Radioprotector WR-2721 and mitigating peptidoglycan synergistically promote mouse survival through the amelioration of intestinal and bone marrow damage.
In addition, bacterial cell walls are made of peptidoglycan which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids [51].
In enterococci, under normal conditions, peptidoglycan synthesis is carried out by a ligase enzyme that joins two molecules of D-alanine to form D-Ala-D-Ala.
Peptidoglycans are similar pro-inflammatory substances derived from the outer cell wall of gram positive bacteria.
Kleinstreuer and Xu [42] hence gave [D.sub.0] for metallic nanoparticles penetration through the thin peptidoglycan layer as
The induction of AmpC production is intimately linked to peptidoglycan recycling [6].
Peptidoglycan is the major component of the CW and a crucial structure in stress survival and recalcitrance against antibiotics and host defences.
aureus, a Gram-positive bacterium, consists of a thick peptidoglycan layer and a cytoplasmic membrane.
NOD1, a member of NLRs family, initiates inflammation by recognizing ligands of bacterial peptidoglycan containing [gamma]-D-glutamyl-meso-diaminopimelic acid (iE-DAP), which leads to the activation of NF-[kappa]B and subsequently the release of proinflammatory mediators and chemokines via a series of cascade responses [8-10].

The Mycoplasma species is extremely small and lacks a peptidoglycan cell wall; therefore, it does not appear on gram stain, making it particularly difficult to identify using traditional techniques.
Lysozyme hydrolyzes 1,4-[beta]-linkages between Nacetylmuramic acid and N-acetylglucosamine present in the peptidoglycan. Gram-positive bacteria are highly susceptible to lysozyme because of the presence of peptidoglycan in their cell walls, but lysozyme is not effective in killing Gram-negative bacteria [19-21], which indicates the need for a combination with other compounds.
