Here, using cryo-EM and biochemistry, the authors delineate how the XPD helicase unorthodoxly uses its Arch domain to separate double-stranded DNA upon approaching a DNA lesion, promoting our understanding of NER bubble formation and damage verification.

The link between amyloid and tau proteins with Alzheimer’s disease progression remains unclear. Here, the authors propose HDACs I downregulation as an element linking the deleterious effects of brain proteinopathies with disease progression.

A multi-ancestry analysis in large cohorts of patients with type 2 diabetes (T2D) identified 12 disease genetic clusters with distinct cardiometabolic trait associations, including two lipodystrophy-related clusters that could provide insights on the increased T2D susceptibility in East Asian ancestries at a given body mass index level.

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

Controlled particle acceleration in plasmas requires precise measurements of the excited wakefield. Here the authors report and demonstrate a high-resolution method to measure the effective longitudinal electric field of a beam-driven plasma-wakefield accelerator.

The role of IgG glycosylation in the immune response has been studied, but less is known about IgM glycosylation. Here the authors characterize glycosylation of SARS-CoV-2 spike specific IgM and show that it correlates with COVID-19 severity and affects complement deposition.

Here, Heitmann et al. report results from a Phase I/II trial evaluating CoVac-1, a peptide-based T-cell activator, in patients with B-cell deficiency, demonstrating potent induction of SARS-CoV-2-specific T-cell responses along with a favorable safety profile.

Solid organ transplant recipients are at increased risk of infectious disease and have unique molecular pathophysiology. Here the authors use host-microbe profiling to assess SARS-CoV-2 infection and immunity in solid organ transplant recipients, showing enhanced viral abundance, impaired clearance, and increased expression of innate immunity genes.

The DNAJB1-PRKACA fusion transcript is the oncogenic driver in fibrolamellar hepatocellular carcinoma, a lethal disease with limited therapeutic options. Here, the authors identify the DNAJB1-PRKACA protein as a source for immunogenic neoepitopes and a potential target of T cell-based immunotherapy.

This paper describes the ‘4DN Data Portal’ that hosts data generated by the 4D Nucleome network, including Hi-C and other chromatin conformation capture assays, as well as various sequencing-based and imaging-based assays. Raw data have been uniformly processed to increase comparability and the portal is implemented with visualization tools to browse the data without download.

MS-based immunopeptidomics provides direct evidence for HLA peptide-antigen presentation, which is indispensable for therapeutic use. Here the authors present an ion mobility MS-based immunopeptidome workflow, largely expand benign reference databases and enables next generation tumor antigen discovery.

In this work, authors assess airway microbiome dynamics to show bacterial pneumonia in critically ill COVID-19 patients is significantly associated with death, corticosteroid treatment, disruption of the lung microbiome and a distinct pulmonary host response.

A high-throughput nanoscale 3D microscopy technique, combining imaging flow cytometry with a point-spread function, allows 3D localization measurements in live flowing cells.

This study by Zielinski et al. used cryo-EM to compare Aβ fibril structures from mouse models to those from patients with Alzheimer’s disease. It revealed that tg-APP_ArcSwe mice exhibit fibrils resembling those predominantly found in sporadic Alzheimer’s disease cases.

The phase 3 GENESIS trial reports the superiority of the novel CXCR4 inhibitor motixafortide with G-CSF in mobilizing hematopoietic progenitor cells for autologous stem cell transplantation in multiple myeloma.

Summary for general audience: We used carbon stable isotope data from an Antarctic ice core to evaluate which mechanisms caused changes in atmospheric carbon dioxide 74-59 thousand years ago, including a ~40 ppm decrease at the beginning of the last ice age.

A dual genetic strategy enables the labelling and in vivo imaging of native long-term haematopoietic stem cells in the mouse calvarial bone marrow.

FLS2 is the well-known plasma membrane receptor for flg22, a specific region of bacterial flagellin. But Solanaceae can also detect flagellin through another epitope, flgII-28, thanks to the novel receptor-like kinase FLS3 now identified in tomato.

Post-acute sequelae of SARS-CoV-2 (PASC) is still not well understood. Here the authors provide patient reported outcomes from 590 hospitalized COVID-19 patients and show association of PASC with higher respiratory SARS-CoV-2 load and circulating antibody titers, and in some an elevation in circulating fibroblast growth factor 21.

Spatial profiling and single-cell RNA sequencing are used to map the spatial distribution of the microbiota within human tumours, revealing how intratumoral microbial communities contribute to tumour heterogeneity and cancer progression.

Passegué and colleagues reveal that pro-inflammatory IL-1 accelerates cell division and induces PU.1-mediated differentiation of HSCs into myeloid cells, whereas chronic IL-1 exposure compromises HSC function.

Binding of the small-molecule inhibitor CGI1746 to Bruton's tyrosine kinase (Btk), a therapeutic target for rheumatoid arthritis, induces an inactive Btk conformation. Application of this specific chemical probe reveals two Btk signaling pathways involved in inflammatory arthritis.

Now, the encapsulation of perovskite solar cells with self-healing polymers is shown to significantly reduce the risk of lead leakage from hail impact under a variety of weather conditions.

Here, a combination of genetic studies of gene expression, cross-species network analysis and genome-wide association studies has been used to identify gene networks and the loci underlying their regulation in rats. The results show that an inflammatory network driven by interferon regulatory factor 7 contributes to susceptibility to type 1 diabetes, and implicate the innate viral-response pathway and macrophages in the aetiology of this disease.
