The purpose

Bovine β-lactoglobulin (Bos d 5) is an allergen from cow's milk with relevance to human health. We employed β-lactoglobulin polymerized using microbial transglutaminase as a model of study to identify whether protein polymerization could reduce in vivo allergenicity and maintain in vitro and ex vivo immunoreactivity for the purpose of producing a suitable molecule for use in tolerance-induction protocols. Based on previous protocols applied in mice and children, we performed in vivo challenges (using a skin prick test) with native and polymerized β-lactoglobulin in adult patients with an IgE-mediated allergy to Bos d 5. In vitro humoral immunoreactivity was analyzed using immunoblotting. Cell-mediated immunoreactivity was analyzed using ex vivo challenges with native and polymerized β-lactoglobulin monitored by leukocyte adherence inhibition tests. The study hypothesis is to identify a decrease on beta-lactoglobulin immunoreactivity after polymerization.
