The study reveals how this la...

This research article describes a novel "TCR turbocharging" pipeline designed to enhance the effectiveness of T cell receptors used in cancer immunotherapy. Scientists focused on a specific receptor, TCR156, which targets a prostate cancer antigen but naturally lacks the strength to eliminate tumors due to immune tolerance. By engineering specialized interactions called catch bonds, which strength...

The paper details the creation of the Human Endoderm-derived Organoid Cell Atlas (HEOCA), a massive integrated dataset comprising nearly one million single-cell transcriptomes. Researchers synthesized data from 55 publications and nine different tissue types to harmonize cell annotations and establish a benchmark for organoid fidelity. By comparing lab-grown tissues to primary fetal and adult refe...

This research identifies vascular tissue-resident macrophages (VRMs) as essential protectors against abdominal aortic aneurysm (AAA) progression. These specific cells, located in the outer layer of the artery, secrete a protein called Sparcl1 to maintain vascular health. When Sparcl1 is absent, the growth factor FGF2 triggers abnormal lymphatic vessel growth and the formation of tertiary lymphoid...

This review examines the neuroimmunometabolic co-evolution in cancer, detailing how the nervous system coordinates with immune and metabolic processes to influence tumor progression. At the tumor microenvironment (TME) scale, the authors explain how peripheral neurons—including sympathetic, parasympathetic, and sensory types—reprogram local metabolism and suppress anti-tumor immunity. Expanding to...

This article introduces GASTON, an unsupervised deep learning algorithm designed to analyze complex spatial transcriptomics data. By calculating a metric called isodepth, the tool creates a topographic map of tissue slices that functions similarly to elevation on a geographical map.
