Avian mitochondrial glutamine metabolism.
Intact avian liver mitochondria were shown to synthesize glutamine from glutamate in the absence of exogenous ATP and ammonia. With L-[U-14C]glutamate as the substrate, there was an approximate 1:1 stoichiometry between glutamate deaminated (as measured by the release of 14CO2 due to alpha-keto-[14C]glutarate oxidation) and glutamate amidated. With L-[15N]glutamate as the substrate, the isolate...
متن کاملMetabolism Supports Macrophage Activation
Macrophages are found in most tissues of the body, where they have tissue- and context-dependent roles in maintaining homeostasis as well as coordinating adaptive responses to various stresses. Their capacity for specialized functions is controlled by polarizing signals, which activate macrophages by upregulating transcriptional programs that encode distinct effector functions. An important con...
متن کاملMacrophage Hydroxy - Eicosatetraenoic Acid Metabolism
Mouse resident macrophages are potent sources of arachidonic acid (20:4) 1 metabolites generated via both the cyclooxygenase and lipoxygenase pathways (1-5). The phospholipids of this cell are highly enriched with 20:4, and upon appropriate membrane stimulation, up to 50% of endogenous 20:4 is released and metabolized to a mixture of prostaglandins, hydroxy-eicosatetraenoic acids (HETEs), and l...
متن کاملMetabolism Fine-tunes Macrophage Activation
C ells continually monitor the availability of nutrients and alter their activities and metabolism accordingly. Immune cells are no exception (O’Neill and Pearce, 2015). Macrophages are important immune cells that perform many roles – they are, for example, involved in development and wound repair – but they need to be activated before they can carry out their functions. For years it was though...
متن کاملCholesterol Metabolism in the Macrophage
Phagocytosis of cholesterol-containing particles resulted in the formation of an intralysosomal cholesterol compartment. Cholesterol was excreted out of the macrophage with a single exponential rate which depended on the concentration of acceptor lipoproteins in the medium. Exchange kinetics performed on cells which had ingested particulate cholesterol suggested that excretion occurred by the s...
