Does chemical modification of birch allergen extract lead to a reduction in allergenicity as well as immunogenicity?
The reduced histamine release observed for allergoid preparations may be at the expense of immunological efficacy because the chemical modifications lead to a clear reduction in T cell activation and the ability to induce allergen-specific IgG antibody responses.
Adsorption and neutralization by Talcid of all H. pylori secreted proteins may explain, at least in part, the ulcer-healing action of this drug.
