T cell responses can be generated to either pathogen infection or from priming with a vaccine. Here the authors compare T cell generation, phenotype and single cell transcriptome of participants vaccinated with a mpox vaccine or infected with the virus showing that the virus induced T cells showed more effective function and phenotype.

Sinclair et al. explore the contribution of chronic inflammation to cardiovascular symptoms associated with post-acute sequelae of SARS-CoV-2 infection (PASC-CVS). The authors identify trace levels of inflammatory cytokines in individuals with PASC-CVS that impair the function of cardiomyocytes derived from induced pluripotent stem cells.

The molecular characteristics of myocarditis associated with immune checkpoint inhibitors are described and potential biomarkers of onset and severity are identified.

Viral pathogen load in cancer genomes is estimated through analysis of sequencing data from 2,656 tumors across 35 cancer types using multiple pathogen-detection pipelines, identifying viruses in 382 genomic and 68 transcriptome datasets.

A genome-wide association study including over 76,000 individuals with schizophrenia and over 243,000 control individuals identifies common variant associations at 287 genomic loci, and further fine-mapping analyses highlight the importance of genes involved in synaptic processes.

Openshaw and colleagues find myeloid inflammation and complement activation signatures in patients with long COVID who were previously hospitalized.

Waldenström macroglobulinemia (WM)/lymphoplasmacytic lymphoma (LPL) is a non-Hodgkin-type B cell lymphoma. Here, the authors identify two risk loci for WM/LPL in a two-stage GWAS involving a family-oversampling approach and provide evidence for a functional role of the non-coding SNP rs116446171.

Immune surveillance has been proposed to eliminate transformed cells and thereby limit tumor formation. Axel Kallies and colleagues now report that spontaneous B cell lymphoma development in Blimp1-deficient or Bcl6-overexpressing mice is accelerated by T cell deficiency and identify the Fas-Fas ligand pathway as a crucial mediator of T cell control of lymphoma growth.

Aarno Palotie and colleagues present results of a large genome-wide association study of migraine. They identified significant associations at 38 distinct loci and found enrichment for genes expressed in vascular and smooth muscle tissues.

Manipulation of the host cell actin cytoskeleton is a common feature for many viruses. In this Review, Taylor, Koyuncu and Enquist describe how the interaction of viral proteins with the actin cytoskeleton alters the structure and function of this cytoskeleton, allowing viral infections to initiate, persist and spread.

Integration of GWAS and single-cell transcriptomic data from the entire nervous system systematically identifies cell types underlying brain complex traits and provides insights into the etiology of Parkinson’s disease.

Gilean McVean and colleagues report the results of a large-scale clinical genome sequencing project spanning a broad spectrum of disorders. They identify factors influencing successful genetic diagnosis and highlight the challenges of interpreting findings for genetically heterogeneous disorders.

Wheat stripe (yellow) rust is a devastating disease posing a threat to global production. Here, the authors report the cloning of a wheat stripe rust resistance gene encoding a protein with a NAM domain and a ZnF-BED domain using a strategy called sequencing trait-associated mutations (STAM).

The Cancer Genome Atlas presents an integrative genome-wide analysis of genetic alterations in 279 head and neck squamous cell carcinomas (HNSCCs), which are classified by human papillomavirus (HPV) status; alterations in EGFR, FGFR, PIK3CA and cyclin-dependent kinases are shown to represent candidate targets for therapeutic intervention in most HNSCCs.

It is unclear how often genetic mosaicism of chromosome X arises. Here, the authors examine women with cancer and cancer-free controls and show that X chromosome mosaicism occurs more frequently than on autosomes, especially on the inactive X chromosome, but is not linked to non-haematologic cancer risk

Luis Pérez-Jurado, Stephen Chanock and colleagues detect clonal chromosomal abnormalities in peripheral blood or buccal samples from individuals in the general population. They show that the frequency of such events increases with age and is associated with elevated risk of developing subsequent hematological cancers.

Stripe rust is a serious threat to wheat production. Here, the authors reveal that the resistance gene, only present in the wheat progenitor Aegilops tauschii and its derived synthetic wheat, encodes a nucleotide oligomerization domain-like receptor and confers resistance in common wheat and barley.

Richard Houlston and colleagues identify four new susceptibility loci for colorectal cancer through a meta-analysis of genome-wide association data, followed by replication testing in a large collection of independent samples. The study brings to ten the number of confirmed loci harboring low-penetrance risk alleles for this common malignancy.

The dominant male-sterile geneMs2 has facilitated the release of hundreds of wheat-breeding lines and cultivars in China. Here Ni et al. describe the cloning of the Ms2 gene, which appears as an orphan gene in the Triticinae, and show that Ms2 can be used to confer male sterility in wheat, barley and Brachypodium.

Fifty-five percent of individuals vaccinated with an attenuated Plasmodium falciparum sporozoite vaccine remained without parasitemia after controlled human malaria infection one year later; immune correlate analysis in humans and non-human primates suggest a role for liver-resident T cells.

Maria Teresa Landi and colleagues identify a rare missense variant in POT1 shared by five melanoma-prone families from Italy and associated with increased telomere length and telomere fragility. They also identify additional familial melanoma cases with rare missense variants in POT1 and find a significant excess of rare exonic POT1 variants in melanoma cases compared to controls, implicating POT1 variants in melanoma susceptibility.

The UK IBD Genetics Consortium and the Wellcome Trust Case Control Consortium 2 report results of a genome-wide association study of ulcerative colitis. They identify three new loci associated with the disease, including the HNF4A region on 20q13.

Richard O'Connell and colleagues report the genomes and transcriptomes of two Colletotrichum plant fungal pathogens. C. higginsianum infects Arabidopsis thaliana, and C. graminicola infects maize (Zea mays); comparative genomics in both species lead to molecular insights into the transition from biotrophic to necrotrophic life stages.

Detailed clinical and virologic characteristics of the first 12 individuals with COVID-19 in the United States from the US Centers for Disease Control and Prevention.
