Randomized Controlled Trial
Determination of in vivo dose response and allergen-specific T cells in subjects contact-sensitized to squaric acid dibutyl ester.
Squaric acid dibutyl ester (SADBE) is a known contact sensitizer, but dose-response data are not defined. ⋯ This study establishes the in vivo dose-response characteristics of immune reactivity to SADBE and antigen-specific T-cell reactivity.
