Outline of Final Research Achievements

Concerning the relationship between resin monomers (RMs) and allergies, we found the followings. (i) 2－Hydroxyethyl metacrylate (HEMA) and methyl methacrylate (MMA), both typical RMs, act as adjuvants that promote nickel (Ni)-allergy at the steps of both the sensitization and elicitation. (ii) RMs also promoted the allergies induced by hydroquinone (widely used as an inhibitor of RM-polymerization) and oxazolone (a hapten widely used in experiments). These findings strongly suggest that what were previously thought of as “RM-allergies” might include allergies caused by antigens other than RMs. From now, RMs should be recognized not only as antigens but also as adjuvants that promote allergies induced by other antigens.
