CHAPTER 34Circulation Through Special Regions 585
- A baby boy is brought to the hospital because of convulsions. In
the course of a workup, his body temperature and plasma glu-
cose are found to be normal, but his cerebrospinal fluid glucose
is 12 mg/dL (normal, 65 mg/dL). A possible explanation of his
condition is
A) constitutive activation of GLUT 3 in neurons.
B) SGLT 1 deficiency in astrocytes.
C) GLUT 5 deficiency in cerebral capillaries.
D) GLUT 1 55K deficiency in cerebral capillaries.
E) GLUT 1 45K deficiency in microglia.
