Drosophila immunity: analysis of PGRP-SB1 expression, enzymatic activity and function.

PLoS ONE, 2011
Peptidoglycan is an essential and specific component of the bacterial cell wall and therefore is an ideal recognition signature for the immune system. Peptidoglycan recognition proteins (PGRPs) are conserved from insects to mammals and able to bind PGN ...

D-alanylation of Teichoic Acids in Bacilli impedes the immune sensing of peptidoglycan in Drosophila

, 2023
Modification of cell wall components is a prominent mean for pathogens to hinder host immune defenses. Here, using the Drosophila model, we aimed at characterizing the role of D-alanine esterification of teichoic acids (TAs) in the resistance of Bacillus

Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems

Advanced NanoBiomed Research, EarlyView.
Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.

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 enzymology of Streptococcus pneumoniae peptidoglycan polymerisation [PDF]

Bacterial cell survival depends on intact peptidoglycan, an extensive cell wall polymer of alternating N-acetylglucosamine and N-acetylmuramic acid residues, cross-linked by short peptides.

Functional characterization of a short peptidoglycan recognition protein, PGRP5 in grass carp Ctenopharyngodon idella

, 2013
Peptidoglycan recognition proteins (PGRPs), which are evolutionarily conserved from insects to mammals, recognize bacterial peptidoglycan (PGN) and function in antibacterial innate immunity.

Bacterial peptidoglycan recycling

Trends in Microbiology
During growth and division, the bacterial cell wall is remodeled, resulting in the liberation of peptidoglycan (PG) fragments which are typically reinternalized and recycled. Recycling of PG has been studied in a few model species, but its importance and diversity are not yet well understood.

Characterisation of pneumococcal peptidoglycan cross-linking enzymology [PDF]

Despite the introduction of penicillin, infections caused by Streptococcus pneumoniae are associated with significant morbidity and mortality. As a result, there is an urgent need for successful identification of new drug targets within the organism ...

Anammox Planctomycetes have a peptidoglycan cell wall [PDF]

, 2015
Planctomycetes are intriguing microorganisms that apparently lack peptidoglycan, a structure that controls the shape and integrity of almost all bacterial cells.
