Figure 3: The expression of the intestinal homing receptor, α 4β 7 integrin, the peripheral lymph node HR, L-selectin, and the skin HR, CLA, on KLH-specific plasmablasts after two subcutaneous KLH injections given to orally primed or nonprimed volunteers. The data were calculated by counting the proportion of HR positive cells among all cells (the sum of HR positive and negative cells). The data are given as arithmetic means of the percentage of ASC expressing the given receptor ± SD. The numbers of volunteers from whom the data were pooled are indicated under each bar.
