研究问题
Host resistance to infection is initially determined by how well primed the innate immune system is to respond on first exposure to an invader, yet the mechanisms underlying this priming remain incompletely understood.

Here we found that basal autophagy suppressed the expression of Il1a in alveolar macrophages (AMs) and an otherwise protective innate immune priming against Staphylococcus aureus and influenza A virus (IAV), independently of the microbiome…
核心结论
Here we found that basal autophagy suppressed the expression of Il1a in alveolar macrophages (AMs) and an otherwise protective innate immune priming against Staphylococcus aureus and influenza A virus (IAV), independently of the microbiome and adaptive…；Inactivating autophagy genes in AMs led to elevated expression of IL-1α in AMs, which subsequently enhanced IL-1R-MyD88 signaling in neutrophils and increased the recruitment of myeloid cells to the lung.；As a result, autophagy-deficient mice showed more efficient clearance of S. aureus along with reduced lung damage and inflammation.

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
