Based on our current knowledge of microbial-immune interaction in PWH- and SIV-infected NHPs, significant alteration to the gut microbiome is anticipated to affect progressive HIV or SIV infections. Indeed, treatment of NHPs with vancomycin, an antibiotic against gram-positive bacteria, led to sign...
The Gram-positive bacterium Streptococcus pyogenes, on the other hand, was two times as sensitive to the CRS4C-1a/1a homodimer as that to the CRS4C-2/3a heterodimer. This capacity of CRS- peptides to form covalent dimers increases, thus, their antimi- crobial repertoire, as does the ...
the monomeric peptidoglycan unit undergoes translocation across the cytoplasmic membrane for incorporation into the cell wall (reaction III). It is noteworthy that this interpeptide bridge formation is limited to some Gram-positive bacteria, as highlighted by research.38Note: To better demonstrate the ...
On the other hand, defA and defB were upregulated in the midgut in response to oral infection with gram-positive bacteria (Vieira et al., 2016). 3.3.4. Phenoloxidases (PO) PO is an enzyme involved in the oxidation of phenols and quinones. This oxidation consists of a cascade of ...
Furthermore, the infection of pea aphids with Gram-positive bacterium S. aureus and fungus B. bassiana induced the production of winged offspring in the aphids that were fed alfalfa (Figure 2). Previous research revealed that pea aphids could invest in terminal reproduction in response to ...
Recent data has indicated that salivary HSP70/HSPAs bind both gram-positive (Streptococcus mutans and mitis) and gram-negative (Escherichia coli) bacteria [46–48]. Since HSP70/HSPAs are known to be able to form dimers and oligomers, the agglutinating function of salivary HSP70/HSPAs could be...
Listeria monocytogenes is a Gram-positive bacterium that causes severe infections in immunocompromised individuals (Gellin and Broome, 1989). In a mouse model, intravenously inoculated bacteria are rapidly cleared from the bloodstream and predominantly infect the spleen and liver. At the cellular level,...
For example, Gram-positive bacterium Deinococcus radiodurans possesses the ability to reduce ROS induced injury to Fe-S proteins by eliminating the cellular iron outside the cytosol [140]. Studying the underlying mechanisms for sequestration of susceptible or damaging molecules can provide...
