When macrophages are deprived of oxygen: How pathogens are controlled when tissue is deprived of adequate oxygen supply

Infected tissue has a low concentration of oxygen. The body's standard immune mechanisms, which rely on oxygen, can then only function to a limited extent. How does the immune system nevertheless manage to control bacteria under such conditions? Researchers have discovered that fewer metabolites are produced in the citric acid cycle under hypoxic conditions, leading to a reduced rate of reproduction among bacteria in macrophages.
