🧴 Skin & Tissue Atlases
Single-cell spatial transcriptomic analysis of human skin anatomy.
An organ-wide single-cell and spatial transcriptomic atlas of ~1.2 million cells from normal adult human skin maps 45 cell types across 15 anatomical sites. The study defines ten stereotypic multicellular neighborhoods, including a perivascular skin-associated lymphoid tissue–like niche where TNF-centered ligand–receptor networks help organize local immunity.
Impact: A foundational spatial atlas of healthy human skin that charts microanatomical immune niches across the body.

🧠 Neuroimmunology & Brain Disorders
A transcriptomic microglia taxonomy across mouse and human pathologies.
By profiling over one million CNS myeloid cells across more than 30 physiological and disease conditions, the authors build a cross-species taxonomy of 27 microglial superclusters and 192 clusters. Integration with spatial transcriptomics reveals how these immune states are positioned within brain tissue and shaped by local niches, with in vivo perturbations showing dependence on interferon and CSF1R signaling.
Impact: A spatially resolved reference framework for comparing microglial and myeloid states across brain diseases and models.

🧪 Technology & Methods Development
Ultra-precision deconvolution of spatial transcriptomics decodes immune heterogeneity and fate-defining programs in tissues.
UCASpatial is introduced as an entropy-based ultra-precision deconvolution algorithm that improves detection of low-abundance and transcriptionally heterogeneous cell subpopulations in spatial transcriptomics. Applied to colorectal cancer and wound healing, it links chromosome 20q gain to T cell exclusion and disentangles pro-fibrotic versus regenerative cellular communities over time.
Impact: A high-resolution computational tool to decode fine-grained immune and stromal programs from spatial transcriptomics data.

SA2E: spatial-aware auto-encoder for cell type deconvolution of spatial transcriptomics data.
SA2E leverages a spatial-aware autoencoder to infer cell type proportions in spatial transcriptomics spots without relying solely on predefined marker genes. By jointly modeling spatial context and scRNA-seq–derived signatures, it addresses mixed-cell spots and improves robustness when marker information is incomplete.
Impact: An advanced deconvolution framework that boosts accuracy of cell-type mapping in complex spatial transcriptomics datasets.

Vascular invasion-associated gene expression is detectable in pre-surgical biopsies of stage I lung adenocarcinoma.
Bulk RNA-seq and spatial transcriptomics of stage I lung adenocarcinoma identify a robust gene signature linked to microscopic vascular invasion that extends beyond the invasive focus. A derived predictor generalizes across cohorts, remains stable under intratumor heterogeneity, and shows promising performance in limited pre-surgical biopsy material.
Impact: A spatially informed transcriptional signature with potential for preoperative risk stratification in early-stage lung cancer.

Single-Cell and Spatial Transcriptomic Profiling Reveals Epithelial Functional States and Fibroblast Phenotypes in Hormone Therapy-Naïve Localized Prostate Cancer.
Single-cell RNA-seq and spatial transcriptomics across malignant and adjacent-benign prostate cores reveal a malignant spectrum of epithelial states, including expanded club-like and dedifferentiated luminal populations. The study maps diverse stromal and fibroblast phenotypes, including a distinct perineural fibroblast population, and localizes cancer-associated fibroblast niches within the tumor microenvironment.
Impact: A detailed spatial and cellular blueprint of epithelial–stromal interactions in localized prostate cancer.

In Situ Needle-Free Injection of Multiretention Micelles for Melanoma Therapy with Multiomics Insights into Tumor Targeting and Immune Modulation.
This work presents a needle-free jet injection platform delivering paclitaxel-loaded multiretention micelles that combine physical, thermally driven, and pH-responsive mechanisms for prolonged intratumoral drug exposure. Multiomics, including single-cell and spatial transcriptomics, shows simultaneous direct tumor suppression and deep remodeling of the immune microenvironment, with enhanced leukocyte infiltration, ECM reprogramming, and reduced fibrosis.
Impact: A spatially profiled nanotherapy strategy that couples local chemotherapy delivery with immune microenvironment reconditioning in melanoma.

Chemokine-defined macrophage niches establish spatial organization of tumor immunity.
The study defines chemokine-driven niches that spatially organize distinct macrophage lineages within tumors, revealing a division of labor between tissue-resident CD206⁺ macrophages and recruited counterparts. These spatial macrophage programs shape local T cell function and anti-tumor immunity, highlighting how microanatomical positioning controls immune suppression versus activation.
Impact: A mechanistic map of chemokine-guided macrophage niches that structure spatial tumor-immune ecosystems.

💉 Immunology & Infectious Disease
CD8(+) T cells sustain vaccination-induced immunity against dissemination of contained tuberculosis in immunosuppressed hosts.
Using a mouse model of contained lymphatic Mycobacterium tuberculosis infection, the authors dissect how vaccination prevents reactivation under immunosuppression. They show that BCG and recombinant BCG can maintain control of latent infection and block dissemination even in the absence of CD4⁺ T cells, with CD8⁺ T cells playing a critical role in sustaining protective immunity.
Impact: Refines our understanding of T-cell–mediated protection against latent TB reactivation in immunocompromised settings.

Nanozyme Catalysis Restores Hair Follicle Integrity by Reversing Peroxisomal Collapse.
The authors identify peroxisomal dysfunction as a core metabolic defect in alopecia, demonstrating downregulated peroxisome pathways and oxidative stress–driven follicle degeneration in patient cells and Nudt7-deficient mice. Catalytic nanozymes mimicking peroxisomal catalase restore redox balance, boost PPARα-driven peroxisome biogenesis, and regenerate hair follicles, with spatial transcriptomics confirming activation of keratin and cytoskeletal regenerative programs.
Impact: Positions peroxisome-targeted nanozyme therapy as a metabolism-centric strategy for hair loss treatment, supported by spatial transcriptomic evidence.
