The effect of antioxidant supplementation on the viral load of HIV

A byproduct of cellular respiration, small highly reactive molecules called reactive oxygen species (ROS) play a crucial role in cell signalling and infection control. However, high levels of ROS can cause significant damage to cell structure and function. Under normal conditions, a healthy diet supplying adequate quantities of antioxidants helps to maintain a safe level of ROS. Studies have shown that infection with the human immunodeficiency virus (HIV) results in an increase in oxidative stress. Acting like a catalyst in nuclear factor kB activation, ROS in turn lead to faster progression of HIV infection, and cause CD4+ T-cell apoptosis. Clinical studies have explored the possibility of raising antioxidant levels with mixed results. In this talk, a mathematical model is used to explore this contested therapy.
