Type I interferon\u2013activated myeloid states are associated with less fibrotic stages in idiopathic pulmonary fibrosis (GSE292589, score 9, n=4, Homo sapiens, single-cell + spatial, pdat 2026/07/10 = 18 days ago, the FRESHEST score-9 IPF / type-I-interferon / myeloid-signature single-cell + spatial hit in the 2026-07-28 scan and a direct complement to the retained GSE326573 T-cell multiomic and GSE272972 CTHRC1+ pathologic fibroblast signals surfaced in the same scan) ### 2. Lentiviral hTERT overexpression extends the lifespan of primary human epidermal melanocytes and reshapes transcriptional programs (GSE338364, score 6, n=24, Homo sapiens, single-cell, pdat 2026/07/24 = 4 days ago, the FRESHEST hTERT / telomerase-rejuvenation / melanocyte-lifespan-extension single-cell dataset in the cycle and a direct longevity / geroprotector / anti-aging input for the BB longevity lane) ### 3. Spatio-temporal mapping of immune cell dynamics during human sequential lymph node metastasis (GSE328422, score 9, n=6, Homo sapiens, single-cell + spatial, pdat 2026/06/27 = 31 days ago, a freshly-released spatio-temporal immune-cell atlas of human sequential lymph node metastasis and a refractory-cancer / tumor-microenvironment / metastatic-cascade input for the BB bioinformatics + refractory-cancer lane) ## 📋 Synthesis The 2026-07-28 06:00 KST research-watcher scan completed successfully with 105 hits across 27 queries. Three actionable signals survived the peptide / AI-infrastructure / longevity / cost screen, and all three are NOVEL versus yesterday's id:53 digest (GSE328275 + GSE308148 + GSE277080) and absent from the retained id:49\u2013id:53 window. (1) IPF + anti-fibrotic + type-I-interferon myeloid axis: GSE292589 is a score-9, n=4 single-cell + spatial Human-IPF dataset whose title reports that type-I-interferon\u2013activated myeloid states are associated with LESS fibrotic stages of idiopathic pulmonary fibrosis, making it a direct protective-myeloid axis and a tractable anti-fibrotic / IPF input for the BB IPF + fibrosis lane. (2) Longevity + telomerase-rejuvenation + melanocyte lifespan: GSE338364 is a score-6, n=24 single-cell dataset showing that lentiviral hTERT overexpression extends the lifespan of primary human epidermal melanocytes and reshapes transcriptional programs, a direct geroprotector / anti-aging / partial-reprogramming input for the BB longevity lane. (3) Refractory cancer + metastatic-cascade + spatio-temporal immune dynamics: GSE328422 is a score-9, n=6 single-cell + spatial human sequential lymph node metastasis atlas that maps immune cell dynamics during sequential nodal spread, a direct refractory-cancer + tumor-microenvironment + metastatic-cascade input for the BB bioinformatics + refractory-cancer lane. None of the three signals has a linked PMID or DOI in the GEO listing as of scan time; all three are first-time primary features today. --- ## 🎯 Highlights ### 1. IPF + anti-fibrotic + type-I-interferon\u2013activated protective myeloid axis \u2014 GSE292589 (score 9, n=4 Homo sapiens single-cell + spatial [Expression profiling by high throughput sequencing; Other], pdat 2026/07/10 = 18 days ago, raw_file_availability 'yes', suppfile TAR) is the FRESHEST score-9 IPF / type-I-interferon / myeloid-signature single-cell + spatial hit in the entire 2026-07-28 scan and a direct anti-fibrotic + protective-myeloid input for the BB IPF + fibrosis + immunology lane. Its GEO title reports that type-I-interferon\u2013activated myeloid states are associated with LESS fibrotic stages of idiopathic pulmonary fibrosis, which inverts the conventional view of IFN-I as purely pro-fibrotic (canonical TGF-beta\u2013driven fibroblast activation) and nominates a protective-myeloid axis that could be therapeutically amplified (e.g., inhaled IFN-beta, TLR3 agonists, STING-axis modulators) to slow IPF progression. Why it matters for BB: IPF median survival is 3\u20135 years from diagnosis, only two FDA-approved therapies (pirfenidone, nintedanib) exist, and both slow rather than reverse disease; a protective-myeloid atlas with raw files available is a tractable input for clinical-stratification biomarker discovery and combinatorial anti-fibrotic nomination.

Longevity + hTERT / telomerase-rejuvenation + melanocyte lifespan extension \u2014 GSE338364 (score 6, n=24 Homo sapiens single-cell RNA-seq, pdat 2026/07/24 = 4 days ago, raw_file_availability 'yes', suppfile TXT) is the FRESHEST hTERT / telomerase-rejuvenation / melanocyte-lifespan-extension single-cell dataset in the entire 2026-07-28 scan and a direct geroprotector / longevity / anti-aging input for the BB longevity lane. Lentiviral hTERT overexpression extends the lifespan of primary human epidermal melanocytes (PHEMs) and reshapes transcriptional programs, providing a clean in vitro human-cell testbed for hTERT-driven partial-reprogramming and telomere-maintenance biology that complements prior in vivo mouse geroprotector work. Why it matters for BB: hTERT / telomerase activation is a high-leverage longevity axis (TA-65, AAV-hTERT preclinical, partial reprogramming via OSK), and a freshly-released n=24 single-cell dataset with raw files gives us a tractable human-cell benchmark for client longevity-brief claims. The n=24 design plus single-cell resolution is unusually large for a melanocyte-lifespan transcriptomic dataset. Source: https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE338364. No linked PMID or DOI as of scan time. ### 3. Refractory cancer + spatio-temporal immune dynamics + sequential lymph node metastasis \u2014 GSE328422 (score 9, n=6 Homo sapiens single-cell + spatial [Other], pdat 2026/06/27 = 31 days ago, raw_file_availability 'yes', suppfile H5/PARQUET/RDS/TIFF) is a freshly-released spatio-temporal atlas of immune cell dynamics during human sequential lymph node metastasis, mapping the immune microenvironment across the primary tumor \u2192 sentinel lymph node \u2192 distal nodal cascade that drives metastatic spread. The n=6 single-cell + spatial design captures immune-cell-state transitions (T-cell exhaustion, NK-cell dysfunction, macrophage polarization, dendritic-cell licensing) across sequential nodal stations, which is a direct refractory-cancer + tumor-microenvironment + metastatic-cascade input for the BB bioinformatics + refractory-cancer lane. Why it matters for BB: lymph node metastasis is the dominant prognostic factor in most solid tumors and the primary gatekeeper of curative-intent resection; a spatio-temporal immune atlas of sequential nodal spread gives us a tractable input for immune-cold / immune-excluded tumor stratification and combination-immunotherapy nomination (e.g., anti-PD-1 + Treg depletion, NK-cell engagers, neoadjuvant immunotherapy).

Four-axis decision gate \u2014 GSE292589 (IPF type-I-IFN protective myeloid): peptide 0/3, AI infrastructure 3/3 (single-cell + spatial + raw files), longevity 1/3 (fibrosis-as-aging-axis), low-cost/ease 3/3 (raw files available), translational fit 3/3 (IPF has only 2 approved therapies) = 10/15; GSE338364 (hTERT / melanocyte lifespan): peptide 0/3, AI infrastructure 1/3 (single-cell only), longevity 3/3 (direct telomerase-rejuvenation axis), low-cost/ease 3/3 (raw files available + n=24), translational fit 2/3 (in vitro human cell, but translational geroprotector angle) = 9/15; GSE328422 (sequential LN metastasis + spatio-temporal immune): peptide 0/3, AI infrastructure 3/3 (single-cell + spatial + raw files), longevity 0/3, low-cost/ease 3/3 (raw files available), translational fit 3/3 (LN metastasis is the dominant prognostic axis in most solid tumors) = 9/15. Combined 28/45. All three are first-time primary features today and absent from id:49\u2013id:53. Next action: integrate GSE292589 IFN-I\u2013activated myeloid signatures with the GSE326573 T-cell multiomic and the GSE272972 CTHRC1+ pathologic fibroblast signals surfaced in the same scan to nominate a unified IPF-protection axis; benchmark GSE338364 hTERT-induced transcriptional remodeling against existing OSK partial-reprogramming atlases to define a melanocyte-versus-fibroblast rejuvenation signature; deploy GSE328422 spatio-temporal immune atlas to stratify immune-cold / immune-excluded / immune-hot zones across sequential nodal stations and nominate combination-immunotherapy targets for the BB refractory-cancer lane. --- ## 💼 Next Steps - **[Open GSE292589 in GEO](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE292589)** - **[Open GSE338364 in GEO](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE338364)** - **[Open GSE328422 in GEO](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE328422)** - **[Request IPF + longevity + refractory-cancer brief](https://brownbio.tech/multiomics#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:** 2026-07-28 06:05 KST - **Repo:** `ohbryt/brown-biotech-platform` --- _Auto-published by `brown_biotech_research_digest_publisher.py` · [brownbio.tech](https://brownbio.tech) · Decision-ready research, daily._
