T cell cytokine production in response to raw, pasteurized CM and heated CM-containing food extracts. (A) A bar graph showing IL-5 and IFNγ production in response to re-stimulation with raw, pasteurized CM extract after a two-week expansion culture (allergic subjects n = 20, non-allergic subjects n = 14). (B) Bar graphs showing IL-5 (left panel) and IFNγ (right panel) production in response to re-stimulation with raw, pasteurized CM (black), custard (blue), baked cheese (red) and muffin (green) extracts after two-week expansion culture (n = 10). Bars represent medians, with error bars showing interquartile means. Statistical analysis was performed by Mann-Whitney test (two-tailed), p < 0.05 considered significant.
