Macrophages are immune cells that phagocytize pathogens and act as antigen presenting cells. Macrophages are critical in regulating the adaptive immune response and play a key role in neutralizing infection. Macrophages exhibit a variety of phenotypes which have different energy requirements. In the case of HSV-1 infection the virus has been shown to alter metabolic processes of its host. Utilizing a XF24 Extracellular Flux Analyzer the metabolic activity of M0, M1, and M2 (IL-4, IL-13, and IL-10) RAW 264.7 macrophages was quantified for both uninfected cells and in response to HSV-1 infection. The analysis showed uninfected M0 and M2 (IL-4, IL-13, IL-10) macrophages undergo glycolysis and mitochondrial respiration for energy metabolism while M1 macrophages only undergo glycolysis. HSV-1 showed the ability to alter metabolism in macrophages by inhibiting oxidative phosphorylation. This inhibition leads to increased rates of glycolysis with variability shown among the macrophage phenotypes. As HSV-1 is dependent upon its host cell for energy production the degree of response can be correlated to viral replication.
