review aims to summarize current research on HPS along with its associated pulmonary fibrosis and its implications for the development of novel treatments. We will discuss the genetic basis of the disease, its epidemiology, and current therapeutic and clinical management strategies. We continue to review the cellular processes leading to the development of HPS-PF in alveolar epithelial cells, lymphocytes, mast cells, and fibrocytes, along with the molecular mechanisms that contribute to its pathogenesis and may be targeted in the treatment of HPS-PF. Finally, we will discuss emerging new cellular and molecular approaches for studying HPS, including lentiviral-mediated gene transfer, induced pluripotent stem cells (iPSCs), organoid and 3D-modelling, and CRISPR/Cas9-based gene editing approaches.
赫尔曼斯基-普德拉克综合征(HPS)是一种罕见的遗传性多系统疾病,其特征为眼皮肤白化病(OCA)、出血素质、免疫缺陷、肉芽肿性结肠炎和肺纤维化。HPS相关性肺纤维化(HPS-PF)在100%的HPS-1亚型患者中出现,其表现与特发性肺纤维化相似。发病时,HPS-PF患者在出现呼吸衰竭迹象及最终死亡前约有3年时间。本综述旨在总结目前关于HPS及其相关肺纤维化的研究,以及其对新型治疗方法开发的影响。我们将讨论该疾病的遗传基础、流行病学以及当前的治疗和临床管理策略。我们继续综述导致肺泡上皮细胞、淋巴细胞、肥大细胞和成纤维细胞中HPS-PF发生的细胞过程,以及促成其发病机制且可能成为HPS-PF治疗靶点的分子机制。最后,我们将讨论研究HPS的新兴细胞和分子方法,包括慢病毒介导的基因转移、诱导多能干细胞(iPSC)、类器官和3D建模,以及基于CRISPR/Cas9的基因编辑方法。
