Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

Biotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.

Effects of outer membrane vesicle formation, surface-layer production and nanopod development on the metabolism of phenanthrene by Delftia acidovorans Cs1-4. [PDF]

PLoS ONE, 2014
Nanopods are extracellular structures arising from the convergence of two widely distributed bacterial characteristics: production of outer membrane vesicles (OMV) and formation of surface layers (S-layers). Nanopod production is driven by OMV formation,

Membrane Distribution of the Pseudomonas Quinolone Signal Modulates Outer Membrane Vesicle Production in Pseudomonas aeruginosa

mBio, 2017
The Pseudomonas quinolone signal (PQS) is an important quorum-sensing molecule in Pseudomonas aeruginosa that also mediates its own packaging and transport by stimulating outer membrane vesicle (OMV) formation.

Bacterial Outer Membrane Vesicle-Mediated Cytosolic Delivery of Flagellin Triggers Host NLRC4 Canonical Inflammasome Signaling

Frontiers in Immunology, 2020
Bacteria-released components can modulate host innate immune response in the absence of direct host cell–bacteria interaction. In particular, bacteria-derived outer membrane vesicles (OMVs) were recently shown to activate host caspase-11-mediated non ...

Targeting the intratumoral microbiota to overcome cancer immunotherapy resistance

Interdisciplinary Medicine, EarlyView.
This review delineates the mechanisms of intratumoral microbiota in cancer immunotherapy resistance, and offers strategies for microbiota‐targeted precision immunotherapy. Abstract Cancer remains a significant global health threat. The tumor microenvironment (TME) is a sophisticated ecological niche that exerts a pivotal effect on treatment outcomes ...

Mitochondria‐targeted nanomedicine for cancer therapy: Targeting strategies, therapeutic mechanisms, and translational challenges

Interdisciplinary Medicine, EarlyView.
This review highlights recent advances in mitochondria‐targeted nanomedicine for cancer therapy. It summarizes key targeting strategies and delineates four principal therapeutic mechanisms: oxidative stress–induced mitochondrial dysfunction, disruption of energy metabolism, direct mitochondrial damage, and induction of immunogenic cell death.

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.
