【assistant】
已完成 n118 审计：IL-1/MyD88 的确比 TNF/IL-6 更上游，尤其在 HSC inflammaging、microbiome-driven inflammaging、emergency myelopoiesis 和 Tet2+/− CH 这条链上更有“总开关”味道；但目前仍缺少全身寿命/多器官健康寿命级证据，因此还不能升级为通用长寿瓶颈。
我还把这一判断沉淀成了长期记忆：
- `IL-1/MyD88 outranks TNF/IL-6 as an upstream screening candidate, but not as a universal bottleneck`
