摘要：A sustained blood supply is critical for tumor growth, as it delivers the nutrients and oxygen required for development. Targeting of blood vessel formation via immunotherapies is an area of great importance. Knowing that certain embryonic genes, such as carcinoembryonic antigens (CEA) and oncofetal fibronectin, become reexpressed in malignant transformation, we hypothesized that a similar phenomenon holds true for tumor endothelial cells (TECs) as well. An approach for identification of highl...

摘要：An emerging concept for identification of different types of spin liquids [C. Broholm et al., Science 367, eaay0668 (2020)] is through the use of spontaneous spin noise [S. Chatterjee, J. F. Rodriguez-Nieva, E. Demler, Phys. Rev. B 99, 104425 (2019)]. Here, we develop spin noise spectroscopy for spin liquid studies by considering Ca10Cr7O28, a material hypothesized to be either a quantum or a spiral spin liquid (SSL). By enhancing techniques introduced for magnetic monopole noise studies [R. D...

摘要：West Nile virus (WNV) and Usutu virus (USUV) are closely related mosquito- borne neurotropic flaviviruses that share common transmission cycle and can infect humans. However, while human infections by WNV are widespread, infections by USUV are comparatively less frequent, less severe, and currently limited to Africa and Europe. To identify human host factors that contribute to the pathogenic signatures of these two flaviviruses, we carried out an arrayed expression screen of over 1,300 interfe...

摘要：Transmissibility of respiratory viruses is a complex viral trait that is intricately linked to tropism. Several highly transmissible viruses, including severe acute respiratory syndrome coronavirus 2 and Influenza viruses, specifically target multiciliated cells in the upper respiratory tract to facilitate efficient human- to- human transmission. In contrast, the zoonotic Middle East respiratory syndrome coronavirus (MERS- CoV) generally transmits poorly between humans, which is largely attrib...

摘要：Antibodies have the potential to target G protein-coupled receptors (GPCRs) with high receptor, cellular, and tissue selectivity; however, few antibody ligands for GPCRs exist. Here, we describe a generalizable selection method to enrich for GPCR ligands from a synthetic camelid antibody fragment (nanobody) library. Our strategy yielded multiple nanobody ligands for the angiotensin II type I receptor (AT1R), a prototypical GPCR and important drug target. We found that nanobodies readily act as...

摘要：Topologically associating domains (TADs) are sub-Megabase regions in vertebrate genomes with enriched intradomain interactions that restrict enhancer-promoter contacts across their boundaries. However, the mechanisms that separate TADs remain incompletely understood. Most boundaries between TADs contain CTCF binding sites (CBSs), which individually contribute to the blocking of Cohesin-mediated loop extrusion. Using genome-wide classification, here we show that the width of TAD boundaries form...

摘要：During cortical development, radial glial cells (neural stem cells) initially are neurogenic, generating intermediate progenitor cells that exclusively produce glutamatergic pyramidal neurons. Next, radial glial cells generate tripotential intermediate progenitor cells (Tri-IPCs) that give rise to cortical astrocytes and oligodendrocytes, and olfactory bulb interneurons. The molecular mechanisms underlying the transition from cortical neurogenesis to gliogenesis, and the subsequent fate determ...

摘要：Neural activity in sensory cortex is modulated by behavioral and cognitive factors, and this modulation is thought to contribute to the selection of specific sensory information needed to achieve behavioral goals. In contrast, more abstract behavioral variables that are independent of stimulus selection, such as stimulus-response mapping, are thought to be encoded by neurons outside of sensory cortex. We show that information about such mapping is robustly encoded in the responses of neurons i...

摘要：A key limitation of immune checkpoint inhibitors (ICI) therapy is their reduced efficacy toward cancers with a low tumor mutational burden (TMB). Since low- TMB tumors express fewer neoantigens, they are less responsive to ICI therapy like anti- PD- 1 and anti- CTLA- 4. In preclinical immunocompetent mouse models of low- TMB melanoma, we recently demonstrated that exposure to 6- thioguanine (6TG) significantly improved tumor control by increasing TMB and creating a proinflammatory tumor microe...
