Aim: The aim of the study was to investigate the level of cytokines in cultures of cow’s milk protein- stimulated peripheral blood mononuclear cells of patients with cow’s milk protein allergy. Material and Methods: Eleven children with cow’s milk protein allergy and 11 non-allergic controls were studied. Their peripheral blood mononuclear cells were cultured alone and in the presence of cow’s milk α-lactalbumin; β-lactoglobulin; αS 1, αS 2, β, and κ-casein fraction mixtures; and a cow’s protein mixture from whole milk. Production of cytokines, tumor necrosis factor-α, interleukin-10, and interleukin-12 were determined in culture supernatants. Results: In cow’s milk protein-stimulated peripheral blood mononuclear cell cultures of children with cow’s milk protein allergy, tumor necrosis factor-α, interleukin-10, and interleukin-12 production was significantly higher than in non-allergic controls (p<0.05). No difference in cytokine production was found between cultures obtained from unstimulated peripheral blood mononuclear cell cultures of both cow’s milk protein allergy and non-allergic controls. Conclusions: The findings of this preliminary study align with data from the literature suggesting that the investigation of tumor necrosis factor-α, interleukin-10, and interleukin-12 in cow’s milk protein-stimulated peripheral blood mononuclear cell cultures of children may be taken in further consideration to explore whether they might have a predictive role for cow’s milk protein allergy. Further studies are therefore needed to extensively investigate this issue.

Abstract

Aim: The aim of the study was to investigate the level of cytokines in cultures of cow’s milk protein- stimulated peripheral blood mononuclear cells of patients with cow’s milk protein allergy. Material and Methods: Eleven children with cow’s milk protein allergy and 11 non-allergic controls were studied. Their peripheral blood mononuclear cells were cultured alone and in the presence of cow’s milk α-lactalbumin; β-lactoglobulin; αS 1, αS 2, β, and κ-casein fraction mixtures; and a cow’s protein mixture from whole milk. Production of cytokines, tumor necrosis factor-α, interleukin-10, and interleukin-12 were determined in culture supernatants. Results: In cow’s milk protein-stimulated peripheral blood mononuclear cell cultures of children with cow’s milk protein allergy, tumor necrosis factor-α, interleukin-10, and interleukin-12 production was significantly higher than in non-allergic controls (p<0.05). No difference in cytokine production was found between cultures obtained from unstimulated peripheral blood mononuclear cell cultures of both cow’s milk protein allergy and non-allergic controls. Conclusions: The findings of this preliminary study align with data from the literature suggesting that the investigation of tumor necrosis factor-α, interleukin-10, and interleukin-12 in cow’s milk protein-stimulated peripheral blood mononuclear cell cultures of children may be taken in further consideration to explore whether they might have a predictive role for cow’s milk protein allergy. Further studies are therefore needed to extensively investigate this issue.
