Differences in conformation, size and expression of GLUT3 in PAF activated human donor neutrophils (confocal microscopy). Compared to control neutrophils (left), PAF activated human donor neutrophils (right) became larger, more amoeboid (amorphous) in shape, and demonstrated increased immunostaining for GLUT3 with PAF activation. With PAF activation, the mean diameter of a neutrophil was 1.23 fold larger than control cells (p < 0.002), and the cellular GLUT3 fluorescence was 2.17 fold greater, (p < 0.002), differences that were statistically significant.
