The role of circular RNAs (circRNAs) in modulating gene expression in cancer remains to be investigated. Here, the authors perform whole transcriptome sequencing in 104 primary neuroblastomas and reveal the involvement of MYCN in regulating circRNAs.

Here the authors identify adenophages, a previously unknown macrophage population present in exocrine glands in mice and humans. These cells are dependent on ILC2-derived GM-CSF and support glandular homeostasis.

Westermann and colleagues define four subtypes of neuroblastoma based on super-enhancer profiles in primary patient samples, which could be linked to distinct clinical outcomes and cell identity characteristics.

Somatic evolutionary analysis of neuroblastoma, a pediatric tumor, proposes a common fetal time of origin. Notably, high-risk tumors exhibit early genomic instability and prolonged evolution, and this evolutionary duration predicts clinical outcomes.

Stoffers, Wolf et al. report that, in virus-mediated myocarditis, GPR15 deficiency delays the recruitment of T cells into cardiac tissue, which impairs viral elimination and leads to delayed but also prolonged inflammation and, thus, adverse cardiac outcomes.

Alternative lengthening of telomeres (ALT) is associated with a poor outcome in neuroblastoma. Here, the authors find that ALT is associated with mutated ATRX and/or reduced protein abundance, frequent telomeric repeat loci and heterochromatic telomeric chromatin.

Conjugating multiple molecules to proteins in a single step is crucial for advancing pharmaceutical and vaccine development. Here, the authors employ the Passerini 3-component reaction with isocyanoproteins to efficiently create multivalent protein conjugates, enabling simultaneous functionalization of the protein with biologically relevant molecules, such as carbohydrate antigens, lipids, and polymers.

Copy number alterations in stem cells impair neural crest differentiation and set the stage for neuroblastoma-like traits and tumours. This study hints at early tumourigenesis mechanisms and finds developmental gene signatures linked to prognosis.

A large-scale multi-omics analysis reports oncogenic alterations that drive medulloblastoma progression, rather than initiation, and the findings show how single-cell technologies can be used for early detection and diagnosis of medulloblastoma.

Alborzinia et al. report that MYCN-amplified neuroblastoma undergoes ferroptosis in the absence of intracellular cysteine, suggesting a combination of cysteine depletion and concomitant GPX4 inactivation as a potential therapeutic approach.

A single-cell transcriptomic analysis of neuroblastomas and healthy adrenal glands defines cell types and lineage trajectories during different developmental stages. Comparisons with the transcriptomes of neuroblastoma cells show that their transcriptomes most closely resemble those of developing neuroblasts of the adrenal gland.

Viral infections and exposure to inhaled allergens are linked to asthma onset, exacerbations and progression. Here, the authors used controlled experimental rhinovirus infection in patients with and without asthma, and further assessed in vitro the role of house dust mite allergen combined with rhinovirus and SARS-CoV-2 infection. They discovered that rhinovirus-induced activation of epithelial RIG-I inflammasome supresses antiviral immunity, promotes inflammation during asthma exacerbations and aggravates subsequent infection with SARS-CoV-2, particularly upon house dust mite exposure.

Interactions between germline variants and somatic mutations is a relatively unexplored topic in cancer. Here, in Ewing sarcoma, the authors show that binding of the oncogenic EWSR1-FLI1 fusion transcription factor to a polymorphic enhancer-like DNA element controls MYBL2, whose high expression correlates with prognosis.

ApoE is a direct checkpoint inhibitor of unresolvable inflammation in neurodegenerative and cardiovascular diseases

In cells that divide symmetrically, a meshwork of actin cables is shown to maintain the uniform distribution of mitochondria around the mitotic spindle. Actin clouds and comet tails are assembled dynamically to shuffle mitochondria locally and ensure the equal and random inheritance of these organelles by the two daughter cells.

Hereditary haemorrhagic telangiectasia (HTT) is caused by mutations in TGFβ/bone morphogenetic protein signalling genes. Here, Benzinouet al. show that variants of PTPN14, a gene within a mouse Tgfb1 modifier locus, associate with pulmonary arteriovenous malformation in HTT patients, shedding light on the molecular aetiology of this disease.

Here authors show that GDF15, a cytokine that is produced by cancer cells, prevents T cells from extravasation into the tumour microenvironment. Low availability of T cells in GDF-15-expressing tumours thus precludes effective immune therapy.

Extracellular vesicles can carry immunoregulatory cytokines such as TGF-β. Here the authors use CD11b-deficient mice and macrophages to show that such vesicles carrying TGF-β are produced in response to Candida albicans infections and can limit the proinflammatory response partly via a positive feedback on TGF-β production by endothelial cells.

The mechanism by which adenosine monophosphate modulates dynein ATPase-mediated ciliary and flagellar beating remains obscure. Here the authors identify an axonemal module including cilia and flagella associated protein 45 that supports adenine nucleotide homeostasis and underlies a human ciliopathy

During mitosis, complementary actin-based mechanisms ensure equal and random distributions of mitochondria among daughter cells following symmetrical cell division.

In gene regulation, diversification at the transcriptome 3′end is linked to differentiation and dedifferentiation. Here, the authors discover extensive transcriptome 3′end-alterations in neuroblastoma, regulated by PCF11, and provide an interactive data repository of transcriptome-wide alternative polyadenylation.

Troponin is a widely used biomarker in patients with cardiac disease. In this Review, Westermann et al. describe the development of high-sensitivity assays for troponin, and their practical use in clinical diagnosis of acute myocardial infarction. Elevated concentrations of troponin in myocardial injury and chronic cardiac disease are also discussed.

Analyses of genomes from 914 children, adolescents, and young adults provide a comprehensive resource of genomic alterations across a spectrum of common childhood cancers.

Using dual RNA-seq technology to profile RNA expression simultaneously in the bacterial pathogen Salmonella and its host during infection reveals molecular phenotypes of small noncoding RNAs in the infection process.

Reduced generation of multiple motile cilia (RGMC) is a rare mucociliary clearance disorder, characterized by chronic airway disease. Here, the authors identify mutations in the Multicilin gene, MCIDAS, and suggest that these mutations cause RGMC through disruption of multiciliated cell differentiation.

Permafrost thaw poses a serious threat to the sustainable development of Arctic communities. Here the authors show that most fundamental Arctic infrastructure and population will be at high hazard risk, even if the Paris Agreement target is achieved.

Schwann cells (SCs) can acquire a repair phenotype following nerve injury. Here, the authors show that stromal SCs in ganglioneuromas express nerve-repair genes. Importantly, neuroblastoma cells respond to repair-related SCs increasing neuronal differentiation and reducing proliferation via EGFL8.

In this placebo-controlled trial, 10/13 malaria naïve subjects immunized with a simplified regimen of chemoattenuated P. falciparum sporozoites, PfSPZ-CVac, show sterile protection from heterologous malaria challenge. Immunization was well tolerated and induced high levels of anti-PfCSP antibodies.

Vicinity of small bodies might be dangerous to the spacecrafts and to their instrumentation. Here the authors show the operational environment of asteroid Bennu, validate its photometric phase function and demonstrate the accelerating rotational rate due to YORP effect using the data acquired during the approach phase of OSIRIS-REx mission.

Protein kinase A (PKA) is a key mediator of cyclic AMP signalling. Here, Eccles et al. show that ARHGAP36 antagonizes PKA by acting as a kinase inhibitor and targeting the catalytic subunit for endolysosomal degradation, thus reducing sensitivity of cells to cAMP and promoting Hedgehog signalling.

Individuals with the disease hereditary hemorrhagic telangiectasia have vascular defects that lead to frequent hemorrhages. Franck Lebrin et al. now show that thalidomide, tested as a therapy in a small set of individuals with this disease, lowers the frequency of hemorrhaging and the need for blood transfusions. The authors tie the antihemorrhagic effects of thalidomide to its ability to promote blood vessel maturation through effects on PDGF-B expression by endothelial cells and on pericyte cell proliferation (pages 370–372).
