"As measured by LIVE and DEAD immunofluorescent staining, we found that administration of RBC nanosponges allowed a significant increase in survival of keratinocytes upon coincubation of the cells with the WT SLO producing GAS strain at MOI = 25 (50% survival vs. 20% untreated, Figure XREF_FIG)."

reach
"We then tested the ability of RBC derived nanosponges to block hemolysis induced by coincubation of freshly isolated human RBC with a high level SLO producing WT GAS strain compared to its isogenic DeltaSLO mutant as a control."

reach
"SLO promotes GAS resistance to phagocyte killing and impairs critical phagocyte functions such as oxidative burst, migration, degranulation and neutrophil extracellular trap (NET) production."

reach
"We injected the invasive WT SLO producing GAS strain subcutaneously into the flanks of WT C57bl6 mice and then subsequently treated the mice proximally with either vehicle only control or vehicle + 50 mg/kg of RBC nanosponges at 15 min post-infection, a dose known to be well tolerated by mice in studies of purified alpha-toxin neutralization."
