Glucose transporter 1 in rheumatoid arthritis and autoimmunity.

Knowledge about metabolism of immune cells increased almost exponentially during the last two decades and thereby created the new area immunometabolism. Increased glucose uptake and glycolysis were identified as one of the major drivers in immune cells for rapid adaptation to changes in the microenvironment or external stimuli. These metabolic switches are crucial to generate macromolecules for immune cell proliferation and activation.
