Advances in engineering and applications of synthetic phase-separated membraneless organelles in biotechnology
, Synthetic and Systems Biotechnology, Vol: 13, Pages: 37-49, ISSN: 2405-805XMembraneless organelles (MLOs) formed through liquid-liquid phase separation (LLPS) constitute crucial dynamic microenvironments within cells, capable of selectively concentrating specific molecules and regulating biochemical reactions. Based on the working mechanisms of natural MLOs, researchers have designed and constructed various synthetic MLOs. These MLOs have been applied in regulating enzyme activity, optimizing metabolic pathways, regulating gene expression, producing recombinant proteins, and developing functional biomaterials. Here, we systematically summarized the design strategies, characterization techniques, and client protein recruitment methods for synthetic MLOs, and categorically reviewed their application progress in the biotechnology field. We also discussed current challenges faced in the practical applications of synthetic MLOs and future research directions. This review aims to provide theoretical guidance and practical reference for the design and application of LLPS-driven synthetic MLOs, thereby promoting their innovative development in synthetic biology and biotechnology.

Easy repair enabled by an interleaving ‘weak link’ strategy to localise damage in laminated fibre-reinforced polymer-matrix composites
, Composites Part B: Engineering, Vol: 323, ISSN: 1359-8368An interleaving strategy for polymer matrix composite laminates is proposed to create a mechanical fuse allowing interlaminar damage to be localised in the interleaf, which can subsequently be repaired. To create the mechanical fuse, the laminates are interleaved with thermoplastic polymer films with suitable mechanical properties to act as a repairable weak link. Carbon fibre/epoxy laminates interleaved with polystyrene (PS) were investigated by three-point flexure and static indentation tests. In the three-point bending tests, shear–driven damage was observed in the interleaved region, and this damage was subsequently repaired by application of heat and pressure. After two damage-repair cycles, the stiffness was virtually fully recovered, and the shear strength restored to 88% of the pristine value. In the static indentation tests, the stiffness and damage onset force of the specimens recovered to 84% and 70% of the pristine values, respectively, after three damage-repair cycles.

A potato late blight pathogen effector interacts with ENTH-domain protein TOL9a and an activated helper NLR to suppress immunity.
, Sci Adv, Vol: 12Pathogens counteract central nodes of NLR immune receptor networks to suppress immunity. However, the mechanisms by which pathogens hijack helper NLR pathways are poorly understood. We show that an effector from the late blight pathogen Phytophthora infestans interacts with the host protein NbTOL9a and a helper NLR to suppress immunity. We solved the crystal structure of the RXLR-LWY effector AVRcap1b in complex with the ENTH domain of NbTOL9a. The structure revealed that, unlike other RXLR-LWY effectors, AVRcap1b has a previously unidentified L-shaped fold that defines a distinct structural family of effectors in the genus Phytophthora. We defined the AVRcap1b/NbTOL9a binding interface and designed effector mutants that do not bind NbTOL9a, impairing immune suppression. This suggests that ENTH binding is required for full virulence activity. Last, we show that AVRcap1b associates specifically with activated NbNRC2 independently of NbTOL9a binding. We propose a model in which the effector interconnects NbNRC2 with the NbTOL9a pathway. Our results illustrate a previously uncharacterized pathogen mechanism to hijack NLR pathways and suppress immunity.

Toll-like receptor 5 protects against murine lung fibrosis through reduced dysbiosis, and TLR5 deficiency is associated with human IPF.
, Sci Transl Med, Vol: 18Idiopathic pulmonary fibrosis (IPF) is a devastating pulmonary disease with no curative treatment other than lung transplantation that results from maladaptive responses to lung epithelial injury; however, the underlying mechanisms remain unclear, and treatment options are limited. Here, we showed that deficiency in the innate immune receptor toll-like receptor 5 (TLR5) is associated with IPF in humans and with increased susceptibility to bleomycin-induced pulmonary fibrosis in mice and that activation of lung epithelial TLR5 through a synthetic flagellin analog protected mice from experimental fibrosis. Mechanistically, epithelial TLR5 activation induced antimicrobial gene expression and ameliorated lung dysbiosis after injury. In contrast, TLR5 deficiency in mice and patients with IPF was associated with lung dysbiosis. Elimination of the microbiome in mice through administration of antibiotics abolished the protective effect of TLR5, and reconstitution of the microbiome by fecal microbiota transplantation rescued the observed phenotype. In conclusion, these studies revealed that TLR5 protects against pulmonary fibrosis through effects on the lung microbiota, providing insight into therapeutic approaches that may ultimately benefit patients with IPF.

A hydrophobic core in the coiled-coil domain is essential for NRC resistosome function.
, New Phytol, Vol: 250, Pages: 3247-3263The nucleotide-binding leucine-rich repeat protein (NLR) required for cell death (NRC) family represents a group of helper NLRs that are required by sensor NLRs to execute hypersensitive cell death during pathogen infection. NRCs contain an N-terminal coiled-coil (CC) domain essential for their function, yet our knowledge of how this domain contributes to NRC function remains limited. Using site-directed mutagenesis and transient expression in Nicotiana benthamiana, we screened conserved hydrophobic residues among NRCs and identified seven required for NRC4-mediated cell death, revealing a hydrophobic feature within the CC domain that contributes to NRC-mediated immunity. Structural analysis revealed that four of these residues form a hydrophobic core in the CC domain. This hydrophobic core is important for NRC4 subcellular localization, oligomerization, and phospholipid association, but not for NRC4 focal accumulation at the extrahaustorial membrane during Phytophthora infestans infection. Sequence analysis and functional assays revealed that this core is highly conserved in NRCs and some singleton NLRs but has degenerated in NRC-dependent sensor NLRs. Our study identifies a hydrophobic feature in the CC domain of NRCs and reveals its contribution to NLR-mediated immunity.

Targeting Inflammation in Bronchiectasis.
, Drugs, Vol: 86, Pages: 797-812Bronchiectasis is defined by chronic infection, dysregulated inflammation and impaired mucociliary clearance underpinning progressive structural lung injury. While airway infection remains a clinical hallmark, numerous studies demonstrate that excessive neutrophil-dominated inflammation is a key determinant of disease severity, exacerbation risk and quality of life. Recent developments have transformed our understanding of inflammatory drivers uncovering distinct inflammatory endotypes defined by dominant microbial species, pattern-recognition receptor activation, inflammasome signalling, Th17-associated cytokine networks and failures of mucosal immunity. The emerging roles of viral-bacterial interactions, fungi, pathobionts and the broader microbiome challenge the conventional infection-only paradigm and highlight gaps in current therapeutic strategies. Such developments underpin the rationale behind anti-inflammatory strategies in bronchiectasis, ranging from suppression of neutrophil-driven injury through direct neutrophil elastase or upstream dipeptidyl peptidase-1 (DPP-1) inhibition, to immunomodulatory macrolides, toward therapies aimed at recalibrating epithelial and mucosal homeostasis. While several antibacterial and anti-infective trials have produced mixed results, this is likely to reflect unresolved heterogeneity in microbiome composition and host immune signalling. In contrast, emerging anti-inflammatory strategies show strong positive signals, reinforcing the need for better endotyping and biomarker-guided patient selection. Here we synthesize recent mechanistic and clinical insights to propose a more integrated framework for understanding and ultimately targeting airway inflammation in bronchiectasis.

Scalable structural supercapacitors with graphene-modified high-surface-area electrodes
, Composites Science and Technology, Vol: 279, ISSN: 0266-3538Electrification, including emerging technologies such as structural supercapacitors, is critical in realizing carbon-neutral transportation. A fundamental challenge is the trade-off between mechanical properties and energy storage capabilities. We report the fabrication of structural supercapacitors with a novel fibre-fibre interface to improve the interlaminar strength and encapsulation while considering the effect of structural resin on energy storage performance. The synthesized graphene nanoplatelets-modified electrodes attain a high specific surface area of ∼231 m<sup>2</sup> g<sup>−1</sup> - outperforming comparable carbon-based electrodes. We learned that the use of a gel-polymer electrolyte (GPE) separator containing 60 wt% Li-salt eliminates the requirement of electrolyte infusion and showed the highest values for conductivity for the cell produced using GPE. The implementation of glass fabrics (GFs) into the GPE improved the flexural modulus by ∼22%, while retaining the mechanical strength of the cells. The multifunctional performance of the produced SSCs were on par or even outperformed the performances of SSCs reported in literature. A proof-of-concept prototype demonstrates that gel-polymer electrolyte cells can retain charges for longer than those with a glass fibre separator. Cumulatively, these offer the possibility of conventional composite manufacturing techniques to scale-up and eliminate delamination issues arising from different thermal expansion coefficients which also addresses the balance between mechanical stability and electrochemical performance. Our findings support the advancement of durable, lightweight energy storage and delivery systems for sustainable transportation, with potential applications in robotics and wearable technologies.
