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.
