Aims: Sepsis is a disease that involves abnormal alterations in the microcirculation, with endothelial dysfunction playing a central role in the pathogenesis and mortality. The exact pathophysiology of brain dysfunction associated with sepsis remains poorly understood and experimental data are scarce. It is likely that cerebral microcirculatory alterations may play a potential role. Thus, the present study sought to investigate whether key angiogenic pathways are altered in the frontal cortexin a clinically-relevant animal model of endotoxemia/sepsis, and verify whether the alterations in angiogenic pathways affect the cerebral capillary density.
Main methods: Male mice at 8 weeks of age were administered either with saline alone (control group) or 20 mg/kg lipopolysaccharide (LPS) (treatment group) at different time points (1, 3, 6, and 10 h).. View More»
