Sjögren’s disease (SjD) can be split into different subtypes and these may have different molecular profiles. Here the authors compare anti-SSA and anti-centromere autoantibody positive SjD and show using spatial transcriptomics and TCR and BCR sequencing that different molecular signatures are found between the subtypes of SjD.

Mohri et al. show that, in response to genotoxic stress, melanocyte stem cells undergo senescence-associated differentiation, causing their depletion and protecting them against melanomagenesis. This process is suppressed by carcinogens.

A single-cell multiomic immune cell atlas from 235 Japanese, including patients with COVID-19 and healthy individuals, linked with host genetics including germline and somatic mutation, plasma proteomics and metagenomics data reveals that immune cells are dynamically regulated in a cell state-dependent manner.

How the Drosophila lymph gland hemocytes develop and are regulated at a single-cell level is unclear. Here, the authors use single-cell RNA sequencing to show heterogeneity of developing hemocytes in the lymph gland and how they react to wasp infestation, and compare hemocytes from two independent origins.

A superconducting diode that has zero resistance in only one direction is realized in an artificially engineered superlattice without inversion symmetry, enabling directional charge transport without energy loss.

In a large cohort with a 23-month median follow-up of the CIRCULATE-Japan GALAXY observational study, ctDNA-based detection of molecular residual disease was predictive of survival outcomes and benefit of adjuvant chemotherapy in patients with resectable colorectal cancer.

Genetic mechanisms influencing COVID-19 susceptibility are not well understood. Here, the authors analyzed whole blood RNA-seq data of 465 Japanese individuals with COVID-19, highlighting thousands of fine-mapped variants affecting expression and splicing of genes, as well as the presence of COVID-19 severity-interaction eQTLs.

A genome-wide association study highlights a variant in DOCK2, which is common in East Asian populations but rare in Europeans, as a host genetic risk factor for severe COVID-19.

Analysis of the blood DNA virome in patients with COVID-19 and autoimmune disease associates endogenous HHV-6 (eHHV-6) and high anellovirus load with increased disease risk, most notably for systemic lupus erythematosus. eHHV-6 carriers show a distinct immune response.

Spin–orbit-driven effects are of great interest for spintronic applications but the underlying mechanisms are challenging to probe. Here, the authors develop a sensitive spin–orbit torque magnetometer to quantify the interface and bulk contributions to the spin–orbit torques in magnetic bilayers.

Graphene has a centrosymmetric crystal symmetry, which prohibits second-order effects in transport experiments. Yet, giant second-order nonlinear transports can emerge in graphene moiré superlattices at zero magnetic field, originating from the skew scattering of chiral Bloch electrons in the superlattice and giving rise to both longitudinal and transverse nonlinear conductivities under time-reversal symmetry.

Boron analogues of cyclic hydrocarbons have yet to be observed. Here, the authors isolate and characterize bicyclic borane molecule B14H26, advancing our understanding of borane chemistry.

An array of optical traps formed in a nanophotonic waveguide can trap and manipulate biomolecular nanoparticles in three dimensions.

Iga et al. perform single-cell RNA sequencing and identify a distinct bone marrow endothelial cell subtype that contributes to the acquisition of bone strength and offers a distinct haematopoietic stem cell niche.

Peripheral blood mononuclear cells from 73 Japanese patients with coronavirus disease 2019 (COVID-19) and 75 healthy controls were analyzed using single-cell transcriptomics. Combining these data with genotyping data highlights the interplay between host genetics and the immune response in modulating disease severity.

The FANTOM4 study identified transcriptional start sites active during proliferation arrest and differentiation of the human monocytic cell line THP-1. Systematic knockdown of 52 transcription factors provide support for their model in which a complex transcriptional network regulates the differentiation process.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Here, the authors inversely associate Blautia wexlerae with obesity and type 2 diabetes mellitus in humans and further show that administration of B. wexlerae to mice decrease both high-fat diet–induced obesity and diabetes via modulating gut microbial metabolism.

Understanding antibody-antigen interactions is important to deepen the understanding of immunology. Here, the authors report on the application of DNA origami structures for the controlled presentation of antigens to study antibody binding behaviours at room temperature.

Although seismic anisotropy in the upper mantle is generally attributed to the crystal-preferred orientation of olivine, the strong trench-parallel anisotropy observed in several subduction systems is difficult to explain in terms of olivine anisotropy. Using high-pressure deformation experiments, it is now shown that the crystal-preferred orientation of serpentine, the main hydrous mineral in the upper mantle, can produce the strong trench-parallel seismic anisotropy observed in such subduction systems.

Photonic methods can be greatly improved by metal nanoparticles, but biological targets such as cells prevent spatial control of particles, excluding key regions of interest. Here, the authors show laser light can control nanoparticle growth locations in the cell, and probe intracellular molecules.

Previous genome-wide association studies have identified risk loci for pancreatic cancer but were centered on individuals of European ancestry. Here the authors identify GP2 gene variants associated with pancreatic cancer susceptibility in populations of East Asian ancestry.

Long-read sequencing identifies a GGC repeat expansion in NOTCH2NLC that is associated with neuronal intranuclear inclusion disease, a progressive neurodegenerative disorder. The expansion results in abnormal anti-sense transcripts that could contribute to disease pathogenesis.

Using more than 100 independent iPSC lines derived from patients with Alzheimer’s disease, the authors discovered loci associated with the neuronal production of amyloid β and confirmed their influence using RNA interference.

Diabetes is a major cause of kidney disease. Here Kikuchi et al. show that phenol sulfate, a gut microbiota-derived metabolite, is increased in diabetic kidney disease and contributes to the pathology by promoting kidney injury, suggesting phenyl sulfate could be used a marker and therapeutic target for the treatment of diabetic kidney disease.

The endosomal sorting complex required for transport-III (ESCRT-III) has been implicated in the packaging of HIV and HSV-1 viruses in the cytoplasm. Here the authors show that ESCRT-III proteins are required for the transport of HSV-1 nucleocapsids from nucleoplasm to cytosol through the nuclear envelope and confirm that the same mechanism is also used for the nucleocytoplasmic transport of RNP in Drosophila cells.
