L-乳酸传统上被认为是一种代谢废物,在哺乳动物中越来越被认为是一种重要的细胞间能量货币。为了能够研究L-乳酸在细胞间穿梭的新作用,我们现在报告了一种用于细胞外L-乳酸的强化绿色荧光基因编码生物传感器。这种名为eLACCO1.1的生物传感器能够在培养的哺乳动物细胞和脑组织中对细胞外L-乳酸进行细胞分辨率成像。L-乳酸是一种重要的胞间能量货币。在这里,作者报告了一种基因编码的生物传感器eLACCO1.1,用于监测细胞外L乳酸;他们使用eLACCO1.1对培养的哺乳动物细胞和脑组织中的细胞外L乳酸进行成像。
l-Lactate, traditionally considered a metabolic waste product, is increasingly recognized as an important intercellular energy currency in mammals. To enable investigations of the emerging roles of intercellular shuttling of l-lactate, we now report an intensiometric green fluorescent genetically encoded biosensor for extracellular l-lactate. This biosensor, designated eLACCO1.1, enables cellular resolution imaging of extracellular l-lactate in cultured mammalian cells and brain tissue. l-lactate is an important intercellular energy currency. Here the authors report a genetically encoded biosensor eLACCO1.1 to monitor extracellular l-lactate; they use eLACCO1.1 to image extracellular l-lactate in cultured mammalian cells and brain tissue.
