2型免疫反应控制蠕虫感染并维持组织稳态,但当控制不当时可导致过敏和纤维化。我们揭示了2型介导的巨噬细胞活化的局部组织特异性增强剂的存在。在肺中,表面活性蛋白A(SP-A)增强IL-4依赖性的增殖和激活肺泡巨噬细胞,加速寄生虫清除和减少肺感染后的肺损伤迁移蠕虫。在腹膜腔和肝脏中,C1 q增强2型巨噬细胞活化是细菌感染后肝脏修复所需的,但导致腹膜透析后组织纤维化。SP-A和C1 q都通过非常规的肌球蛋白18 A(作为细胞表面受体)对巨噬细胞产生作用。我们的结论是,结构相关的防御胶原蛋白SP-A和C1 q是组织特异性因子,通过肌球蛋白18 A许可本地2型反应,寄生虫控制,组织修复和纤维化的后果。
The type 2 immune response controls helminth infection and maintains tissue homeostasis but can lead to allergy and fibrosis when improperly controlled. We reveal the existence of local tissue-specific enhancers of type 2 mediated-macrophage activation. In the lung, surfactant protein A (SP-A) enhanced IL-4-dependent proliferation and activation of alveolar macrophages, accelerating parasite clearance and reducing pulmonary injury following infection with a lung-migrating helminth. In the peritoneal cavity and liver, C1q enhancement of type 2 macrophage activation was required for liver repair following bacterial infection, but resulted in tissue fibrosis following peritoneal dialysis. Both SP-A and C1q generated their effects on macrophages via the unconventional myosin18A that acts as a cell surface receptor. We conclude that the structurally related defense collagens SP-A and C1q are tissue-specific factors that act through myosin18A to license local type 2 responses with consequences for parasite control, tissue repair, and fibrosis.
