    570-BayesPrism: Cell Type and Gene Expression Deconvolution

    Researchers have developed a new statistical tool called BayesPrism to better understand the complex tumor microenvironment by combining different types of genetic data. While traditional single-cell sequencing provides detailed information, it is often too expensive and technically limited for large patient groups, whereas bulk RNA-seq is widely available but lacks cellular detail. BayesPrism uses a Bayesian strategy to accurately identify the specific types of cells within a tumor and determine their unique gene expression levels. This method has proven more reliable than previous techniques, successfully identifying how different immune cells, such as macrophages and T cells, influence patient survival and cancer progression. By applying this tool to various cancers like glioblastoma and melanoma, the study reveals how malignant cells interact with their surroundings to adapt and grow. Ultimately, this software offers a powerful way to utilize existing medical data to discover new clinical biomarkers and potential targets for therapy.References: Chu, T., Wang, Z., Pe’er, D. et al. Cell type and gene expression deconvolution with BayesPrism enables Bayesian integrative analysis across bulk and single-cell RNA sequencing in oncology. Nat Cancer 3, 505–517 (2022). doi.org

    569-SpaceTracer: High-Resolution Spatial Lineage Tracing

    The paper introduces SpaceTracer, a new computational framework designed to identify somatic mutations directly from spatial transcriptomics data. By detecting these genetic alterations, the tool allows researchers to perform lineage tracing within the natural architecture of human tissues, bypasssing the need for invasive genetic manipulations. The authors demonstrate that this method can effectively reconstruct the evolutionary history of tumors, revealing how specific cell populations migrate and interact within their environment. Application of the tool to cutaneous squamous cell carcinoma uncovered previously hidden migratory patterns in non-tumor cells and detailed how mutant B cells infiltrate malignant areas. Ultimately, SpaceTracer offers a high-resolution platform for studying tumor-immune ecosystems and complex developmental processes by integrating genomic mutations with spatial gene expression.References: Yang Z, Yao M, Yang Q, et al. Detection of Somatic Point Mutations Directly from Spatial Transcriptomics Enables in vivo Spatiotemporal Lineage Tracing[J]. bioRxiv, 2026: 2026.02. 04.703493.

    568-Seq-Scope-X: Submicrometer Spatial Multi-omics

    This research manuscript introduces Seq-Scope-X, a novel spatial biology platform that achieves subcellular and nanoscale resolution by integrating sequencing technology with tissue expansion. By embedding biological samples in an expandable hydrogel and enlarging them before molecular capture, the method overcomes the physical resolution limits of traditional next-generation sequencing. The authors demonstrate its versatility by mapping transcriptomic and proteomic data across diverse tissues, including the liver, brain, and spleen. Their findings highlight the ability to distinguish between nuclear and cytoplasmic gene expressions, revealing that a cell's internal compartments can display distinct functional states. Additionally, the technology is compatible with DMAA-based chemistry, pushing spatial analysis toward a true nanoscale regime. Ultimately, this approach provides a high-throughput, cost-effective means to explore complex tissue architecture at a level of detail previously reserved for specialized optical microscopy.References: Anacleto A, Cheng W, Feng Q, et al.

    567-HistoSweep for Digital Pathology and Omics

    Researchers have introduced HistoSweep, a computationally efficient and scalable framework designed for high-resolution tissue quality control in digital pathology and spatial omics. The tool addresses a critical gap in the field by moving beyond simple foreground-background separation to generate cellular-resolution masks that exclude artifacts, acellular voids, and noise. By integrating color statistics, texture descriptors, and adaptive thresholding, HistoSweep preserves biologically meaningful microstructures without requiring expensive GPU resources. Experiments across 25 diverse datasets demonstrate that the system consistently outperforms existing methods, enhancing visualization and improving the accuracy of cell-type predictions. Furthermore, it serves as a vital safeguard for spatial transcriptomics, identifying data integrity issues like transcript leakage and image misalignment. Ultimately, HistoSweep provides a foundational preprocessing step that ensures more reliable and reproducible biological interpretations of billion-pixel images.References: Schroeder A, Yu X, Li W, et al. HistoSweep enables cellular-resolution tissue quality control for gigapixel images in digital pathology and spatial omics[J]. bioRxiv, 2026: 2026.01. 30.702675.

    566-The Landscape of HumanTuberculosis Granulomas

    This research utilizes multiplexed ion beam imaging (MIBI-TOF) to construct a spatial atlas of the human tuberculosis (TB) granuloma, revealing how immune cell organization dictates disease progression. By analyzing archival tissues, the authors identified eight distinct microenvironments where specific myeloid and lymphoid cells interact, highlighting a specialized myeloid core characterized by immunosuppressive proteins like PD-L1 and IDO1. Interestingly, while these regulatory markers are prevalent in active lesions, the typical T cell exhaustion seen in cancer is absent, suggesting a unique myeloid-mediated suppression mechanism. To validate these findings, the study integrated transcriptomic data from over 1,500 patients, proving that elevated PD-L1 levels in the blood can predict the transition from latent to active TB. Ultimately, this work provides a framework for understanding why some infections persist and suggests that host-directed therapies must account for the local spatial dynamics of the immune response.References: McCaffrey, E.F., Donato, M., Keren, L. et al.

    565-Planetary Microbiome Structure and Global Gene Flow

    This research presents a planetary-scale analysis of over 85,000 metagenomes to establish a comprehensive framework for understanding global microbial habitats. By integrating taxonomic and functional data, the authors identify distinct habitat clusters across aquatic, terrestrial, anthropogenic, and host-associated environments. A key finding is the role of generalist species, which possess the metabolic versatility to bridge ecologically disparate boundaries and facilitate horizontal gene transfer. These generalists act as critical mediators for the global dissemination of antimicrobial resistance (AMR), moving genes from human-impacted areas like wastewater into diverse environmental settings. The study ultimately demonstrates how environmental filtering and human activity jointly structure the genomic adaptations and connectivity of the Earth's microbiome. This framework provides a vital tool for monitoring microbial gene flow and its implications for both environmental and public health.References: Kim C Y, Podlesny D, Schiller J, et al. Planetary microbiome structure and generalist-driven gene flow across disparate habitats[J]. bioRxiv, 2025: 2025.07. 18.664989.

    564-Sensory Neurons Drive Immune Exclusion in Breast Cancer

    This research investigates how perineural invasion (PNI) serves as a critical driver of treatment resistance in triple-negative breast cancer (TNBC). The studies reveal that sensory neurons within the tumor microenvironment release a signaling molecule called CGRP, which interacts with fibroblasts to promote excessive collagen deposition. This structural reorganization creates a physical barrier that prevents immune cells from attacking the tumor, thereby shielding the cancer from immunotherapy. Clinical data from multiple cohorts confirm that higher nerve density correlates with poorer survival and increased metastasis. To combat this, the authors suggest that using CGRP inhibitors—originally designed for migraines—can dismantle this barrier. When combined with anti-PD-1 therapy, these inhibitors successfully restore immune infiltration and significantly improve the efficacy of cancer treatments in experimental models.References: Zhang S W, Wang H, Xiao Y, et al. Sensory neurons drive immune exclusion by stimulating a dense extracellular matrix in the breast cancer tumor microenvironment[J]. Cell, 2026.
