The research identifies a novel subset of cancer-associated fibroblasts (CAFs), termed PTGER3+ lipoCAFs, which are induced by chemotherapy in bladder cancer. Unlike typical stromal cells that shield tumors, these fibroblasts undergo metabolic reprogramming to enhance lipid oxidation, specifically using the enzyme CYP1B1 to convert arachidonic acid into the metabolite 11-HETE. This secreted molecule acts as a natural inhibitor of PTEN within CD8+ T cells, triggering the AKT/mTOR signaling pathway to boost immune activation and tumor-killing efficiency. Clinical data demonstrates that patients with a higher abundance of these lipoCAFs experience significantly better chemotherapy responses and prolonged survival. Furthermore, the study suggests that supplementing treatment with 11-HETE or its precursors can synergistically improve the efficacy of both chemotherapy and immunotherapy. These findings reveal a critical stromal mechanism that transforms the tumor microenvironment into an immune-promoting landscape during cancer treatment.

The paper details a scientific study on the Andes virus (ANDV), a dangerous hantavirus, and the development of high-resolution structural models of its glycoprotein assembly. Researchers utilized virus-like particles (VLPs) and cryo-electron microscopy to reveal the near-atomic architecture of the viral surface, identifying how glycoprotein tetramers organize into a lattice. These structures clarify how the virus senses acidic environments to trigger membrane fusion and how specific neutralizing antibodies, such as ADI-65534, bind to the virus. Furthermore, the study explores a self-amplifying RNA vaccine candidate that successfully elicits immune responses in mice. By defining these molecular interfaces, the research establishes a critical foundation for creating structure-based vaccines and therapeutics against hantaviruses.

This paper examines a longitudinal single-cell atlas that identifies the biological drivers behind the success or failure of BCMA-targeted CAR T cell therapy in multiple myeloma patients. The research highlights that long-term remission is not determined by cell dose, but rather by specific T cell phenotypes, particularly the presence of cytotoxic CD4+ T cells and memory-biased states. It also redefines cell exhaustion, noting that dysfunctional T cells often show mitochondrial issues and specific markers like TIGIT rather than traditional exhaustion signals. Furthermore, the study identifies soluble BCMA as a potential biomarker for tracking both treatment response and inflammatory toxicities. These findings suggest that future improvements in manufacturing and patient monitoring could lead to more precise and effective immunotherapies. Overall, the text provides a detailed roadmap for optimizing cellular engineering to achieve durable clinical outcomes and better manage side effects.

This review examines tumor-associated macrophages (TAMs), which are diverse immune cells capable of either driving cancer growth or eliminating malignant cells. While traditional therapies attempted to broadly deplete these cells, modern strategies focus on reprogramming or effectorizing them to restore their natural anti-tumor functions. Scientists are now targeting "don’t-eat-me" signals to enhance phagocytosis and using genetic engineering, such as CAR-M cells, to create precision immune responses. The research also reveals that tumors influence myeloid progenitors systemically in the bone marrow, necessitating therapies that address cancer as a whole-body disease. By utilizing single-cell omics and spatial mapping, researchers aim to move beyond simple categorization to achieve sophisticated control over macrophage biology. Ultimately, these next-generation approaches seek to transform TAMs into frontline effectors that can eradicate tumors independently or in coordination with T cells.

The CUBIC Organ/Body Atlas is a groundbreaking biological resource providing three-dimensional, single-cell resolution maps of major mouse organs and the entire neonatal body. To create this atlas, researchers optimized tissue clearing protocols and developed a high-speed imaging system called exMOVIE, which overcomes traditional trade-offs between working distance and image resolution. This technology allows for the precise detection and enumeration of hundreds of millions of individual cells while maintaining their original spatial orientation. The study demonstrates the atlas's utility by tracking cellular dynamics during kidney development and quantifying tissue changes in models of acute lung injury and cancer metastasis. By offering a standardized framework for cellomics, these sources enable a systems-level understanding of how cellular organization shifts across different physiological and pathological states. The researchers have made these comprehensive datasets and interactive web tools publicly available to support broader scientific investigation into mammalian biology.

The paper introduces HoloTea, a novel computational framework designed to generate 3D volumetric tissue gene expression profiles from serial histology images. While traditional methods often analyze tissue slices in isolation, this model ensures anatomical continuity by retrieving morphologically similar data from adjacent sections to inform its predictions. The system utilizes a scalable flow-matching architecture and biology-aligned ZINB priors to accurately capture the complex nature of transcript count data. By leveraging global attention mechanisms, it remains efficient enough to process massive datasets that would otherwise overwhelm standard hardware. Experimental results across breast cancer and embryo datasets demonstrate that HoloTea significantly improves reconstruction accuracy over existing 2D and 3D baselines. Ultimately, this tool offers a cost-effective way to build virtual 3D tissues, facilitating a deeper understanding of cellular organization and disease.

This research article investigates the functional organization of the human brain by identifying shared connectivity patterns across the isocortex, cerebellum, and hippocampus. Using advanced gradient mapping on large neuroimaging datasets, the authors discovered that these seemingly distinct structures operate under a common systems-level framework. They identified two primary functional gradients that correspond across all three regions, suggesting a highly coordinated architecture for processing information. The study proposes that this structural alignment supports predictive processing, a computational theory where the brain constantly generates and updates internal models of the world. By demonstrating these robust, replicable links, the authors provide a new integrative foundation for understanding how different brain parts work together to regulate the body and mind.

This research article introduces 18F-flurimedrimer (18F-FMD), a novel PET imaging tracer designed to non-invasively track innate immune cell activation in the central nervous system. Using a mouse model of Multiple Sclerosis (MS), the study demonstrates that this radiolabeled dendrimer can detect neuroinflammation at both presymptomatic and acute stages of the disease. The technology provides a significant advantage over traditional MRI by specifically identifying activated myeloid cells, such as microglia and macrophages, which drive disease progression. Furthermore, the authors show that 18F-FMD effectively monitors therapeutic responses to treatments like fingolimod and a new CSF1R-targeting dendranib. These results suggest that 18F-FMD could become a vital clinical tool for personalized medicine and real-time monitoring of inflammatory brain disorders. The study concludes that this tracer successfully bridges a gap in molecular imaging, offering a high-resolution window into the cellular dynamics of autoimmune neurodegeneration.
