title: The production of contact sensitivity by the injection into the footpads of recipients of the lymph node cells from mice 1 day after painting the skin with contact sensitizing agent: requirement for matching at the major histocompatibility complex between donor and recipient mice.
abstract: Donor mice were painted on the skin of the abdomen with the contact sensitizing agent, oxazolone. One day later 2-5 x 10(6) cells from the regional lymph nodes were injected into the footpads of recipient mice. Contact sensitivity was detected 6 days later by challenging the ears of the recipients and measuring the increase of thickness at 24 h. Good contact sensitivity was obtained when CBA cells were injected into CBA mice and BALB/c cells injected into BALB/c mice; the injection of BALB/c (H-2d) cells into CBA (H-2k) mice and vice versa failed to give rise to contact sensitivity. Hybrid F1 cells gave intermediate responses. The contact sensitivity caused by the injection of small numbers of lymph node cells into the footpad is interpreted as a mode of active immunization and the present results show that this only occurs when there is genetic matching at the major histocompatibility complex between the donor and the recipient mouse.
