Aerobic methanotrophic bacteria are considered strict aerobes but are often highly abundant in hypoxic or anoxic environments. Here, the authors show that acidophilic methanotrophs can respire nitrous oxide and grow anaerobically on diverse non-methane substrates, including methanol, C-C substrates, and hydrogen.
Although the function of Toll-like receptor 9 (TLR9) in immunity and inflammation is well-established, its role in obesity is less well-studied. In this study, the authors demonstrate that TLR9 deficiency in B cells is associated with obesity in mice and results in altered frequencies of T and B lymphocyte subsets and gut microbiome dysbiosis.
Interface engineering by local polarization is becoming increasingly important for tunable electronics. Here, authors demonstrate an electric pulse-tuned piezotronic effect in Ag/HfO2/n-ZnO junction, enabling reversible and accurate regulation of barrier height and piezotronic modification range.
Multi-Inflammatory Syndrome in Children (MIS-C) is a severe post-infectious presentation related to SARS-CoV-2 infection. Here authors used multi-omics approaches to characterise MIS-C cases and found increased CD95 and IL-18 signalling accompanying the expansion of TCR Vβ 21.3+ T cells.
Here the authors investigate the interactions between genetic perturbations and segregating loci on a genome scale in yeast using barcoded CRISPRi. Strains’ responses to perturbations are shaped by perturbation-locus interactions that cannot be measured by examining perturbations or natural variation alone.
Targeted drug delivery in vivo is a complex challenge, and understanding the characteristics that define the behavior of delivery vehicles in vivo is vital for advancing delivery vehicle design. Here the authors use a library of polymeric delivery vehicles and high-throughput tools to study the structure-function relationships guiding the physiological fate of nanomedicines.
Control of correlated excitonic states is a key goal of modern optoelectronic physics. Here, the authors demonstrate filling- and field-tunable exciton valley-pseudospin orders in a moiré heterostructure.
Waning immunity and the emergence of the SARS-CoV-2 Omicron lineage led to reduced vaccine effectiveness and required vaccine updates. Here, the authors assess how different priming regimens affect the immunogenicity of BA.1 and BA.5 bivalent boosters.
The molecular basis underlying infection infection-mediated lung pathology is not fully revealed. Here the authors report that SPARCL1 expressed in pulmonary capillary endothelial cells contributes to immune pathology in mouse model via pro-inflammatory macrophage induction, while circulating SPARCL1 levels corelate with COVID-19 lethality.
Naked mole-rats are long-lived rodents known to be resistant to the development of cancer, yet their immune system remains poorly explored. Here, the authors identify natural killer-like effector γδ T cells that express a dominant γδ T cell receptor and may serve a role in tumour immunosurveillance.
Here, the authors introduce Photoacoustic Tomography with Temporal Encoding Reconstruction (PATTERN) - a high-speed, non-destructive photoacoustic brain imaging technique that constructs 3D fluorescent maps of the brain and improves upon some of the limitations associated with traditional whole-brain optical imaging techniques.
The relevance of mitochondrial cysteine metabolism to ferroptosis is unknown. Here, Ward et al. show that mitochondrial Fe-S cluster synthesis persists under cysteine limitation via the catabolism of glutathione and at the expense of cell viability.
Extreme magnetoresistance is characterized by a large and non-saturating magnetoresistance. Typically, it is observed in materials with compensated bandstructures, however, here, Christensen et al demonstrate a large and non-saturating magnetoresistance in a γAl2O3/SrTiO3 heterostructure, which is related to disorder, rather than the materials bandstructure.
The mechanisms driving B cell differentiation into resident bone marrow plasma cells (BMPC) remain unclear. Here the authors use single cell sequencing and BMPC phenotyping to infer developmental pathways and regulation by IL-21 in germinal centres to promote maintenance of BMPC after vaccination in humans.
The peroxisomal β-oxidation enzyme ACOX1 increases in liver with obesity, but the physiological significance is unclear. Here, the authors show that liver-specific knockout of Acox1 leads to accumulation of omega-3 VLCFAs that promote metabolic health through activation of GPR120 in adipose tissue.
Tumor-resident intracellular microbiota (TRIM) could be a potential target for anticancer treatment. Here the authors report Au@Ag2Se nano-assemblies enabling bacterial killing, tumor inhibition and immune regulation in tumor microenvironment.
Here, Ge et al use cryo-electron microscopy to resolve the structure of the bacteriophage lambda tail in complex with its LamB receptor from Shigella sonnei and shed light on the conformational changes that the phage tail fiber undergoes in response to binding.
The neuronal mechanism of how the prefrontal cortex exerts top-down influence on the cingulo-striatal network during decision-making in depressive states is not fully understood. Here authors showed that negative bias in decision-making can be artificially induced via stimulating such neural network and they observed diminished top-down influences correlating with the depressive state.
The viral polymerase complex is crucial for both genome replication and transcription in non-segmented negative-strand RNA viruses. Here, the authors link varying structures of polymerase complexes with their dual functions and propose a sliding model for them to advance along the RNA templates.
