An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

LaccID, an engineered laccase, enables hydrogen-peroxide-free proximity labeling and electron microscopy (EM) in mammalian cells. Notably, LaccID is selectively active at the cell surface, enabling the mapping of the dynamic T cell–tumor surfaceome and its use as a genetically encodable EM tag, expanding the toolkit for cell-based imaging and proteomics.

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.

Whether multimorbidity accelerates brain Aβ deposition in humans remains largely unknown. Here, the authors demonstrate that higher self-reported multimorbidity burden predicts increased brain Aβ accumulation rates in the ADNI cohort.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

The Somatic Mosaicism across Human Tissues Network aims to create a reference catalogue of somatic mosaicism across different tissues and cells within individuals.

An initial draft of the human pangenome is presented and made publicly available by the Human Pangenome Reference Consortium; the draft contains 94 de novo haplotype assemblies from 47 ancestrally diverse individuals.

Human ALS/FTD patient iPSC-derived neurons are used to uncover mechanisms by which C9ORF72 mutations cause neurodegeneration.

The affected cellular populations during Alzheimer’s disease progression remain understudied. Here the authors use a cohort of 84 donors, quantitative neuropathology and multimodal datasets from the BRAIN Initiative. Their pseudoprogression analysis revealed two disease phases.

Modular synthetic G-protein-coupled receptors with nanobody-based ligand-recognition domains can be designed and used to programme transgene expression, real-time fluorescence or endogenous G-protein activation in response to soluble or cell-surface ligands, enabling control of diverse cellular behaviours.

A genome-wide association study including over 76,000 individuals with schizophrenia and over 243,000 control individuals identifies common variant associations at 287 genomic loci, and further fine-mapping analyses highlight the importance of genes involved in synaptic processes.

Combined patch clamp recording, biocytin staining and single-cell RNA-sequencing of human neurocortical neurons shows an expansion of glutamatergic neuron types relative to mouse that characterizes the greater complexity of the human neocortex.

Rhombohedral-stacked molybdenum disulfide with sliding ferroelectric behaviour can be used to create atomically thin ferroelectric transistors for computing-in-memory device applications.

The precise regulatory mechanisms controlling ciliary Hedgehog signaling remain incomplete. Here, the authors use ciliary proteomics to reveal that Numb facilitates the endocytosis of the receptor Ptch1 from the ciliary pocket, thereby enabling activation of Hedgehog signaling.

The light-sensitive LOV domain was engineered into the TurboID enzyme, creating ‘LOV-Turbo’. LOV-Turbo enables optogenetic control over proximity labeling, increasing the spatiotemporal precision of this technique.

Hypoxia has diverse effects on aquatic life. Wang et al.show that reproductive defects resulting from hypoxia are epigenetically heritable in Japanese rice fish, and that this intergenerational inheritance is accompanied by differential methylation and gene expression in sperm.

Comparisons within the human pangenome establish that homologous regions on short arms of heterologous human acrocentric chromosomes actively recombine, leading to the high rate of Robertsonian translocation breakpoints in these regions.

A transcriptome-wide association study identifies associations of genetically predicted gene expression with breast cancer risk. This analysis finds 48 candidate genes implicated in breast cancer susceptibility, including 14 at novel loci.

Constructing genome graphs directly from genome assemblies overcomes single-reference bias.

Rapid extracellular antigen profiling of a cohort of 194 individuals infected with SARS-CoV-2 uncovers diverse autoantibody responses that affect COVID-19 disease severity, progression and clinical and immunological characteristics.

Homologous recombination (HR) gene mutations are thought to be synthetic lethal with DNA polymerase theta (Polθ) inhibition. Here, the authors reveal that Polθ addiction is determined by the functional impact of gene mutations on DNA end resection activity.

A genome-wide association study of critically ill patients with COVID-19 identifies genetic signals that relate to important host antiviral defence mechanisms and mediators of inflammatory organ damage that may be targeted by repurposing drug treatments.

Plant NLR receptors trigger immune signaling following recognition of pathogen effectors. Here, Zhang et al. optimize a TurboID-based proximity labeling approach and show that it can be used to identify interacting partners of N, an NLR that confers resistance to Tobacco mosaic virus.

A study comparing the pattern of single-nucleotide variation between unique and duplicated regions of the human genome shows that mutation rate and interlocus gene conversion are elevated in duplicated regions.

Recent advances in fluorescent probe technology have improved spatial and temporal resolution, bringing us closer to the ideal of imaging individual cellular features in real time with molecular (1–5 nm) resolution. In parallel, the development of super-resolution imaging techniques has revolutionized fluorescence microscopy.

A region on chromosome 19p13 is associated with the risk of developing ovarian and breast cancer. Here, the authors genotyped SNPs in this region in thousands of breast and ovarian cancer patients and identified SNPs associated with three genes, which were analysed with functional studies.

Proximity labeling is used to map and discover proteins in specific subcellular compartments. Here the authors combine APEX-mediated proximity labeling with organic-aqueous phase separation to identify nuclear, nucleolar, and outer mitochondrial membrane RNA binding proteins.

The network of proteins secreted for interorgan communication is poorly understood. Here, the authors develop a method, based on protein labeling, to study cell-specific secretomes and interorgan protein trafficking, and demonstrate their approach in Drosophila and mouse models.

It is unclear why hemorrhagic myocardial infarctions (hMI) are destined for adverse outcomes. Here, the authors show that hMI drives fatty degeneration of infarct territories and contributes to adverse remodeling of the heart, which can be mitigated via timely depletion of iron within the hMI zone.

An optogenetic strategy enables selection of proteases with improved catalytic rates. The developed TEV protease variants are well suited for biotechnology applications, including FLARE assays with substantially improved temporal resolution.

A systematic review of evidence, across the key pillars of prevention, diagnosis, treatment and prognosis, outlines milestones that need to be met to enable the broad clinical implementation of precision medicine in diabetes care.
