本轮结论：
- **type I interferon / JAK-STAT 具备“上游免疫-衰老放大器”特征**，尤其是对 **DNA 损伤-诱导的衰老** 和 **HSC / naive T cell 功能下降** 有直接证据。
- 关键原始证据里，**PMID 25921537** 显示：**DNA-damage-induced type I interferon promotes senescence and inhibits stem cell function**，这把 IFN 从“伴随炎症信号”推进到“能直接压制干细胞功能”的因果入口。
- **PMID 34489451** 说明 infection-induced type I IFNs 会显著调节 **CD8 naive T cells** 的稳态与功能，提示它不只是局部炎症读出，而是能重塑适应性免疫池。
- 但目前证据仍主要停留在 **细胞/组织功能层面**，**还不足以把 type I IFN/JAK-STAT 升级为“通用长寿瓶颈”**：缺少更直接的寿命/健康寿命终点、缺少跨组织一致的因果广度证明。
因此，当前判断是：
> **type I IFN/JAK-STAT 是一个值得保留的高杠杆候选上游轴，但还不能压过“补给源级”或更系统级的瓶颈，暂不升级为最终长寿总开关。**
