Class switch recombination (CSR) is a process by which B cells switch their immunoglobulin isotype and develop pathogen-eliminating antibodies. Here, the authors show that a protein kinase DYRK1A is required for protection from viral infection through the regulation of CSR and effective clonal expansion.
Topological lasers often suffer from low directionality, and/or complex design requirements hindering operation at small wavelengths. Here, by using a few monolayers of perovskite quantum dots, the authors demonstrate a lithography-free, vertical-emitting, single-mode laser emitting in the green.
Takano et al. show that heterologous booster by SARS-CoV-2 recombinant spike protein vaccine recalls a more sustained and broader anti-spike receptor-binding domain antibody response compared to homologous booster by mRNA vaccine.
How testis resident macrophages develop and influence tissue function is not fully understood. Here the authors use mouse lineage tracing methods to document the haematopoietic source, development and recruitment of early testicular macrophages, support of foetal testis differentiation, and interaction with, and promotion of steroidogenesis in, Leydig cells.
The cerebral cortex has ongoing electrical activities with rich and complex patterns in space and time. Here, the authors use optical voltage imaging in mice and computational methods, relating these complexities to different levels of wakefulness.
Previous demonstrations of electrically and optically detected magnetic resonance in OLED materials have established these systems as promising candidates for magnetic field sensing. Here the authors present an integrated OLED-based device for magnetic field imaging with sub-micron resolution.
It remains unclear how spontaneous Pancreatic Ductal Adenocarcinoma (PDAC) tumors escape Yap dependency. Here, the authors show that lineage plasticity promotes spontaneous relapse following YAP ablation and reveal key transcriptional drivers that overcome YAP addiction in PDAC.
Tropane alkaloids (TAs) are synthesized by some species in Solanaceae. Here, the authors assemble the genomes of two representative TAs producing species, show that gene loss shapes uneven distribution of TAs in Solanaceae, and identify a cytochrome P450 gene catalyzing N-demethylation of hyoscyamine to generate norhyoscyamine.
Polar functional groups can improve the polymer properties of polyolefins but also poison the metal catalyst used during the polymerization reaction. Here, the authors show that functionalized bimodal polyolefins in which the high-molecular-weight fraction bears few functional groups and possesses high mechanical and melt properties can be used to implement both polarity and processability
Carbon-heteroatom bond formation reactions are of high interest in synthetic organic chemistry. Here, the authors report the cobalt-catalyzed synthesis of tri- and tetrasubstituted alkenyl silanes and stannanes via C–O functionalization of vinyl acetates using silylzinc pivalate and stannylzinc chloride as the nucleophiles.
Dumpsites are hard to locate globally. Here the authors apply deep networks to satellite images to provide an effective and low-cost way to detect dumpsites with the new method saving more than 96.8% of the manual time with a strong sensitivity to dumpsites.
In this work, the authors show that photonic topological lattices with dissipative couplings could exhibit non-Abelian dynamics and geometric phases that are in sharp contrast to those arising in typical energy-conserving systems.
Treatment options in patients with recurrent endometrial carcinoma (EC) are limited and response rates to chemotherapy are poor. Here the authors report the results of a phase II trial of niraparib (PARP inhibitor) monotherapy or in combination with dostarlimab (anti-PD1) in recurrent EC.
The top-performing dry reforming photocatalysts in the literature rely on the use of precious metals. Here, enhanced photocatalytic dry reforming performance is reported through surface basicity modulation of a Ni/CeO2 photocatalyst, achieved by selectively phosphating the surface of a CeO2 nanorod support.
This work explains how the spatial structuring of populations, focusing on the globally dominant phytoplankton Prochlorococcus, can lead to erroneous statistical predictions for changes in plankton abundance as the ocean warms. Conflicting predictions of dynamical and statistical models for this biogeochemically critical species are resolved.
Cannabinoid CB2 receptor (CB2R) agonists are investigated as therapeutic agents in the clinic. Here, authors report the discovery of LEI-102, a CB2R agonist, used in conjunction with three other CBR ligands (APD371, HU308, and CP55,940) to investigate selective CB2R activation.
The brain-expressed receptor GPR10 is involved in energy homeostasis in mice. Here the authors identify rare loss of function variants in GPR10 in people with severe obesity and showed that one of these variants causes obesity when modelled in mice, suggesting that future studies could explore GPR10 as a potential target for weight-loss therapy.
Nanomedicine proofed to be efficient in cancer therapy but rapid clearance from blood circulation by reticuloendothelial system (RES) severely limits the antitumor efficacy. Here, the authors design a series of nanogels with distinctive stiffness and investigate how nanogel mechanical properties could be leveraged to overcome RES.
Antimicrobial peptides emerge as compounds that can alleviate the global health hazard of antimicrobial resistance. Here, the authors propose HydrAMP, an extended conditional variational autoencoder. HydrAMP generated antimicrobial peptides with high activity against bacteria, including multidrug-resistant species.
The pre-and postsynaptic communication is critical for faithful synaptic transmission and induction of synaptic plasticity. Here, the authors found that CaMKII functions at GABAergic neurons to recruit GABAARs by triggering anterograde signals.
