Clostridioides difficile peptidoglycan modifications

Current Opinion in Microbiology, 2022
The cortex and peptidoglycan of Clostridioides difficile have been poorly investigated. This last decade, the interest increased because these two structures are highly modified and these modifications may be involved in antimicrobial resistance. For example, C.

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Synergistic Induction of Eotaxin and VCAM-1 Expression in Human Corneal Fibroblasts by Staphylococcal Peptidoglycan and Either IL-4 or IL-13

Allergology International, 2011
Background: Common features of allergic or atopic ocular and skin diseases are the participation of Th2 lymphocytes and eosinophils and colonization by Staphylococcus aureus. To examine the role of interaction between Th2 cells and bacterial infection in

The Wolbachia Genome of Brugia malayi: Endosymbiont Evolution within a Human Pathogenic Nematode [PDF]

, 2005
Complete genome DNA sequence and analysis is presented for Wolbachia, the obligate alpha-proteobacterial endosymbiont required for fertility and survival of the human filarial parasitic nematode Brugia malayi. Although, quantitatively, the genome is even

Bioreactivity of peptidoglycan in seawater [PDF]

Aquatic Microbial Ecology, 2007
The components of bacterial peptidoglycan (PG), D-amino acids and muramic acid, have been identified as constituents of marine dissolved organic matter (DOM), suggesting that PG is a possible component of the recalcitrant DOM. However, little is known about the bioreactivity of PG directly released from bacterial cells.

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

Advanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

Nanosurgery: Observation of Peptidoglycan Strands in Lactobacillus helveticus Cell Walls [PDF]

arXiv, 2004
The internal cell wall structure of the bacterium Lactobacillus helveticus has been observed in situ in aqueous solution using an atomic force microscope (AFM). The AFM tip was used not only for imaging but presumably to remove mechanically large patches of the outer cell wall after appropriate chemical treatment, which typically leaves the bacteria ...

Anchoring of Surface Proteins to the Cell Wall of Staphylococcus aureus: sortase catalyzed in vitro transpeptidation reaction using LPXTG peptide and NH2-Gly3 substrates [PDF]

, 2000
Staphylococcus aureus sortase anchors surface proteins to the cell wall envelope by cleaving polypeptides at the LPXTG motif. Surface proteins are linked to the peptidoglycan by an amide bond between the C-terminal carboxyl and the amino group of the ...

Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...
