WebFurthermore, both neurons and astrocytes have been shown to express MCT proteins, suggesting that the lactate shuttle may be involved in brain metabolism. Astrocytes express MCT4, a low affinity transporter for lactate (Km = 35mM), suggesting its function is to export lactate produced by glycolysis. WebJan 11, 2024 · Astrocytes play key roles in the regulation of brain energy metabolism, which has a major impact on brain functions, including memory, neuroprotection, resistance to oxidative stress and homeostatic tone. Energy demands of the brain are very large, as they continuously account for 20–25% of the whole body’s energy consumption. Energy supply …

WebLactate in the Brain Lactate is usually considered to be a metabolite of glycolysis in the body under hypoxic conditions. Under normal physiological conditions, aerobic respiration occurs in the cytoplasmic matrix and mitochondria. The first stage of glycolysis generates pyruvate and a small amount of adenosine triphosphate (ATP). WebOct 28, 2016 · Lactate is considered an important metabolite in the human body, but there has been considerable debate about its roles in brain function. Research in recent years has suggested that lactate from astrocytes may be crucial for supporting axonal function, especially during times of high metabolic demands or hypoglycemia.
