Tissue-resident macrophages (TRM) are important mediators of local immunity. Here the authors show that the deficiency or inhibition of a kinase, WNK1, unlinks macrophage colony-stimulating factor signaling and resulted macropinocytosis with the downstream, potentially IRF8-mediated genetic program to bias progenitor differentiation to neutrophil instead of TRM.

Using a 3-D neural platform, the authors show that a ubiquitin variant is sufficient to induce Alzheimer’s disease-like pathology in human neurons. Suppressing expression of this variant improved pathology in neurons carrying familial mutations.

The 20S particle is part of the 26S proteasome, but also exists as a free complex. Here, the authors outline signature activities of the 20S and combine chemical, structural, functional and proteomic assays to show that the 20S can degrade ubiquitin tags along with conjugated substrates.

UBA1-mutant macrophages exposed to inflammatory stimuli undergo aberrant apoptotic and necroptotic cell death mediated by CASP8 and RIPK3–MLKL, offering insights into the mechanisms underlying VEXAS syndrome.

This manuscript elucidates new mechanisms of mutagenesis in mycobacteria by implicating two translesion DNA polymerases in genome diversification, including creating the mutations that underlie all antibiotic resistance in these global pathogens.

The development of a first-in-class non-covalent small-molecule inhibitor of SARS-CoV-2 replication that targets the viral guanine-N7 methyltransferase NSP14 is reported.

In a prospective, regulatory-grade study of assistance to pathologists in MASH histology scoring, AIM-MASH-assisted reads by expert MASH pathologists were superior to unassisted reads and decreased inter-reader variability.

Human TNF is required for respiratory-burst-dependent immunity to Mycobacterium tuberculosis in macrophages but seems to be largely redundant physiologically.

The nuclear factor TOX is highly expressed in antigen-specific dysfunctional T cells in tumours and exhausted T cells during chronic viral infection and is a crucial regulator of the differentiation of tumour-specific T cells.

A meta-analysis of genome-wide association studies across different populations highlights new risk loci and provides a genetic risk score that can stratify prostate cancer risk across ancestries.

To kill target cells, cytotoxic T lymphocytes (CTLs) form an immune synapse (IS) to elicit cell death and the IS then dissolves to allow for CTL serial killing. Huse et al. find that IS dissolution occurs concomitantly with cytoskeletal contraction of apoptotic targets and this is both necessary and sufficient for CTL dissociation

Using data from MASH clinical trials, an AI model shows comparable performance with respect to individual pathologists in assessing histologic scoring for enrollment criteria and endpoint evaluation

Resistance to rifamycin antibiotics, which target bacterial RNA polymerases, is a growing problem. Here, the authors identify gene clusters from soil metagenomes encoding production of rifamycin analogues that are active against rifampicin-resistant bacteria through a distinct mechanism.

Dysregulated immune features in a patient with a homozygous loss-of-function mutation in PDCD1 suggest that IL-6, IL-23, STAT3 and RORγT might be potential targets for treatment of PD-1 blockade-induced autoimmunity.

A multi-ancestry genome-wide association study of prostate cancer performed in 156,319 cases and 788,443 controls identifies 187 novel risk variants associated with the disease. Genetic risk scores associated with overall risk, and risk of aggressive disease in men of African ancestry.

Antibiotic therapy can lead to pathogen clearance, but also to alterations in the gut microbiota and systemic immune responses. Here, the authors analyze data from patients with tuberculosis and healthy subjects to show that pathogen clearance and gut microbiota alterations are independently associated with antibiotic-induced changes of the inflammatory response of active tuberculosis.

Cryo-EM analysis reveals that the GrpE dimer of M. tuberculosis undergoes ratcheting motions when bound to an intact DnaK, thereby allosterically regulating DnaK’s nucleotide exchange and substrate release.

Genetic variants associated with susceptibility to pancreatic cancer have been identified using genome wide association studies (GWAS). Here, the authors combine data from over 9000 patients and perform a meta-analysis to identify five novel loci linked to pancreatic cancer.

Over one hundred loci have been identified to be associated with the familial risk of prostate cancer but the functional effects are poorly understood. Here the authors use single-nucleotide variant and epigentic data to show an underlying genetic architecture marked by histone modification.

C-terminal extended ubiquitin species, which have been associated with neurodegenerative disorders, were thought to inhibit proteasomes resulting in reduced protein clearance. Biochemical studies now provide evidence that these ubiquitin variants primarily block the activity of the deubiqutinating enzymes.

A high-resolution kidney cellular atlas of 51 main cell types, including rare and previously undescribed cell populations, represents a comprehensive benchmark of cellular states, neighbourhoods, outcome-associated signatures and publicly available interactive visualizations.

The RNA binding protein MUSASHI-2 (MSI2) is a potential therapeutic target for acute myeloid leukemia. Here the authors identify a small molecule inhibitor of MSI2 and characterize its effects in a murine leukemia model.

Ubiquitin (Ub) receptors are responsible for the recognition of ubiquitylated proteins. Here the authors describe the crystal structure of the ubiquitylated form of the Ub-receptor Rpn10, which suggest that ubiquitylation of Rpn10 promotes its dissociation from the proteasome.

Prostate cancer often does not progress to invasive disease and thus markers predicting the course of the disease progression are critical for optimal treatment choices. Here the authors show that variants at two genetic loci correlate with the aggressiveness of prostate cancer.

Cyclic GMP-AMP synthase (cGAS) is involved in the modulation of inflammatory responses. Here, the authors present small-molecule inhibitors of human cGAS, characterize their interaction with the protein, and show that the compounds are active in interferon-producing cells including primary human macrophages.

The long-held belief that bacteria rely solely on homologous recombination for the repair of double-strand breaks was recently overturned by evidence that many bacterial genera contain a system for non-homologous end joining (NHEJ). Biochemical, structural and genetic studies are beginning to define an NHEJ pathway that has distinctive features and enzymatic components.

NF-κB signalling involves the scaffold protein NEMO, which can be bound by the oncoprotein vFLIP to promote cell survival and oncogenic transformation. Here the authors rationally engineer a tertiary protein mimic of NEMO to disrupt the vFLIP-NEMO interaction to induce cell death.

Van Heijst and colleagues show that CD4⁺ T cells are programmed to downregulate TCR expression at the peak of clonal expansion in proportion to the strength of initial antigen recognition.

CEACAM1 functions as a novel heterophilic ligand for TIM-3 and is necessary for TIM-3-mediated tolerance, which has marked consequences for inflammation, infection and cancer.

This Review provides an overview of the main applications of single-port robotic surgery in urology, presenting emerging outcomes and discussing the transformative potential of this approach.

Analysis of a large, single-center cohort of patients with cancer who were infected with COVID-19 uncovers factors associated with disease severity and interactions with anti-cancer therapies

Using a small-molecule modulator of TORC2 signalling and a mechanosensitive probe, Riggi et al. reveal that decreased plasma membrane tension induces distinct PIP2-enriched domains that sequester and inactivate TORC2.

Intravesical BCG instillation is a longstanding therapy for bladder cancer, but its mode of action is still under investigation. This Review summarises the current understanding of the requirements for effective BCG therapy, and the putative roles of normal and malignant bladder cells, as well as the immune system, in the response to BCG.
