This research presents a novel high-throughput yeast display platform designed to engineer fast-acting covalent protein drugs that overcome the limitations of rapid systemic clearance. By integrating site-specific chemical crosslinkers with precise protein mutations, the authors successfully developed IB101, a potent PD-L1 antagonist, and IB201, a covalent IL-18 agonist. These engineered proteins ...去小宇宙查看完整单集简介

The researchers introduced TranscriptFormer, a family of generative foundation models designed to analyze single-cell transcriptomic data across 1.53 billion years of evolution. By training on up to 112 million cells from 12 diverse species, the model learns to represent cellular states and gene relationships in a species-agnostic embedding space. It achieves state-of-the-art performance in classi...去小宇宙查看完整单集简介

The research explores how the chemical 6-hydroxydopamine (6-OHDA), traditionally used to destroy sympathetic nerves, actually suppresses breast cancer growth through immune system activation rather than nerve loss. By comparing various denervation methods, scientists discovered that only 6-OHDA inhibits tumors by triggering cancer cells to produce interferon-beta (IFN-β) via the cGAS pathway. This...去小宇宙查看完整单集简介

This research identifies a critical nerve-cancer crosstalk within the peritumoral microenvironment of pancreatic ductal adenocarcinoma (PDAC). The study reveals that CD4+ T cells release interleukin-22, which prompts nearby acinar cells to secrete Reg proteins. These proteins then bind to the EXTL3 receptor on both tumor cells and neurons, simultaneously driving cancer invasiveness and nerve growt...去小宇宙查看完整单集简介

This research identifies a novel mechanism where the mechanical forces generated by the beating cilia of ependymal cells are essential for keeping adult neural stem cells (NSCs) in a dormant, or quiescent, state. By utilizing an innovative method involving magnetic beads and electromagnetic fields to temporarily halt ciliary movement, the study demonstrates that even a brief interruption of these ...去小宇宙查看完整单集简介

The study explores how Notch2 signaling manages the structural organization of lymph nodes by directing the development of specialized fibroblastic reticular cells. Researchers identified a unique circuit where homeostatic mature dendritic cells provide continuous Jagged1 signals to maintain a specific population of Ccl19-high fibroblasts in the central T cell zone. This interaction creates distin...去小宇宙查看完整单集简介

The research examines how palmitic acid (PA) facilitates the spread of triple-negative breast cancer to the lungs by modifying the local environment before tumor cells even arrive. The study identifies that pulmonary endothelial cells serve as a primary source of PA, which triggers neutrophils to release the protein lipocalin-2 (LCN2) via the TLR4-NF-κB signaling pathway. This process degrades vas...去小宇宙查看完整单集简介

This study presents a comprehensive spatiotemporal transcriptomic atlas of chronic colitis by integrating longitudinal data from two distinct mouse models. Researchers utilized bulk, single-cell, and spatial RNA sequencing to map how the immune, epithelial, and stromal compartments are rewired during disease progression. The findings reveal a conserved inflammatory signature between murine models ...去小宇宙查看完整单集简介

The research identifies the mevalonate (MVA) pathway and its derivative, GGPP, as critical regulators of T follicular helper (Tfh) cell differentiation and function. Scientists discovered that the enzyme GGTase II uses GGPP to modify RAB35 proteins, a process essential for recycling the CXCR5 receptor to the cell surface so Tfh cells can interact with B cells. This metabolic axis is driven by T ce...去小宇宙查看完整单集简介

This research describes the development of pleiotropic chimeric antigen receptor-monocytes (pCAR-Mos), an innovative cell therapy designed to treat myocardial infarction and prevent heart failure. By engineering monocytes to target fibroblast activation protein (FAP) and secrete the regenerative protein Agrin, researchers created a dual-action treatment that simultaneously clears pathological fibr...去小宇宙查看完整单集简介
