The paper introduces Orthrus, a specialized RNA foundation model designed to predict the properties and functions of mature transcripts. Unlike traditional genomic models that rely on text-based learning, Orthrus utilizes a biologically inspired contrastive learning objective that leverages data from alternative splicing and evolutionary orthologs across hundreds of species. This approach allows t...去小宇宙查看完整单集简介

This research utilizes single-cell RNA sequencing and spatial transcriptomics to map the developmental journey of cerebellar granule neurons and their relationship to medulloblastoma tumorigenesis. By analyzing thousands of murine cells, the authors identify four distinct cellular states—ranging from proliferating progenitors to mature neurons—and pinpoint their exact physical locations within the...去小宇宙查看完整单集简介

Recent research reveals that the membrane-associated periodic skeleton (MPS), a structure previously thought to be stable, undergoes continuous disassembly and reassembly in neurons. Using live-cell super-resolution imaging, scientists discovered that this skeletal network regularly remodels itself even without external triggers. This dynamic process is controlled by calcium signaling, which activ...去小宇宙查看完整单集简介

This research investigates the three-dimensional organization of the genome across diverse cell types in the mouse cerebral cortex. By integrating DNA and RNA imaging techniques, the study demonstrates that nuclear architecture and chromatin structure vary significantly between neurons and non-neuronal cells. These structural differences, including nuclear volume and higher- order chromosome foldi...去小宇宙查看完整单集简介

This research identifies a specific group of inhibitory neurons in the ventral medial preoptic area (VMPO) of the hypothalamus that acts as a central hub for managing sickness symptoms. These neurons are activated by immune signals like prostaglandins and cytokines released from nearby non-neuronal cells, such as astrocytes and ependymal cells, during infection. When these VMPOLPS neurons are trig...去小宇宙查看完整单集简介
