Chan et al. generate a high-resolution spatiotemporal atlas of healing hearts and reveal cellular networks of lesion repair, including macrophage–fibroblast interactions that control late-stage fibrosis and immune niches that induce cardiomyocyte de-differentiation.

Genomic analyses applied to 14 childhood- and adult-onset psychiatric disorders identifies five underlying genomic factors that explain the majority of the genetic variance of the individual disorders.

Polygenic scores for body mass index and obesity constructed using data from 5 million people with different ancestries were associated with distinct weight gain trajectories from early childhood to adulthood.

ACKR3 is a critical regulator of platelet-mediated thrombosis and organ injury following ischemia/reperfusion. Platelet ACKR3 surface expression is independently associated with all-cause mortality in patients with cardiovascular diseases.

A rationally designed peptide agonist that targets three key hormone receptors reduces obesity and its complications in a manner superior to other agonists.

A large genome-wide association study of more than 5 million individuals reveals that 12,111 single-nucleotide polymorphisms account for nearly all the heritability of height attributable to common genetic variants.

Exome sequencing within a structured diagnostic process for rare diseases in Germany shows how facial image analysis and machine learning can guide variant prioritization and uncover many ultrarare diseases.

Liver-resident natural killer (NK) cells sustain the dormancy of disseminated breast cancer cells, and a decrease in NK cells and increase in activated hepatic stellate cells is associated with the formation of liver metastases.

Genome-wide association analyses of 41,917 bipolar disorder cases and 371,549 controls of European ancestry provide new insights into the etiology of this disorder and identify novel therapeutic leads and potential opportunities for drug repurposing.

Medulloblastoma in children is a difficult cancer to treat and the immune response to this tumour is not fully understood. Here the authors characterise and validate T cell epitopes from these cancers using an immunopeptidomics approach, comparing different molecular subtypes.

Human brain structure changes throughout the lifespan. Brouwer et al. identified genetic variants that affect rates of brain growth and atrophy. The genes are linked to early brain development and neurodegeneration and suggest involvement of metabolic processes.

Genome-wide association analyses of two oral glucose tolerance test-derived measures of postprandial insulin resistance discover ten new loci. Functional characterization identifies nine candidate genes implicated in the regulation of GLUT4.

In a GWAS study of 32,438 adults, the authors discovered five novel loci for intracranial volume and confirmed two known signals. Variants for intracranial volume were also related to childhood and adult cognitive function and to Parkinson's disease, and enriched near genes involved in growth pathways, including PI3K-AKT signaling.

Genome-wide analysis identifies variants associated with the volume of seven different subcortical brain regions defined by magnetic resonance imaging. Implicated genes are involved in neurodevelopmental and synaptic signaling pathways.

The hippocampus in mammalian brain varies in size across individuals. Here, Hibar and colleagues perform a genome-wide association meta-analysis to find six genetic loci with significant association to hippocampus volume.

Niche crosstalk with Haematopoietic cells underlies normal haematopoiesis and myeloid disorders. Here the authors report a Stabilin2-Cre driver mouse with Cre-activity restricted to bone marrow sinusoidal endothelial cells, and that Stabilin2-Cre driven overactivation of b-catenin leads to erythroid differentiation defects and anaemia.

The authors defined a roadmap for investigating the genetic covariance between structural or functional brain phenotypes and risk for psychiatric disorders. Their proof-of-concept study using the largest available common variant data sets for schizophrenia and volumes of several (mainly subcortical) brain structures did not find evidence of genetic overlap.

Genome-wide analysis identifies 30 loci associated with bipolar disorder, allowing for comparisons of shared genes and pathways with other psychiatric disorders, including schizophrenia and depression.

Bispecific antibodies can bind to two distinct targets though the fusion of two different Fv regions. In this study, the authors develop DutaFabs that present two separated and independent antigen binding sites within the same Fv region, giving rise to bispecific Fab fragments.

Streptococcus pneumoniae is a common cause of lower respiratory tract infection. Here, Klabunde et al. present a transcriptomic, metabolomic and proteomic characterisation of the bronchial epithelial cell response to infection and show that NAD⁺ has a role in controlling bacterial replication.

Chordomas are rare bone tumors with limited therapeutic options. Here, the authors identify molecular alterations associated with defective homologous recombination DNA repair in advanced chordomas and report prolonged response in a patient treated with a PARP inhibitor, which later acquired resistance due to a newly gained PARP1 mutation.

Individual variation in fMRI-derived brain networks is reproduced in a model using only the smoothness (autocorrelation) of the fMRI time series. Smoothness has implication for aging and can be causally manipulated by psychedelic serotonergic drugs.

The identification of molecular biomarkers in cancer of unknown primary site (CUP) cases may enable the improvement of prognosis in these patients. Here, the authors integrate whole genome/exome, transcriptome and methylome data in 70 CUP patients, recommend therapies based on their analysis and report clinical outcome data.

Activated protein C (APC) is a plasma serine protease with antithrombotic and cytoprotective functions. Here, the authors develop a monoclonal antibody that specifically inhibits APC’s anticoagulant function without compromising its cytoprotective function, and shows efficacy in animal models.

A systematic review with a Burden of Proof meta-analysis reporting a nonlinear relationship between ambient fine particulate matter and dementia across 28 longitudinal cohort studies, highlighting the potential impact of air pollution on brain aging.

Induction of cardiac contractility, although desirable for restoring heart function, often has long-term detrimental effects. From studies on RKIP, an upstream regulator of β-adrenergic receptor signaling, Schmid et al. show that cardiac contractility in mice can be increased in a well-tolerated manner through the balanced activation of the β1 and β2 subtypes of the adrenergic receptor.

This study shows that Aβ from transgenic host tissue is able to enter and deposit within wild-type grafts via microglia, thus identifying microglia as carriers of Aβ deposition into previously unaffected brain tissue.

Cells undergoing normal or premature ageing show several global defects in chromatin. Components of the NURD chromatin remodelling complex, such as histone chaperones, are now shown to be lost in cells from patients with a premature aging disorder and in normally aged cells. Conversely, depleting NURD subunits and Hdac1 recapitulates the chromatin defects seen in aged cells.

Sarah von Spiczak, Holger Lerche and colleagues identify mutations in GRIN2A that cause idiopathic focal epilepsy with rolandic spikes.

Genome-wide association studies are used to identify common genetic variants that affect the structure of selected subcortical regions of the human brain; their identification provides insight into the causes of variability in brain development and may help to determine mechanisms of neuropsychiatric dysfunction.
