Abstract The aim of this study was to assess the total IgE levels in the supernatants and cellular components of colostrum from atopic and nonatopic mothers. Immunoglobulin E protein was detected in 34/39 milk samples, with a median level of 0.3 microgram/l. In 13 mothers, IgE protein was also detected in the cellular fraction of colostrum, with a median level of 0.13 microgram/l. Of the total IgE content in breast milk, 5-12\% was transported intracellularly. The total IgE antibody levels were similar in both milk supernatants and cells from atopic and nonatopic mothers. There was a strong relationship between total IgE antibody levels in serum and in breast milk (r = 1.0, P < 0.001), suggesting that IgE antibodies were passively transported from blood into breast milk. The levels of total IgE in human milk are probably too low to have a significant effect on the regulation of the IgE antibody levels in the neonate.
