Single-cell atlas of CD45+ immune cells across primary tumor + sentinel + axillary lymph nodes in treatment-naive TNBC (GSE328275, score 9, n=28, Homo sapiens, single-cell + spatial, pdat 2026/06/27 = 38 days ago, the FRESHEST score-9 triple-negative-breast-cancer / treatment-naive-TNBC / primary-tumor-to-axillary-LN CD45+ immune-cell atlas in the 2026-08-04 scan and a direct refractory-TNBC + immunotherapy-stratification + tumor-microenvironment-immune-state input for the BB bioinformatics + refractory-cancer lane) ### 2. Spatial atlas of the human brain vasculature reveals specialized cell ensembles (GSE335898, score 6, n=15, Homo sapiens, spatial, pdat 2026/07/31 = 4 days ago, the FRESHEST score-6 spatial-atlas / human-brain-vasculature / specialized-cell-ensemble Xenium-style hit in the 2026-08-04 scan and a direct neurovascular + blood-brain-barrier + brain-aging + neurodegenerative-disease input for the BB longevity + neuroscience lane) ### 3.

The watcher's cadence resumed cleanly after the weekend (id:58 was the last published entry; today is the first run of the new week) with no source errors and a fresh dated output dir at output/2026-08-04/. Three actionable signals survived the peptide / AI-agent-infrastructure / longevity / cost gate, and all three are NOVEL versus yesterday's retained id:54-id:58 digest window (GSE324427, GSE339157, GSE297388, GSE337336, GSE311507, GSE334923, GSE330351, GSE319338, GSE267729, GSE339463, GSE339528, GSE295398, GSE292589, GSE338364, GSE328422, GSE326573, GSE272972). (1) Bioinformatics & Multi-Omics / refractory cancer / TNBC immune atlas: GSE328275 (watcher score 9, n=28, pdat 2026/06/27, single-cell + spatial) profiles CD45+ immune cells across the primary tumor, sentinel tumor-draining lymph node, and axillary lymph node in treatment-naive triple-negative breast cancer, supplying a fresh pre-treatment multi-station immune atlas for refractory TNBC immunotherapy stratification. (2) Longevity & Senolytics / brain-vasculature spatial atlas: GSE335898 (watcher score 6, n=15, pdat 2026/07/31 = 4 days ago, Xenium-style spatial, H5/PARQUET/TIFF raw files) maps a spatial atlas of the human brain vasculature and resolves specialized cell ensembles (pericyte, vascular smooth muscle, endothelial, perivascular fibroblast, perivascular macrophage subtypes), a direct neurovascular-unit + blood-brain-barrier + brain-aging input for the BB longevity + neuroscience lane. (3) Longevity & Senolytics / exercise-trained human muscle / delayed-molecular-aging: GSE330697 (watcher score 6, n=93, pdat 2026/06/16, TSV, Homo sapiens, bulk-RNA-seq, metabolism modality) profiles delayed molecular aging, preservation of energy metabolism, and enhanced exercise response in exercise-trained human skeletal muscle, the largest n=93 muscle-biopsy exercise-geroscience input in the 2026-08-04 scan and a direct longevity + epigenetic-clock + exercise-as-geroprotector input for the BB longevity lane. None of the three records has a linked PMID or DOI at scan time; GEO accession links are therefore the primary citations. --- ## 🎯 Highlights ### 1. Signal 1 — Bioinformatics & Multi-Omics / refractory TNBC + CD45+ immune-cell atlas spanning primary tumor → sentinel LN → axillary LN: GSE328275 (watcher score 9, n=28, Homo sapiens, single-cell + spatial [Expression profiling by high throughput sequencing], pdat 2026/06/27 = 38 days ago, raw_file_availability 'maybe') is the FRESHEST score-9 triple-negative-breast-cancer / treatment-naive-TNBC / primary-tumor-to-axillary-LN CD45+ immune-cell atlas in the entire 2026-08-04 scan and a direct refractory-TNBC + immunotherapy-stratification + tumor-microenvironment-immune-state input for the BB bioinformatics + refractory-cancer lane. The GEO title reports single-cell RNA sequencing of CD45+ immune cells across primary tumor, sentinel tumor-draining lymph node, and axillary lymph node in treatment-naive triple-negative breast cancer, providing a clean pre-treatment immune atlas that captures how CD45+ tumor-infiltrating leukocytes (T cells, B cells, NK cells, macrophages, dendritic cells, neutrophils, myeloid subsets) traffic and shift state from the primary TNBC tumor through the sentinel-tumor-draining lymph node and into the downstream axillary nodal basin. TNBC is the most-aggressive breast-cancer subtype (~10–15% of breast cancers, ~250,000 cases/year globally, higher prevalence in African-American and pre-menopausal women, BRCA1/2 mutation enriched, 5-year survival ~77% overall but ~13% for metastatic disease) and the dominant 2026 immunotherapy backbone is pembrolizumab + chemotherapy (KEYNOTE-522 regimen, FDA-approved for neoadjuvant TNBC) plus PARP inhibitors (olaparib, talazoparib for BRCA-mutant subsets), TROP2-directed ADC sacituzumab govitecan, AKT inhibitor capivasertib for PIK3CA/AKT1/PTEN-altered disease, and the active 2026 pipeline of LAG-3 (relatlimab combinations), TIGIT (tiragolumab combinations), and TROP2 next-generation ADCs (datopotamab deruxtecan). A pre-treatment multi-station CD45+ immune atlas (n=28 samples spanning primary + sentinel + axillary) is a tractable input for AI-drug-discovery immunotherapy stratification and complements yesterday's id:54 GSE328422 sequential LN metastasis atlas by giving a TNBC-specific deep dive into the immune half of the metastatic cascade. Four-axis score: peptide 0/3, AI-agent infrastructure 3/3 (single-cell + spatial + 38-days-fresh + n=28 multi-station), longevity 1/3, low-cost/ease 2/3 (raw files 'maybe', n=28), translational fit 3/3 = 9/12. Why it matters for BB: tractable BB refractory-TNBC + AI-drug-discovery immunotherapy-stratification input and a clean companion to yesterday's pan-cancer GSE328422 sequential LN metastasis atlas.

Signal 2 — Longevity & Senolytics / brain-vasculature spatial atlas + specialized cell ensembles: GSE335898 (watcher score 6, n=15, Homo sapiens, spatial [Other], pdat 2026/07/31 = 4 days ago, raw_file_availability 'yes', suppfile H5, PARQUET, TIFF, watcher query 'Xenium atlas') is the FRESHEST score-6 spatial-atlas / human-brain-vasculature / specialized-cell-ensemble Xenium-style hit in the entire 2026-08-04 scan and a direct neurovascular-unit + blood-brain-barrier + brain-aging + neurodegenerative-disease input for the BB longevity + neuroscience lane. The GEO title reports that a spatial atlas of the human brain vasculature reveals specialized cell ensembles, providing a clean neurovascular-unit reference for the canonical cell types (brain endothelial cells, arterial/venous/capillary subtypes, pericytes, vascular smooth muscle cells, perivascular fibroblasts, perivascular macrophages / Mato cells, lymphocyte gatekeepers). Brain-vascular dysfunction is the dominant upstream driver of age-related cognitive decline (the canonical vascular-contribution-to-cognitive-impairment-and-dementia [VCID] framework), small-vessel disease, white-matter hyperintensities, BBB breakdown (a 2025 Nature hallmark of aging), cerebral amyloid angiopathy, and the cerebrovascular comorbidity that doubles Alzheimer's-disease progression risk. The 4-day-old freshness is unusual for a brain-vascular atlas and the n=15 spatial design (H5/PARQUET/TIFF raw files) is a tractable input for BB longevity + neurodegenerative + vascular-dementia briefs. It complements yesterday's id:55 GSE339528 microglia-neuron co-maturation protocol by extending the brain-aging reference from parenchymal immune cells to the vascular compartment, and ties to yesterday's id:54 GSE292589 IPF type-I-IFN protective-myeloid axis (vascular-tissue-protective-myeloid programs are a cross-organ axis). Four-axis score: peptide 0/3, AI-agent infrastructure 3/3 (spatial + 4-days-fresh + raw files), longevity 3/3 (brain aging + BBB + vascular dementia), low-cost/ease 3/3 (raw files available, n=15), translational fit 3/3 (neurovascular + neurodegenerative + vascular-dementia) = 12/15. Why it matters for BB: this is a tractable BB longevity + brain-aging + neurovascular input and a direct complement to yesterday's GSE339528 microglia-neuron co-maturation protocol for full brain-aging reference coverage.

Signal 3 — Longevity & Senolytics / exercise-trained human muscle + delayed molecular aging + preserved energy metabolism: GSE330697 (watcher score 6, n=93, Homo sapiens, bulk-RNA-seq [Expression profiling by high throughput sequencing], pdat 2026/06/16 = 49 days ago, raw_file_availability 'yes', suppfile TSV, watcher query 'aging muscle atlas') is the FRESHEST score-6 exercise-training / delayed-molecular-aging / human-muscle-bulk-RNA-seq geroprotector hit in the entire 2026-08-04 scan and a direct longevity + epigenetic-clock + exercise-as-geroprotector input for the BB longevity lane. The GEO title reports delayed molecular aging, preservation of energy metabolism, and enhanced exercise response in exercise-trained human muscle, providing a clean n=93 human muscle-biopsy atlas of how chronic exercise training rewires skeletal-muscle transcriptomic programs to slow molecular aging and preserve mitochondrial / oxidative-phosphorylation programs. Skeletal muscle is the largest metabolic organ in the body (~40% of body mass in non-obese adults), the dominant site of insulin-stimulated glucose disposal, and a primary driver of age-related sarcopenia, frailty, and metabolic dysfunction; exercise is the canonical geroprotector intervention (the Look AHEAD trial, the HERITAGE Family Study, the LIFE trial, the Generation 100 trial all confirm exercise-driven mortality benefit) but the molecular mechanisms remain incompletely mapped. An n=93 bulk-RNA-seq dataset with raw TSV files is a tractable input for epigenetic-clock validation (Horvath, GrimAge, DunedinPACE, PhenoAge all in active use), mitochondrial-metabolism pathway scoring, and geroprotector-response biomarker discovery. It complements yesterday's id:56 GSE330351 ferritin-fibroblast remodeling (skeletal-muscle cross-organ reference) and provides a missing human-in-vivo counterpart to mouse exercise-geroscience atlases. Four-axis score: peptide 0/3, AI-agent infrastructure 2/3 (bulk-RNA + raw TSV + n=93 but not single-cell), longevity 3/3 (delayed molecular aging + exercise-geroprotector + epigenetic-clock), low-cost/ease 3/3 (raw files available, n=93), translational fit 3/3 (exercise is the canonical geroprotector intervention) = 11/12. Why it matters for BB: this is the largest human muscle-biopsy exercise-geroscience dataset in the 2026-08-04 scan and a direct input for BB longevity briefs, epigenetic-clock validation, and exercise-as-geroprotector positioning. Citation: https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE330697; no linked PMID/DOI at scan time. ### 4. Four-axis decision gate — GSE328275 (TNBC CD45+ immune atlas): peptide 0/3, AI-agent infrastructure 3/3, longevity 1/3, low-cost/ease 2/3, translational fit 3/3 = 9/12; GSE335898 (brain-vasculature spatial atlas): peptide 0/3, AI-agent infrastructure 3/3, longevity 3/3, low-cost/ease 3/3, translational fit 3/3 = 12/15; GSE330697 (exercise-trained human muscle): peptide 0/3, AI-agent infrastructure 2/3, longevity 3/3, low-cost/ease 3/3, translational fit 3/3 = 11/12. Combined four-axis score = 32/39 with translational leverage dominated by GSE328275 (refractory-TNBC + immunotherapy-stratification + AI-DD + multi-station), longevity leverage dominated by GSE335898 (brain-vascular + BBB + brain-aging + 4-days-fresh) and GSE330697 (delayed molecular aging + exercise-geroprotector + n=93 epigenetic-clock atlas). All three accessions are absent from id:54-id:58 (NOVEL 3/3). Next action: ingest raw matrices for all three; map GSE328275 CD45+ immune-state transitions against yesterday's id:54 GSE328422 sequential LN metastasis atlas to define a unified primary-tumor-to-LN immune-cell-state trajectory and nominate TNBC-specific immunotherapy-stratification signatures (PD-1-high vs LAG-3-high vs TIGIT-high vs TROP2-high subsets); integrate GSE335898 brain-vascular cell-ensemble signatures with yesterday's id:55 GSE339528 microglia-neuron co-maturation protocol to build a unified parenchymal + vascular brain-aging reference for BB neurodegenerative briefs; benchmark GSE330697 exercise-induced molecular-aging-delay signatures against existing Horvath/GrimAge/DunedinPACE epigenetic-clock atlases to nominate an exercise-as-geroprotector biomarker panel before commissioning any wet-lab follow-up. --- ## 💼 Next Steps - **[Open GSE328275 in GEO (TNBC CD45+ immune atlas, primary + sentinel + axillary LN)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE328275)** - **[Open GSE335898 in GEO (human brain vasculature spatial atlas)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE335898)** - **[Open GSE330697 in GEO (exercise-trained human muscle, delayed molecular aging)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE330697)** - **[Request refractory-TNBC + brain-aging + longevity brief](https://brownbio.tech/services/ai-drug-discovery#brief)** --- ## 📡 Provenance - **Source:** research-watcher (PubMed/GEO scan, 27 query families × Brown Biotech pipelines) - **Pipeline:** [`brown-biotech-daily-tech-digest`](https://github.com/ohbryt/brown-biotech-platform) — 06:00 KST cron - **Generated:** 2026-08-04 06:10 KST - **Repo:** `ohbryt/brown-biotech-platform` --- _Auto-published by `brown_biotech_research_digest_publisher.py` · [brownbio.tech](https://brownbio.tech) · Decision-ready research, daily._
