The ability of exogenous proteins to cause respiratory and gastrointestinal
allergy, and sometimes systemic anaphylactic reactions, is well known. What
is not clear however, are the properties that confer on proteins the
ability to induce allergic sensitization. With an expansion in the use of
enzymes for industrial applications and consumer products, and a
substantial and growing investment in the development of transgenic crop
plants that express novel proteins introduced from other sources, the issue
of protein allergenicity has assumed considerable toxicological
significance. There is a need now for methods that will allow the accurate
identification and characterization of potential protein allergens and for
estimation of relative potency as a first step towards risk assessment. To
address some of these issues, and to review progress that has been made in
the toxicological investigation of respiratory and gastrointestinal allergy
induced by proteins, a workshop, entitled the Toxicology of Protein
Allergenicity: Prediction and Characterization, was convened at the 37th
Annual Conference of the Society of Toxicology in Seattle, Washington
(1998). The subject of protein allergenicity is considered here in the
context of presentations made at that workshop.
