An antiphage defence system has an activation mechanism that relies on the sensing of phage-encoded proteins that enforce geometry crucial to activation and are not typically present in non-infected cells.

The role of normally silenced transposable elements (TEs) in tumorigenesis remains unclear. Here, the authors show that increased expression of TEs in both patients and mice with colitis or by DNA hypomethylating drugs elicits a viral mimicry response that suppresses tumorigenesis. This viral mimicry response inhibits the stemness of cancer initiating cells in a cell autonomous manner.

Here the authors show that endogenous or therapeutically delivered GDF-15 activates brainstem neurons that trigger splenic β-adrenergic signaling. This, in turn, suppresses autoreactive T cells and reduces neuroinflammation, identifying a possible target for multiple sclerosis treatment.

Metastatic triple negative breast cancer (mTNBC) has limited treatments options. Here, this group presents a combination of low-dose cyclophosphamide, anti-CSF1R, and anti-PD-1 therapies to boost immune cell infiltration and reduce recurrence in aggressive TNBC models.

Caspase 8 protein expression is largely absent in small cell lung cancer (SCLC) patients. Here, the authors generate a caspase 8 deletion SCLC mouse model and show that it promotes a neuronal progenitor-like cell state and pre-tumoral immunosuppression triggered by necroptosis that promotes metastasis.

The systemic discovery of metal–small-molecule complexes from biological samples is a difficult challenge. Now, a method based on liquid chromatography and native electrospray ionization mass spectrometry has been developed. The approach uses post-column pH adjustment and metal infusion combined with ion identity molecular networking, and a rule-based informatics workflow, to interrogate small-molecule–metal binding.

Mitochondrial DNA heteroplasmy associates with context-specific nuclear CpG methylation, supported by a cell model. Heteroplasmy–CpG scores relate to mortality and cardiovascular risk, though direction and mechanisms remain unclear.

The composition and potential roles of extracellular vesicles released by gut archaea are poorly understood. Here, Weinberger et al. show that extracellular vesicles produced by human gut-derived methanogenic archaea are enriched in adhesin-like proteins, can be taken up by macrophages, and elicit responses in immune and epithelial cells.

The CARD11-BCL10-MALT1 (CBM) complex governs canonical NF-κB signaling and MALT1 protease activation downstream of TCR stimulation. Here, the authors evaluate the contribution of the E3 ligases LUBAC and TRAF6 in controlling CBM activity, using Jurkat and primary human T cells. Unlike TRAF6, LUBAC is largely dispensable for activating NF-κB, but it modifies BCL10 and regulates MALT1 protease activity by controlling substrate selectivity.

PepMLM designs peptide binders against diverse targets using masked language modeling.

In flowering plants, DNA–FD–14-3-3 recruits FT to the florigen activation complex both through DNA–FT interactions and by reducing liquid phase condensation of FD protein, which promotes dimerization, leading to FT recruitment.

Aarrestad et al. show that, in contrast to psychedelics, the nonhallucinogenic psychoplastogen tabernanthalog promotes neuroplasticity through 5-HT_2AR activation without immediately increasing extracellular glutamate levels or immediate early gene expression.

The early genetic evolution of uveal melanoma (UM) remains poorly understood. Here, the authors perform genetic profiling of 1140 primary UMs, including 131 small early-stage tumours, finding that most genetic driver aberrations have occurred by the time small tumours are biopsied; in addition, the15-gene expression profile discriminant score can predict the transition from low- to high-risk tumours.

Mutations in elongation factor G protect bacteria from aminoglycoside antibiotics through unknown mechanisms. Here, the authors show that the mutations selectively slow the movement of antibiotic-bound ribosomes along mRNA, which prevents error-prone protein synthesis and thus membrane damage and antibiotic uptake.
