abstract：:We aimed to investigate if angiopoietin-2 (Ang-2) participates in the septic process and what may be the role of monocytes as a site of release of Ang-2 in sepsis. Concentrations of Ang-2 were estimated in sera and in supernatants of monocytes derived form one already described cohort of 90 patients with septic syndro...
