Individuals with schizophrenia show reduced structural similarity in temporal, cingulate, and insular lobes, especially those with worse cognition and symptoms, affecting late maturing association areas with low metabolism and high neurotransmission.

Computational methods are used to predict which peptides or antigens are able to bind to MHC in order to activate T cell receptors in neoantigen-directed immunotherapies. Here the authors present an accurate transformer-based method to consider not only the peptide and MHC but also the source antigenic protein to predict peptides which bind to MHC molecules.

Large-scale single-cell sequencing of RNA and T cell receptors in samples from patients with cancer shows clonotypic expansion of effector-like T cells not only in tumour tissue but also in normal adjacent tissues and peripheral blood, which associates with clinical response to cancer immunotherapy.

ARID1A is an epigenetic regulator mutated in approximately 5% of non-hypermutated colorectal cancer tumors, however, its relationship with treatment response remains to be explored. Here, the authors suggest that ARID1A mutations may confer intrinsic and acquired resistance to cetuximab treatment.

Trace element ratios (strontium/calcium) in teeth of Pleistocene Homo erectus and fossil orangutans (Pongo sp.) reveal different dietary strategies and contrasting adaptations to seasonal food resources. H. erectus but not Pongo sp. was able to buffer against seasonal food oscillations by exploiting more varied food sources.

Large-scale analyses of the drug sensitivity of cancer cell lines have been previously reported to yield conflicting conclusions; this Analysis uses independently generated data to demonstrate that consistency can be achieved if key laboratory and data analysis practices are considered when future studies are undertaken.

In humans, TGFβ signalling is associated with lack of response to immunotherapy in immune-excluded tumours; in mouse models of this immune phenotype, robust tumour infiltration by T cells and tumour regression are observed only when checkpoint inhibition is combined with inhibition of TGFβ signalling.

Acquired resistance significantly limits the efficacy of cancer drug therapies. Here, the authors identify miR-371-3p as a suppressor of drug tolerance in cancer cell lines by its target gene PRDX6, which in turn regulates PLA2/PKCα signalling and ROS levels.

Evidence for the presence of Homo during the Middle Pleistocene is limited in continental Southeast Asia. Here, the authors report a hominin molar from Tam Ngu Hao 2 (Cobra Cave), dated to 164–131 kyr. They use morphological and paleoproteomic analysis to show that it likely belonged to a female Denisovan.

Single-cell and genetic tools are used to characterize the diversity of fibroblasts across healthy and perturbed tissues in mice and humans.

Fibroblastic reticular cells (FRCs) provide structural support and soluble factors necessary for proper lymph node organization and function. Turley and colleagues use scRNA-seq to identify a unique Gremlin1-expressing FRC subset that is found in T cell zones. Grem1⁺ FRCs support the survival of resident cDCs and are necessary to promote T cell immunity.

Competing financial interests. The majority of authors are employees of Genentech Inc. and/or hold stock in Roche.

The exclusion of T cells from solid tumours is a potentially important mechanism that regulates whether or not cancer patients respond well to checkpoint blocking immunotherapies. Here the authors identify immune phenotypes and mediators of T cell exclusion among ovarian cancer patient samples from the ICON7 phase III trial.

Treatment with demethylation agents can reactivate transposable elements. Here in glioblastoma, the authors also show that this is accompanied by de novo presentation of TE-derived peptides on MHC class I molecules.

A comprehensive analysis of RNA sequencing and single-nucleotide polymorphism (SNP) array data provides new insights into the biology of 675 human cancer cell lines

These authors performed a large-scale study in which they identified 2,576 somatic mutations across 1,507 coding genes from 441 breast, lung, ovarian and prostate cancer types and subtypes. The study provides an overview of the mutational spectra across major human cancers, implies an expanded role for Gα subunits in multiple cancer types and identifies several potential therapeutic targets.

Sekar Seshagiri and colleagues report exome, transcriptome and copy-number alteration data in small-cell lung cancer. The authors find SOX2 amplification in 27% of samples and also identify a recurrent RFL-MYCL1 fusion.

Exomes, transcriptomes and copy-number alterations in a sample of more than 70 primary human colonic tumours were analysed in an attempt to characterize the genomic landscape; in addition to finding alterations in genes associated with commonly mutated signalling pathways, recurrent gene fusions involving R-spondin family members were also found to occur in approximately 10% of colonic tumours, revealing a potential new therapeutic target.
