Segal and colleagues identify a population of immature neutrophils as having regenerative properties on injured neurons and being capable of inducing axon regeneration. These findings suggest potential strategies for restoring lost neurological functions in central nervous system disorders.

Comprehensive genomic profiling of human H3K27M mutant diffuse midline gliomas, combining single-cell RNA sequencing and ATAC sequencing with bulk ChIP sequencing and other data, proposes distinct oligodendrocyte populations as potential cells of origin.

In this study, Kagan et al. highlight the relevance of adequate cardiolipin homeostasis by offering mechanistic insight into the pathogenesis of Barth syndrome. The study shows how altered accumulation of mono-lyso-cardiolipin, one of the derivatives of the mitochondrial lipid cardiolipin, forms an anomalous peroxidase complex with cytochrome c, thus leading to increased oxidation of polyunsaturated phospholipids.

A study of the evolution of the SARS-CoV-2 virus in England between September 2020 and June 2021 finds that interventions capable of containing previous variants were insufficient to stop the more transmissible Alpha and Delta variants.

Ependymoma is a type of neural tumour that arises throughout the central nervous system. Using comparative transcriptomics in mouse and human tumours, these authors home in on mutations that are specific to individual tumour subgroups. In doing so, they generate the first mouse model of ependymoma and demonstrate the power of interspecific genomic comparisons to interrogate cancer subgroups.

A single-cell transcriptomic atlas from embryonal pons and forebrain provides insights into the developmental origins of pediatric brain tumors. The study identifies impaired differentiation of specific neural progenitors as a common mechanism underlying these cancers.

Mutations in the methyl-CpG-binding protein 2 (MeCP2) gene cause Rett syndrome, a neurodevelopmental disorder with features of autism. Multiple mouse models of MeCP2 have been generated, but show only a subset of the symptoms of Rett syndrome. These authors find that mice with selective deletion of MeCP2 in GABA-mediated neurons show not only impaired GABA-mediated function, but capitulate multiple key features of Rett, further suggesting a role of inhibitory function in neuropsychiatric disease.

Chronic infection with SARS-CoV-2 leads to the emergence of viral variants that show reduced susceptibility to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma.

Sera from vaccinated individuals and some monoclonal antibodies show a modest reduction in neutralizing activity against the B.1.1.7 variant of SARS-CoV-2; but the E484K substitution leads to a considerable loss of neutralizing activity.

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 structural basis of the interactions between Rubisco and its intrinsically disordered linker protein provides insight into phase separation within the algal pyrenoid, an organelle responsible for around a third of global CO₂ fixation.

A large-scale genetic analysis of type 1 diabetes identifies new susceptibility variants, highlights potential regulatory mechanisms and provides genetic support for therapeutic targets for immune intervention.

Plasma levels of liver enzymes provide insights into hepatic function and related diseases. Here, the authors perform a genome-wide association study on three liver enzymes, identifying genetic variants associated with their plasma concentration as well as links to metabolic and cardiovascular diseases.

Genome-wide association meta-analyses among 1.4 million individuals identify 318 new risk loci for type 2 diabetes and provide insight into the contribution of these risk variants to diabetes-related vascular outcomes.

Post-international travel quarantine has been widely implemented to mitigate SARS-CoV-2 transmission, but the impacts of such policies are unclear. Here, the authors used linked genomic and contact tracing data to assess the impacts of a 14-day quarantine on return to England in summer 2020.

In this study, Aggarwal and colleagues perform prospective sequencing of SARS-CoV-2 isolates derived from asymptomatic student screening and symptomatic testing of students and staff at the University of Cambridge. They identify important factors that contributed to within university transmission and onward spread into the wider community.

Holtzman and colleagues identify PARP9-DTX3L as an E3 ubiquitin ligase complex that interacts with STAT1 to modify chromatin accessibility for expression in interferon-stimulated genes and to target viral proteases for degradation.

Smoke is a solid. Whether from cigarettes, cooking fires or other sources, it is comprised of tiny particles that injure the lung and can lead to lung cancer and chronic obstructive pulmonary disorder, characterized by laborious breathing. Steven D. Shapiro and his colleagues take a look at imaging data in people suggesting that these two conditions have more in common mechanistically than was previously thought. Both diseases seem to stem in part from the ability of inhaled particles to trigger inflammation, a process examined by Robert M. Senior and his colleagues.

A computational approach to generate reference-free protein families from the sequence space in metagenomes reveals an enormously diverse functional space.

STAAR is a powerful rare variant association test that incorporates variant functional categories and complementary functional annotations using a dynamic weighting scheme based on annotation principal components. STAAR accounts for population structure and relatedness and is scalable for analyzing large whole-genome sequencing studies.

The Omicron variant evades vaccine-induced neutralization but also fails to form syncytia, shows reduced replication in human lung cells and preferentially uses a TMPRSS2-independent cell entry pathway, which may contribute to enhanced replication in cells of the upper airway. Altered fusion and cell entry characteristics are linked to distinct regions of the Omicron spike protein.
