肌肉和脂肪细胞中的GLUT4系统在全身葡萄糖稳态中起重要作用。胰岛素刺激GLUT4从细胞内储存区室移位到细胞表面。这个隔间的性质在很大程度上仍然未知。我们回顾了最近的研究描述的生物起源和分子组成的GLUT4存储隔间,并得出结论,它是隔离的内体和生物合成途径。此外,我们提出的证据表明,GLUT4储存室直接移动到质膜响应胰岛素,因此,类似于神经元中的小突触囊泡。我们建议将GLUT 4储存室称为GLUT 4储存囊泡或GSV。
The GLUT4 system in muscle and fat cells plays an important role in whole-body glucose homeostasis. Insulin stimulates the translocation of GLUT4 from an intracellular storage compartment to the cell surface. The nature of this compartment remains largely unknown. We review recent studies describing the biogenesis and molecular constituents of the GLUT4 storage compartment and conclude that it is segregated from the endosomal and biosynthetic pathways. Further, we present evidence to suggest that the GLUT4 storage compartment moves directly to the plasma membrane in response to insulin and, hence, is analogous to small synaptic vesicles in neurons. We propose that the GLUT4 storage compartment be referred to as GLUT4 storage vesicles or GSVs.
