A single-cell multiomic immune cell atlas from 235 Japanese, including patients with COVID-19 and healthy individuals, linked with host genetics including germline and somatic mutation, plasma proteomics and metagenomics data reveals that immune cells are dynamically regulated in a cell state-dependent manner.

Analysis of the blood DNA virome in patients with COVID-19 and autoimmune disease associates endogenous HHV-6 (eHHV-6) and high anellovirus load with increased disease risk, most notably for systemic lupus erythematosus. eHHV-6 carriers show a distinct immune response.

A genome-wide association study highlights a variant in DOCK2, which is common in East Asian populations but rare in Europeans, as a host genetic risk factor for severe COVID-19.

Genetic mechanisms influencing COVID-19 susceptibility are not well understood. Here, the authors analyzed whole blood RNA-seq data of 465 Japanese individuals with COVID-19, highlighting thousands of fine-mapped variants affecting expression and splicing of genes, as well as the presence of COVID-19 severity-interaction eQTLs.

Tanaka and colleagues perform a comprehensive multi-omic characterization of peritoneal metastasis of gastric cancer to define molecular subtypes and actionable therapeutic targets.

Uncultured open-ocean Asgard archaea can harvest light energy using rhodopsins and diverse hydroxylated carotenoid antennas.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Peripheral blood mononuclear cells from 73 Japanese patients with coronavirus disease 2019 (COVID-19) and 75 healthy controls were analyzed using single-cell transcriptomics. Combining these data with genotyping data highlights the interplay between host genetics and the immune response in modulating disease severity.

Bando et al. perform a phase II trial of atezolizumab monotherapy following platinum-based definitive chemoradiotherapy in patients with unresectable locally advanced esophageal squamous cell carcinoma and report a complete response rate of 42%.

The transcription factor GATA3 is enhanced in innate lymphoid type 2 cells (ILC2). Here the authors characterize the super enhancer regions of GATA3 and show that these enhancers are required to drive GATA3 expression and stage specific ILC2 development.

Using new phagocytosis reporter mice and 3D ultrastructural characterization, Morizawa et al. show that motor learning induces synaptic engulfment by BG, which contributes to synaptic pruning during the improvement of motor adaptation.

The molecular heterogeneity of KMT2A-rearranged infant acute lymphoblastic leukemia (ALL) remains poorly characterised. Here, the authors perform multi-omics analysis for 84 ALL patients and suggest 5 distinct subgroups for risk stratification and personalised treatment.’

Mammalian genomes are scattered with repetitive sequences, but their biology remains largely elusive. Here, the authors show that transcription can initiate from short tandem repetitive sequences, and that genetic variants linked to human diseases are preferentially found at repeats with high transcription initiation level.

Uterine adenomyosis often co-occurs with endometriosis or leiomyoma, but little is known about its molecular underpinnings. Here, the authors show that KRAS mutations are frequent in this disease, which might reduce sensitivity to progestin treatment via epigenetic silencing of the progesterone receptor.

Somatic mutations in ASXL1 lead to clonal hematopoiesis, and Sato et al. elucidate the molecular mechanisms by which mutated ASXL1 in hematopoietic cells drives atherosclerosis in mice.

Cellular reprogramming and cancer development share properties. Here, the authors examine the impact of in vivo reprogramming on Kras-induced cancer and show reprogramming-mediated repression of somatic cell enhancers in conjunction with Kras mutation results in rapid PDAC development.

The mechanisms by which in vivo expression of the Yamanaka transcription factors (OSKM) renders somatic cells permissive for differentiation remain unclear. Here, the authors show that in vivo reprogramming using OSKM generates germ cell tumors and drives acquisition of totipotency-like features in somatic cells through DMRT1.

Multiplexed imaging to study cellular pathways can be hampered by lack of antibody specificity, especially when assessing signal activation. Here, the authors present Precise Emission Canceling Antibodies (PECAbs), which enable high-specificity sequential imaging and the study of signaling pathways.

Animals may approach normally aversive stimuli such as an air puff when in a non-enriched environment. Here the authors show that dopamine release in the ventral lateral striatum was reduced by aversive stimulation, but was increased when it was actively sought.

Light energy transfer from abundant hydroxylated carotenoids to the retinal moiety of widespread light-driven proton pumps is detected.

KRAS mutations, particularly KRAS(G12D), are prevalent in various cancers, yet effective treatments remain elusive. Here, the authors introduce ASP3082, a pioneering KRAS(G12D)-selective degrader, demonstrating its potent tumor regression capabilities in xenograft models.

Leukemic stem cells (LSCs) in chronic myeloid leukemia are resistant to imatinib and therefore are a cause of relapse. The authors show that IRAK1/4-NF-κB-PD-L1 signaling is critical to mediate imatinib resistance in LSCs and that combining imatinib with blocking this signalling pathway can eliminate LSCs.

S. Matsuo et al. report tunneling spectroscopy measurements on a device consisting of two Josephson junctions (JJ) sharing a single superconducting electrode. In isolation, each JJ would host an Andreev bound state (ABS). In their coherently-coupled JJs, the authors report the formation of an Andreev molecule due to hybridization of the two ABSs.

MDM2 is frequently overexpressed in acute myeloid leukaemia leading to p53 inactivation. Here, the authors are demonstrating that an inhibitor of p53-MDM2 interaction, DS-5272, induce in vivo tumour regression through immune response regulation.

Angle-resolved photoemission spectroscopy is used to track the evolution of the electronic band structure of TaSe₃ across a strain-driven topological phase transition.
