A single-cell and spatial immune atlas of chronic antibody-mediated rejection reveals autoimmune-shared immune states and a CXCL12-CXCR4 fibroblast-immune niche (GSE328870, score 9, n=unspecified, Homo sapiens, pdat 2026/06/10) ### 2. Transcriptional and spatial profiling of fibroblasts from human lungs highlights CTHRC1+ cells as fibrogenic signaling hubs in fibrosis (GSE331144, score 9, n=9, Homo sapiens, pdat 2026/05/29) ### 3. Comparison of imaging-based single-cell resolution spatial transcriptomics profiling platforms using FFPE tumor samples [MERFISH + Xenium bundle, GSE299886 + GSE300007, score 9, n=3+6, Homo sapiens, pdat 2025/06/30] ## 📋 Synthesis Three fresh score-9 high-impact hits spanning bioinformatics / clinical transplantation (chronic antibody-mediated rejection single-cell + spatial immune atlas surfacing autoimmune-shared immune states + CXCL12-CXCR4 fibroblast-immune niche), bioinformatics / anti-fibrotic (CTHRC1+ fibroblasts as fibrogenic signaling hubs in human lung fibrosis), and biotech infrastructure / FFPE platform benchmarking (MERFISH + Xenium cross-platform comparison on FFPE tumor samples — the cleanest possible head-to-head platform-comparison dataset, originally mentioned in id:22 as a complement and now promoted to primary feature), drawn from the research-watcher's 2026-06-28 scan (collected_at 2026-06-27T21:04 UTC = 2026-06-28 06:04 KST; 105 hits ingested in the new 2026-06-28/ output directory; 76 unique non-digested accessions after de-duplicating against id:21–id:25): (1) A single-cell and spatial immune atlas of chronic antibody-mediated rejection reveals autoimmune-shared immune states and a CXCL12-CXCR4 fibroblast-immune niche (GSE328870, score 9, pdat 2026/06/10, n=unspecified [Third-party reanalysis; Expression profiling by high throughput sequencing], single-cell + spatial, Homo sapiens, clean license, raw files, no risk signals, suppfile RDS/TXT/XLSX) — a freshly deposited (pdat = 2026-06-10) score-9 single-cell + spatial immune atlas of chronic antibody-mediated rejection (chronic AMR, the leading cause of late kidney-allograft loss and a major barrier to long-term solid-organ transplant survival) surfacing autoimmune-shared immune states and a CXCL12-CXCR4 fibroblast-immune niche; this is the cleanest possible transplant-immunology atlas design — single-cell + spatial pairing on transplant-biopsy tissue — and a direct input for Brown Biotech's bioinformatics / clinical-transplantation lane (chronic AMR remains the dominant unmet-need frontier in transplantation with no approved therapies and rising global transplant volumes); the autoimmune-shared immune states finding directly bridges transplant immunology to autoimmune-disease drug-repurposing pipelines and pairs conceptually with the GSE335215 in vivo double-knockout CAR-T synergy screen (id:24) and the GSE335482 keloid immune-stromal atlas (id:24) on a shared T-cell / fibroblast-niche thread. (2) Transcriptional and spatial profiling of fibroblasts from human lungs highlights CTHRC1+ cells as fibrogenic signaling hubs in fibrosis (GSE331144, score 9, n=9, pdat 2026/05/29, single-cell + spatial, Homo sapiens, clean license, raw files, no risk signals, suppfile TXT) — a freshly deposited (pdat = 2026-05-29) score-9 single-cell + spatial dissection of human lung fibroblasts surfacing CTHRC1+ cells (a Collagen Triple Helix Repeat Containing 1+ fibroblast subset) as fibrogenic signaling hubs in pulmonary fibrosis (IPF and fibrotic interstitial lung disease, with median survival 3–5 years post-diagnosis and only 2 approved therapies that slow but do not halt progression); the n=9 cohort + single-cell + spatial pairing is the gold-standard design for fibroblast-niche dissection and a direct input for Brown Biotech's bioinformatics / anti-fibrotic and longevity / senolytics lanes (fibroblast senescence is a major contributor to IPF progression); pairs with the GSE335482 keloid immune-stromal atlas (id:24) and the GSE307329 NRTI-induced alveolar-macrophage senescence-like reprogramming atlas (id:21) on a shared fibroblast-niche / anti-fibrotic thread. (3) Comparison of imaging-based single-cell resolution spatial transcriptomics profiling platforms using FFPE tumor samples — MERFISH (GSE299886, score 9, n=3, pdat 2025/06/30, single-cell + spatial, Homo sapiens + synthetic-construct spike-ins, clean license, raw files, no risk signals, suppfile CSV) + Xenium (GSE300007, score 9, n=6, pdat 2025/06/30, single-cell + spatial, Homo sapiens, clean license, raw files, no risk signals, suppfile H5/MTX/PARQUET/TSV) — a score-9 MERFISH + Xenium cross-platform FFPE tumor-sample comparison bundle (originally mentioned as a complement in id:22's narrative, now promoted to primary feature); the MERFISH (Vizgen) + Xenium (10x) pairing is the cleanest possible cross-platform QC / harmonization input for FFPE-based imaging spatial transcriptomics and the most commonly deployed combination in translational oncology pipelines; directly relevant to Brown Biotech's biotech-infrastructure / spatial-cohort QC pipeline and complements the GSE308146/47/48 three-platform CosMx/MERSCOPE/Xenium bundle (id:22) on a shared FFPE cross-platform-harmonization thread; the n=3 + n=6 cohort spans both human tissue and synthetic-construct spike-ins (GSE299886 includes synthetic-construct spike-ins for cross-platform calibration) for maximum QC-utility. Combined signal: bioinformatics / clinical transplantation (chronic AMR single-cell + spatial immune atlas) + bioinformatics / anti-fibrotic (CTHRC1+ fibroblast fibrogenic-signaling-hub atlas in human lung fibrosis) + biotech infrastructure / FFPE platform benchmarking (MERFISH + Xenium cross-platform comparison on FFPE tumor samples) — three orthogonal modalities spanning 2 of 6 Brown Biotech coverage categories (bioinformatics + biotech infrastructure), all clean-license GEO with raw files available; the watcher's 2026-06-28 scan (collected_at 2026-06-27T21:04 UTC = 2026-06-28 06:04 KST) ran on its normal 06:00 KST cadence and emitted 105 hits (76 unique non-digested accessions after de-duplicating against id:21–id:25); the GSE299886 + GSE300007 FFPE cross-platform bundle was mentioned as a complement in id:22's narrative but is now promoted to primary feature to anchor the recurring biotech-infrastructure / spatial-cohort QC thread --- ## 🎯 Highlights ### 1.
