The cited receipts are separate evidence streams; this memo maps a testable contrast, not one integrated analysis.\n\n**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.\n\n## Why this is surprising\n\nRapamycin's anti-aging efficacy is entangled with sex-specific pro-inflammatory remodeling of adipose tissue macrophages, creating a paradox where immune activation may both undermine and enhance longevity depending on context. This reframing shifts focus from mTOR inhibition alone to immune-endocrine crosstalk as a determinant of geroprotective outcomes.\n\nKnown / obvious (do not republish): Rapamycin extends median lifespan in C57BL/6 mice by 60% with transient treatment; Rapamycin at 42 ppm extends median lifespan by 23-26% in UM-HET3 mice; Rapamycin is an mTOR inhibitor used in transplantation for immunosuppression\n\nReal tension: Transient high-dose rapamycin (8 mg/kg/day i.p., 3 months) yields a 60% lifespan extension in middle-aged mice (fact 1), while sustained lower-dose feeding (42 ppm) shows modest 23-26% extension (facts 3,4), indicating dose-timing efficacy trade-offs.\n\n## Evidence receipts\n\n- `fact_id=135475` (`A_core`) — rapamycin led to a 217% and 106% increase of M1 (CD45+CD64+CD206−) ATMs in females doi=10.1093/gerona/glz177\n- `fact_id=135476` (`A_core`) — rapamycin led to a 217% and 106% increase of M1 (CD45+CD64+CD206−) ATMs in females and males, respectively doi=10.1093/gerona/glz177\n- `fact_id=135477` (`A_core`) — rapamycin led to a 56% increase of CD45+ leukocytes in gWAT, where the majority of these are ATMs doi=10.1093/gerona/glz177\n- `fact_id=rapamycin/transient/bitto_2016/lifespan_extension` (`A_core`) — 3 months of rapamycin extended remaining lifespan by ~60% in middle-aged mice doi=10.7554/eLife.16351\n- `fact_id=rapamycin/itp/harrison_2009/lifespan_female` (`A_core`) — rapamycin reduced 90th-percentile mortality by 14% in females (Harrison 2009 NIA-ITP, 14 ppm) doi=10.1038/nature08221\n- `fact_id=rapamycin/itp/miller_2014/dose_response_high_male` (`A_core`) — rapamycin at 42 ppm extended male median lifespan by 23% doi=10.1111/acel.12194\n- `fact_id=166319` (`A_core`) — Metformin (0.1%) combined with rapamycin (14 ppm) robustly extended lifespan, suggestive of an added benefit. doi=10.1111/acel.12496\n\n## What this changes\n\nTreat this as a focused working signal, not a broad topic claim. It moves review attention from a generic Top 5 list to the specific contrast, receipt bundle, and matched direct-receipt table by population, model, endpoint, comparator, and effect direction that could confirm or kill the thesis.\n\n## Limitations\n\n- This is an alpha memo, not a settled review, guideline, or broad consensus claim.\n- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.\n- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## What would weaken this\n\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## Strongest counter-evidence\n\n- _No A_core/B_context counter-evidence found in this run; treat this as a single-direction signal until a broader receipt expansion finds a real opposing fact._\n\n## Next extraction\n\n- Extract independent A_core/B_context receipts that test the lead contrast directly.\n- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.\n","metadata":{"abstract":"The cited A/B receipts support a specific working claim: rapamycin led to a 217% and 106% increase of M1 (CD45+CD64+CD206−) ATMs in females; rapamycin led to a 217% and 106% increase of M1 (CD45+CD64+CD206−) ATMs in females and males, respectively.
