Kao et al. provide insight into the metabolic requirements of IL-17A-producing γδ T cells, offering an actionable target to treat psoriasis by inhibiting fatty acid synthesis.

Zaza and colleagues demonstrate that DNA-PAINT on a spinning disk confocal microscope with optical photon reassignment enables high-resolution imaging across large fields and imaging depths, resolving nanoscale protein organisation in both cells and tissues.

Lee et al. use an aggregation-prone CLN4 mutant that causes lysosomal damage in neurons and show that in non-neurons, the ubiquitin ligase CHIP prevents CLN4-dependent lysotoxicity via microautophagy.

Recent data have shown that orexins regulate not only wakefulness but also feeding, emotional behaviour, reward seeking and autonomic and endocrine responses. Takeshi Sakurai summarizes these findings and proposes that the orexin system regulates the response of the body to its internal and external environments to support various motivated behaviours.

Filter-aided expansion proteomics facilitates spatial proteomics at subcellular resolution by integrating tissue expansion, imaging-guided microdissection and filter-aided in-gel digestion. This combination enhances the resolution, throughput and reproducibility for data-independent acquisition-based mass spectrometry analysis.

Membrane trafficking is essential for organelle biogenesis. Here, the authors discover an alternative assembly of the Commander trafficking complex and show its role in melanosome biogenesis and in a subtype of albinism.

In vitro reconstitution and in vivo live-cell imaging of LHX2–EBF1–LDB1 enhancer hubs in olfactory sensory neurons reveals that these transcription factors form condensates with solid, rather than liquid, phase properties.

Combining behavioral data, electrophysiology and modeling, the authors show that the human brain synchronizes visual signals by adjusting axonal conduction speed in the retina, revealing a previously unknown mechanism for precise perceptual timing.

Chen et al. show that PEX39 cooperates with PEX7 in the peroxisomal import of proteins containing a PTS2 site and uncover an (R/K)PWE motif in PEX39 and PEX13 that binds to PEX7 and facilitates the import of PTS2-containing proteins.

Targeting histone deacetylases (HDACs) alone has shown limited success in solid tumours. Here, authors report that the HDAC1/2 inhibitor romidepsin confers responsiveness to receptor tyrosine kinase inhibitors, with enhanced therapeutic effects in models of hepatocellular carcinoma, leading to tumour regression and an immune-stimulatory profile.

Two algal proteins, MITH1 and SAGA1, play key roles in formation of membranes that deliver CO₂ to the pyrenoid, a CO₂-concentrating organelle. Their discovery marks a key milestone towards engineering a pyrenoid into land plants for improved yields.

mBaoJin is a monomeric derivative of the bright and photostable green fluorescent protein StayGold. mBaoJin offers favorable photophysical properties for use in diverse protein tagging and subcellular labeling applications.

During HCMV infection, mitochondrial progenies derived from peripheral fragmentation can be protected from mitophagy and result in elevated respiration through a mechanism leveraging ER-mitochondria and inter-mitochondria membrane contacts.

The red fluorescent protein mScarlet3-H is bright, photostable and very robust to high temperature, chaotropic conditions and oxidative environments. mScarlet3-H works well in correlative light and electron microscopy, tissue clearing and time-lapse super-resolution microscopy.

Interactions with the extracellular matrix (ECM) control tumor proliferation, invasion and metastasis. Here, authors provide spatial information on ECM organization and how it influences tumor cell invasive and metastasis properties through induction of cytoskeletal and transcriptional memory.

DNA double-strand breaks induce local genome maintenance and inhibition of replication initiation at nearby topologically associating domains without affecting global DNA synthesis.

Using metabolic dysfunction-associated steatohepatitis-driven hepatocellular carcinoma mouse models, an ATP citrate lyase inhibitor reduces tumour burden and enhances efficacy of current standards of care.

The genetically encoded sensor hCRAFi-CCR2 enables detection of chemokines binding to the CCR2 receptor, such as the main ligand CCL2 but also CCL7, CCL8, CCL13 and CXCL1. The sensor’s capabilities are demonstrated in cell culture and in various mouse models in vivo.

The involvement of nuclear pore proteins in cellular mechanosensing and metastasis is unclear. Here the authors identify that nuclear pore protein NUP210 promotes metastasis through the interaction with mechanotransducer LINC complex protein and chromatin to regulate mechanosensitive genes.

Deltex E3s modify ADP-ribosylated targets with ubiquitin, creating a hybrid modification whose readers remains unknown. Here, the authors synthesise a non-hydrolysable probe that mimics the modification and identify RNF114 as an interactor. RNF114 binds tightly to this modification and further elongates it with a K11-linked ubiquitin chain.

Centromere fragility can drive tumourigenesis, so protective mechanisms are important. Here, the authors suggest that the PBAF chromatin remodelling complex, which is frequently misregulated in cancer, helps to maintain the integrity of centromeres.

LINE-1 retrotransposons are a type of mobile DNA element normally repressed in the body. Here the authors show that LINE-1 sequences can jump in mouse parvalbumin interneurons and also promote the transcription of key parvalbumin interneuron genes.

Hydrogel-based tissue expansion proteomics represents an emerging spatial proteomics approach. Here, the authors develop the filter-aided expansion proteomics (FAXP) strategy, enabling proteomic analysis of single cells and nuclei in formalin-fixed paraffin-embedded (FFPE) tissue sections.

The density and size of contact gradients between the endoplasmic reticulum and the plasma membrane control the speed and direction of cell migration by restricting receptor signalling to the front.

How signaling pathways recruit SWI/SNF chromatin remodeling complexes is not known. Here the authors suggest a ubiquitin directed mechanism targeting SWI/SNF for Wnt pathway dependent transcription, important for development and cancer.

Park et al. show that in the process of metastasis, dying tumor cells enhance the outgrowth of their surviving counterparts via nuclear expulsion, resulting in an extracellular DNA–protein complex that activates RAGE receptors on tumor cells.

The orientation of elongated cells often rotates once around the center in tissue. Such structures are called +1 topological defects and play some roles in biological development. By inducing various types of +1 defects in cell layers, the authors found previously overlooked active forces, as the cells gathered at the core of all types of +1 defects.

The authors report observations of a dense and inhomogeneous ring at a surprisingly large distance from the trans-Neptunian body Quaoar.

The bile ducts of the liver form a network of large ducts and small ductules, though how they are patterned remains unclear. Hrncir et al. show that Sox9 is required for the morphogenesis of small intrahepatic bile ductules in mice, highlighting distinct genetic requirements that drive bile duct heterogeneity.

Dissecting the adaptive exercise response of the neurogenic stem-cell niche in the dentate gyrus by single-nucleus RNA sequencing reveals the molecular mediators that underlie exercise’s protective effects in Alzheimer’s disease.
