Novel Antimicrobial Peptides That Inhibit Gram Positive Bacterial Exotoxin Synthesis

Abstract: Gram-positive bacteria, such as Staphylococcus aureus, cause serious human illnesses through combinations of surface virulence factors and secretion of exotoxins. Our prior studies using the protein synthesis inhibitor clindamycin and signal transduction inhibitors glycerol monolaurate and α-globin and β-globin chains of hemoglobin indicate that their abilities to inhibit exotoxin production by S. aureus are separable from abilities to inhibit growth of the organism. Additionally, our previous studies suggest … Show more

“…Moreover, defensins can also affect the microbial intracellular processes, such as inhibiting protein synthesis [65] and the activities of ␣-amylases [60] and proteases [106]. Alternatively, these peptides can also induce the inactivation of microbial toxins by protein unfolding [48].…”

“…aureus é um coco Gram-positivo que faz parte da microbiota de seres humanos e atua como um importante patógeno humano, pois é responsável por uma grande variedade de infecções (MERRIMAN et al, 2014). Aproximadamente 40% dos seres humanos apresentam pele e mucosas colonizadas por S. aureus (MERRIMAN et al, 2014), sendo que 20% dos indivíduos devem apresentar colonização nasal persistente, enquanto 30% devem apresentar colonização nasal intermitente (POPOV et al, 2014).…”
