Increased intestinal permeability exacerbates sepsis through reduced hepatic SCD-1 activity and dysregulated iron recycling

Here Kumar et al. show that increased intestinal permeability reduces hepatic de novo lipogenesis, affecting plasma membrane fluidity and lifespan of RBCs, and the resulting increase in iron levels promotes bacterial growth. This mechanism may explain the increased risk of sepsis associated with inf...
