This video demonstrates the activation of a mouse's peritoneal macrophages using intravenous immunoglobulin and bacterial lipopolysaccharide. The co-stimulation activates the peritoneal macrophages into anti-inflammatory macrophages possessing immune regulatory activity.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Challenging Mice in Vivo with intravenous immunoglobulin and lipopolysaccharide (IVIg+LPS) and Harvesting Peritoneal Macrophages Weigh each mouse. Calculate the volume of IVIg (100 mg/mL stock concentration) needed to provide a final dose of 2.5 g/kg body weight. Calculate the amount of LPS (100 μ…
