Pro-inflammatory cytokine inhibition in the primate using microencapsulated antisense oligomers to NF-kappaB.

Primary Objective: Antisense oligomers to NF-kappaB (ASO) were incorporated into albumin microspheres to determine if microcapsules containing ASO inhibit pro-inflammatory cytokines to a greater extent than comparable doses of ASO in solution. Phagocytosis of microcapsules and intracellular release of ASO in macrophages was evaluated.

Research Design: Comparable doses of microencapsulated ASO and ASO in solution were evaluated in non-human primates.

Infection-induced modulation of m1 and m2 phenotypes in circulating monocytes: role in immune monitoring and early prognosis of sepsis.

To monitor and better understand the immunoinflammatory sequelae in sepsis and septic shock, systemic and monocyte-related cytokine responses were evaluated in baboons with experimental peritonitis induced by an E. coli-laden fibrin clot. Despite similar bacterial inocula, considerable interindividual variability in clinical manifestation and outcome of infection was observed.
