The tumour microenvironment features influencing response to neoadjuvant immunochemotherapy (nICT) in esophageal squamous cell carcinoma (ESCC) remain to be explored. Here, single cell and TCR sequencing on pre- and post- nICT treatment ESCC tissues identifies the presence of CXCL13⁺CD8⁺ T cells as a predictor of improved response and the enrichment of TNFRSF4⁺CD4⁺ Tregs as a marker of treatment resistance.

Drivers of viral evolution in SARS-CoV-2 are insufficiently understood. In this study, the authors show how a key SARS-CoV-2 mutation, NSP4 T492I, is potentially responsible for accelerating genome evolution to develop adaptive variants (e.g. Omicron).

Epstein-Barr virus is associated with increased cancer risk. Here, the authors analysed two population-based prospective cohorts in Southern China to examine the association between increased seropositivity and the risk of multiple cancer types.

Systemic administration of TRL7/8 agonists enhances anti-tumor immunity by enhancing dendritic cell (DC) activation, but also causes systemic toxicity. Here, the authors show that, in tumor mouse models, a radiotherapy-activated, N-oxide imidazoquinoline prodrug promotes controlled, local activation of intratumoral DC-T cell dynamics, while promoting systemic anti-tumor responses.

Here the authors show that viral infections facilitate accumulation of cellular iron by degradation of iron exporter ferroportin (FPN1), and that high intracellular iron suppresses type I IFN responses and autophagy by promoting TBK1 hydroxylation and STING carbonylation.

Piezoelectric materials for bone repair usually require scaffold filling and external stimulation. Here, the authors present a self-reinforced chip that can spontaneously generate piezoelectric effect under physiological vibrations to achieve scaffold-free repair of critical-sized bone defects

This study reveals that CYBDOM proteins promote drought tolerance by regenerating apoplastic ascorbic acid (AsA) and activating autophagy through interaction with RbohD, and link AsA redox, ROS and selective autophagy in plant stress responses

The production of ammonia via the Haber–Bosch process is carbon-intensive and centralized, but electrochemical methods such as lithium-mediated processes in organic electrolytes could enable decentralized production using renewable energy. Calcium is now shown to mediate nitrogen reduction for ammonia synthesis.

There is still no consensus on tumour type-specific cancer stem cell markers. Here, the authors demonstrate that ITGA7 is a potential functional marker of oesophageal cancer stem cells involved in the resistance to chemotherapy and metastasis through activation of FAK-mediated signalling.

The advancement of sodium halide solid-state electrolytes can propel high-energy-density all-solid-state sodium-ion batteries. Here, the authors present a LaCl₃-based electrolyte facilitating rapid Na⁺ ion conduction along the c-axis diffusion channel, ensuring high capacity even at elevated current densities.

With nature in cities, as with the chemicals we ingest, the dose can make the difference. This analysis looks across other studies to find that, in practice, a moderate ‘dose’ of urban greenness provides the greatest mental health benefits.

Worldwide, the number of only-child families is increasing. This research examines how growing up without siblings affects adult brain structure, function and connectivity, cognition, personality and mental health.

Catalytic enantioselective three-component aminative difunctionalization of 1,3-dienes offers a straightforward methodology to access chiral allylic amines, but using anilines as aminating reagents is underdeveloped. Here, the authors report a copper-catalyzed enantioselective radical three-component 1,4-perfluoroalkylamination of 1,3-dienes with anilines and perfluoroalkyl reagents.

Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) is a life-threatening condition different from self-limiting nature of Epstein-Barr virus-induced infectious mononucleosis (IM).
