Sugar or Fat?-Metabolic Requirements for Immunity to Viral Infections

Front Immunol. 2017 Oct 16;8:1311. doi: 10.3389/fimmu.2017.01311. eCollection 2017.


The realization that an intricate link exists between the metabolic state of immune cells and the nature of the elicited immune responses has brought a dramatic evolution to the field of immunology. We will focus on how metabolic reprogramming through the use of glycolysis and fatty-acid oxidation (sugar or fat) regulates the capacity of immune cells to mount robust and effective immune responses. We will also discuss how fine-tuning sugar and fat metabolism may be exploited as a novel immunotherapeutic strategy to fight viral infections or improve vaccine efficacy.

Keywords: HIV; T cells; glycolysis; immunometabolism; mTOR; viral infection.
