I know that the GLUT4 transporter allows for insulin-dependent uptake of glucose in skeletal muscle, liver and adipocytes. I also know that GLUT2 transporters are present in the liver and allow it to absorb glucose in the absence of insulin, and GLUT1/GLUT3 allow glucose to cross the blood-brain barrier and enter neurons.
However in my research I could not find the mechanism for glucose uptake in the remaining tissues of the body (Ex. epithelial tissue, connective tissue). Are there other types of transporters for glucose in these tissues? Surely these other cells also need glucose to survive.
