Cell Death Differ:上皮和内皮细胞衍生的外泌体调节肺泡巨噬细胞的免疫平衡并影响多种肺部疾病

肺泡巨噬细胞(AMs)能够维持气道的免疫平衡,其紊乱可导致各种肺部疾病,包括急性肺损伤/急性呼吸窘迫综合征(ALI/ARDS)、肺纤维化(PF)、哮喘和慢性阻塞性肺病(COPD)。

肺泡巨噬细胞(AMs)能够维持气道的免疫平衡,其紊乱可导致各种肺部疾病,包括急性肺损伤/急性呼吸窘迫综合征(ALI/ARDS)、肺纤维化(PF)、哮喘和慢性阻塞性肺病(COPD)。

ALI/ARDS涉及单核细胞或中性粒细胞的过度募集,其能够破坏血管内皮屏障并引发血氧交换的障碍。PF是由肺上皮细胞的长期慢性损伤(如长期吸烟或吸毒)所引起的。AMs具有多种表型,其参与炎症反应,调节组织重塑和抗纤维化过程。然而,目前对与肺微环境中AMs调节免疫平衡的分子机制还知之甚少。

在该研究中,研究人员证实,RGS1能够通过PLC-IP3R信号依赖性细胞内Ca2+的响应调节AM细胞亚群的免疫表型,这些表型包括促炎和抗炎、损伤和修复以及促纤维化和抗纤维化的相关表型。

基于Ly6C表达的AMs的ALI/ARDS表型差异

研究人员发现,Flt3+AM和Tie2+AM具有不同的免疫特性,且细胞中RGS1的表达被包含miR-223和miR-27b-3p的外泌体(EXO)所靶向,这些外泌体来自血管内皮细胞(EnCs)和II型肺泡上皮细胞(EpCs-II)。

EpCs-II和EnCs分泌的EXOs对Flt3+和Tie2+ AMs中RGS1表达的影响

进一步的研究显示,AMs的失衡与ALI/ARDS和PF中EnCs和EpCs-II衍生的CD31+和CD74+ EXO外泌体的分泌缺乏相关。而用EXOs治疗可以显著改善内毒素(endotoxin)诱导的ALI/ARDS和博来霉素(bleomycin)诱导的PF。


总而言之,该研究结果揭示,EnC和EpC-II衍生的EXO能够调节AM的免疫平衡,其或可成为潜在的治疗药物。

慢性阻塞性肺疾病(COPD)是一种气道炎症和肺组织损伤的疾病,同样是导致世界范围内人类死亡的一大诱因。在健康的气道中,肺泡巨噬细胞(AMs)相对静止,以避免对各个暴露抗原的炎症反应,这对于气道和环境的稳定的相互作用至关重要。在慢性阻塞性肺疾病中,肺泡巨噬细胞数量会增加并产生更多的促炎介质,有助于肺组织的损伤和炎症。 慢性阻塞性肺疾病患者更容易受到细菌性呼吸道感染,导致肺炎和病情恶化,相应的增加发病
