Abstract

Immunometabolism emerged as a new frontier of knowledge in search of integration between the historically distinct disciplines of Metabolism and Immunology. Within this context, mitochondria play a central role. Mitochondria are constantly adapting their morphology to meet the cell's energy requirements. This process is regulated either by elongation (fusion) or fragmentation of mitochondria (fission). While fusion is related to a higher rate of oxygen consumption and an alternatively activated profile, fission is both related to the intracellular transport of this organelle as well as to greater mitochondrial dysfunction and production of reactive oxygen species. However, how the mitochondrial dynamics modulates the activation of macrophages is not yet fully elucidated. Thus, we aim to determine how changes in the machinery that regulates mitochondrial dynamics modulate macrophage activation. (AU)
