Here, the authors perform cross-trait analyses of respiratory and cardiometabolic diseases, rheumatoid arthritis, and smoking and identify negative genetic correlations between respiratory and cardiometabolic diseases in individuals of East Asian ancestry, in opposition from the positive association in European ancestry individuals.

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.

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.

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.

Authors present results from a national surveillance in Japan that found MRSA strains causing bloodstream infections are predominantly from three clonal lineages. They also identified the emergence of highest 30-day-mortality MRSA clone ST764-SCCmecII and traced its evolutionary path.

Neutrophils are early mediators for inflammation, but their functions in autoimmunity is still unclear. By using single cell analyses to compare patients with microscopic polyangiitis (MPA) and controls, here the authors find increased IFN-II-related neutrophils induced by IFN-γ and TNF signaling as a relapse risk marker for small vessel vasculitis.

After transplantation into the brain of patients with Parkinson’s disease, allogeneic dopaminergic progenitors derived from induced pluripotent stem cells survived, produced dopamine and did not form tumours, therefore suggesting safety and potential clinical benefits for Parkinson’s disease.

A genome-wide association study meta-analysis combined with multiomics data of osteoarthritis identifies 700 effector genes as well as biological processes with a convergent involvement of multiple effector genes; 10% of these genes express the target of approved drugs.

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 superconducting gap structure of FeSe remains a debated issue. Here, Hashimoto et al. report momentum dependence of the gap in single- and multi-___domain regions of orthorhombic FeSe crystals, revealing an unusual node lifting of the gap structure in multi-___domain regions.

A newly discovered control system regulates the eliminations of meiosis-specific transcripts during mitosis, but allows their expression in meiosis.

The collective intermolecular dynamics of protein and water molecules, which overlap in subterahertz frequencies, are relevant for protein function expressions. Here the authors develop highly sensitive dielectric measurements, revealing that protein hydration is nonthermally accelerated by sub-terahertz irradiation.

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 dynamic assembly and disassembly of atoms and molecules is challenging to characterize in real time, with atomic resolution and elemental identification. Here, the authors report direct observation of more than twenty homo and hetero-metallic compounds, including labile Ag-Cu dimers and Au-Ag-Cu trimers.

Sphingosine 1-phosphate receptor 1 (S1PR1) is crucial for lymphocyte trafficking and a target in inflammatory diseases. Here, authors discover KSI6666, a competitive S1PR1 antagonist that suppresses inflammation through pseudoirreversible inhibition.

Using biobank data from over 250,000 participants, the authors present a detailed picture of regional and individual variation in the tripartite ancestral structure of modern Japanese populations and demonstrate its impact on elevated body mass index.

Oncogenic Ras is known to activate the Raf–MEK–ERK phosphorylation cascade to promote mitogenic signalling. Ras also inhibits the downregulation of MAPK pathway activity by preventing the MEKK1 SUMO E3 ligase from sumoylating and inactivating MEK.

The Ca²⁺-permeable channel TRPM2 stimulates monocytes to produce chemokines in response to reactive oxygen species, and channel inhibition attenuates inflammatory disease in mice. TRPM2 could be a new target for treating inflammatory diseases.

Structure and functions of the tip of migratory neurons remain elusive. Here, the authors show that the PTPσ-expressing growth cone senses extracellular matrix changes and drives neuronal migration in the injured brain, leading to the functional recovery.

Vaccines with broad and long-lasting protection against variants of concern are still limited. Here, the authors report a self-amplifying RNA (saRNA) vaccine expressing a membrane-anchored SARS-CoV-2 Spike RBD and show that it elicits broad, durable and protective immunity in small animal models and NHPs.

Amyloid fibrils of β2-microglobulin (β2m) can cause dialysis-related amyloidosis. Here, the authors show that a decrease in serum albumin levels in long-term dialysis deteriorates the inhibitory effects of serum milieux on supersaturation-limited amyloid formation of β2m, suggesting that macromolecular crowding protects the onset of amyloidosis.

Mammalian genomes are scattered with repetitive sequences, but their biology remains largely elusive. Here, the authors show that transcription can initiate from short tandem repetitive sequences, and that genetic variants linked to human diseases are preferentially found at repeats with high transcription initiation level.

Cell division and expansion are carefully coordinated during organ growth. Here, the authors show that the SCL28 and SMOS1 transcription factors interact to regulate cyclin-dependent kinase inhibitors and promote cell size increase over division in Arabidopsis.

The structure of human prostaglandin E receptor EP4 in complex with antagonist ONO-AE3-208 and a functional antibody reveals a ligand-binding site at the interface of the lipid bilayer that is unique among GPCRs.

Plant colonization of land is an important evolutionary event. Here, the authors sequence the genome of a filamentous terrestrial alga and, through a comparative analysis with related algae and land plant species, provide insight into how aquatic algae adapted to terrestrial environments.
