An in-depth analysis of tissue biopsies from patients with multiple myeloma and CAR T cell therapy-associated immune-related adverse events (CirAEs) after treatment with commercial BCMA-targeted CAR T cell therapy shows that CD4⁺ CAR T cells mediate off-tumor toxicities and that high CD4:CD8 ratio at apheresis, robust early CAR T cell expansion, ICANS and ciltacabtagene autoleuce treatment are independently associated with the development of CirAEs.

The mechanisms controlling reproductive hormone secretion are unclear. Here the authors show that noradrenergic inputs to kisspeptin neurons are able to control pulsatile hormone release in a sex- and gonadal steroid-dependent manner.

Region-specific increases in hippocampal activity have been reported in schizophrenia patients, yet there are little known about how these circuit levels changes modulate behavioral deficits. Here authors found that that over-expression of the a5 subunit of the GABAA receptor increased tonic GABA currents and normalized aberrant pyramidal cell activity in the ventral hippocampus which had distinct disease symptom outcomes depending on the pathway targeted

How the complex interplay between multiple nutrients within the microenvironment dictates potential sites of metastatic cancer growth is explored.

Shroom3 genetic variants increase Shroom3 levels and promote kidney fibrosis but reduce proteinuria, complicating Shroom3 targeting for precision medicine. Here, the authors show increased fibrosis mediated by Shroom3–Rock signaling and blocking this interaction genetically or with new compounds reduces tubular Rock activation and fibrosis.

Moral-Sanz, Fernández-Carrasco and colleagues identify senolytic properties of sea anemone-derived pore-forming toxins, with selectivity mediated by senescence-associated lipid profiles. An optimized senotoxin improves the efficacy of chemotherapy in mouse models.

Here, the authors develop an analytical framework, scFOCAL, to predict the sensitivity of glioblastoma cell subpopulations to therapies based on reversal of disease transcriptional signatures to identify synergistic therapeutic combinations.

Inherited mitochondrial DNA mutations can result in diverse clinical phenotypes. Here, the authors characterise a heteroplasmic tRNA^Ala mutation (m.5019A>G) in mice and demonstrate that macrophages carrying this mutation display altered function and metabolism in vitro, along with increased type I IFN release following LPS challenge in vivo.

Pathology-oriented multiplexing (PathoPlex) represents a framework for widespread access to multiplexed imaging and computational image analysis of clinical specimens at a relatively high throughput and subcellular resolution.

Acute bronchoconstriction is the leading cause of asthmatic sudden death following allergen exposure. The authors show that the systemic increase of LPA following inhaled allergen or bradykinin challenge activates the carotid bodies through TRPV1 and LPA-specific receptors and that systemic TRPV1 and LPA-specific receptor antagonists ameliorate acute bronchoconstriction.

Non-nutritive sensory components of high-fat diet, such as bacon flavour, are sufficient to impair metabolic health in offspring in mice.

The authors previously pinpointed OLAH (oleoyl-ACP-hydrolase) as a driver of life-threatening viral diseases. Here, the authors identify increased IL-18Rα expression on CD8⁺ T cells, which acquire a reduced cytotoxic signature, correlates with severe respiratory viral infection of influenza A virus, RSV and COVID-19.

The functional and causal relationships among the inferotemporal face patches remain elusive. Here, using fMRI and pharmacological inactivation, the authors discover an antero-posterior bidirectional and fundal-lateral parallel organization of these face patches.

Calmodulin-dependent kinase 4 (CaMK4) has been implicated in humoral immunity. Here, the authors demonstrate that CaMK4 expression controls the differentiation of T follicular helper cells, leading to the expansion of pathogenic B cells in systemic lupus erythematosus.

Human challenge studies with SARS-CoV-2 have shown changes in the innate and adaptive immune response. Here the authors are examining potential correlates of infection in virus challenged recipients by assessing baseline immune parameters and how this predicts virus control.

A platform for mRNA lipid nanoparticle delivery to the placenta to treat pre-eclampsia is shown to improve fetal and maternal health in mice and has potential clinical applications in obstetric disorders and women’s health.

Zonal positioning in the liver determines whether the CTNNB1 oncogene can induce liver cancer.

Microglia play key roles during early neurodevelopment. Here the authors show that microglia are important mediators of ocular dominance plasticity (ODP). Microglia respond to monocular deprivation during the visual critical period, and disrupting microglial P2Y12 purinergic receptor abrogates ODP.

Cancer evolutionary dynamics are quantitatively inferred using a method, EVOFLUx, applied to fluctuating DNA methylation.

Understanding the mechanisms underlying the survival of drug tolerant persister cells following chemotherapy remains elusive. Here, multi-omics analysis and experimental approaches show that the germ-cell-specific H3K4 methyltransferase PRDM9 promotes metabolic rewiring in glioblastoma stem cells.

Here, authors identify granulocyte-colony stimulating factor as a potent mediator of cocaine-induced adaptations, and show that it can alter the motivation for cocaine.

FACED 2.0 builds on and expands the capabilities of the free-space angular-chirp-enhanced delay microscopy approach. Its high speed, large field of view and volumetric coverage enable two-photon voltage imaging of hundreds of neurons or calcium imaging of thousands of neurons in the mouse or zebrafish brain.

Targeted nanodrug delivery is crucial to treat respiratory diseases, but profiling the delivery and dynamics of nanoparticles (NPs) within the lung is a challenging task. Here, the authors present LungVis 1.0, an AI-driven 3D imaging ecosystem to profile inhaled substances in distinct lung regions while uncovering the role of tissue-resident macrophages in the fate of NPs.

Epithelial host defense to rhinovirus infections is enhanced by targeting the mitochondrial metabolic regulator, PGC-1a. Using metabolomics and proteomics, Michi et al show that human airway epithelial cells mount a barrier-protective early glycolysis-shift in response to rhinovirus, and that by targeting PGC-1a early in infection, epithelial barrier function, viral defense and pathology are improved.

Here the authors show that a high-fat diet in pregnant mice can release silencing of the imprinted Dlk1 locus in multiple generations of offspring. They found that this occurs via changes in microRNA expression at the locus of interest, as well as transcriptional changes across the genome, in the developing oocytes.

Here, Bottery et al show that resistance to next generation antifungals is more likely to occur within azole resistant Aspergillus fumigatus due to the close linkage between a globally distributed azole resistance allele and a DNA repair variant which elevates mutation rates.

Stimulator of interferon genes (STING) is known to translocate from ER to Golgi while orchestrating type I interferon responses to DNA. Here, the authors show single-molecule resolution images of STING clustering at the trans-Golgi network, where it acts as a scaffold to trigger downstream signaling.

Severe COVID-19 requires immediate and targeted intervention that is efficient against SARS-CoV-2 and its variants. Authors show here the therapeutic potential of engineered natural killer cells that simultaneously express a chimeric antigen receptor targeting the spike protein of SARS-CoV-2, and IL-15, a cytokine that enhances the function and survival of their own.
