Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Infectious MedicineMultiple sclerosis (MS) is a chronic neurodegenerative and autoimmune disease of the central nervous system (CNS). While the exact etiology remains unclear, emerging evidence suggests that bacterial toxins play significant roles in MS pathogenesis and ...

Toxins in Fermented Foods: Prevalence and Preventions—A Mini Review
Toxins, 2018 Fermented foods (FF) are widely consumed around the world, and FF are one of the prime sources of toxins and pathogenic microbes that are associated with several foodborne outbreaks.

The Variety in the Common Theme of Translation Inhibition by Type II Toxin–Antitoxin Systems
Frontiers in Genetics, 2020 Type II Toxin–antitoxin (TA) modules are bacterial operons that encode a toxic protein and its antidote, which form a self-regulating genetic system. Antitoxins put a halter on toxins in many ways that distinguish different types of TA modules.

Bacterial intracellularly active toxins: Membrane localisation of the active domain
, 2020 International audienceNumerous bacterial toxins exert their activity by inactivating or modulating a specific intracellular host target. For this purpose, these toxins have developed efficient strategies to overcome the different host cell defences ...

, 2021 A majority of toxins produced by type I toxin–antitoxin (TA-1) systems are small membrane-localized proteins that were initially proposed to kill cells by forming non-specific pores in the cytoplasmic membrane.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Membrane‐Damaging Toxins: Family of RTX Toxins
, 2003 The major cellular effect of RTX toxins has been ascribed to their pore‐forming capacity, resulting in plasma membrane lesions and osmotic lysis.

Molecular Biology of Escherichia coli Shiga Toxins’ Effects on Mammalian Cells
, 2020 Shiga toxins (Stxs), syn. Vero(cyto)toxins, are potent bacterial exotoxins and the principal virulence factor of enterohemorrhagic Escherichia coli (EHEC), a subset of Shiga toxin-producing E. coli (STEC).

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
