Dansyl chloride, a skin sensitizer when injected in complete Freund's adjuvant, induced
marked tolerance and no sensitization when applied to the intact skin of guinea pigs.
Application of this chemical to alymphatic skin islands failed to induce tolerance or
sensitization. Lymphatic connections between skin and regional lymph nodes were
essential for the development of immunologic tolerance.
