Positive foods result in upregulation of CD63 in eosinophils to a greater degree than negative foods. a Histogram of CD63 levels on an eosinophil population after exposure to no food, negative food and positive food, showing a shift to the right for the positive foods. b, c and d Histogram of meal fluorescence intensity (MFI) of CD63 for eosinophils, neutrophils and basophils. e Eosinophils from subjects gave a higher CD63 level with positive as compared to negative food items (* P < 0.05). f and g Neutrophils and basophils did not have a higher level of CD63 with positive foods. Ten patients were included and two positive and two negative foods were studied for each patient, resulting in the following sample sizes: “No Food Group” n = 18, “Positive food Group” n = 18, “Negative Food Group” n = 18. Data are represented as mean with SEM
