Résumé
FACS analysis of either CD4 or CD8 depleted thymocytes revealed, that in adult Mlsa mice among CD4+ or CD8+ subpopulation of mature T cells V beta 6+ cells were absent. In contrast neonatal Mlsa mice had CD4+ V beta 6+ cells that rapidly decreased after day 4. On thymus cryosections of neonatal DBA/2 (Mlsa) mice V beta 6+ cells were found both in the cortex and the medulla of the thymus, in addition V beta 6+ cells were also detected in lymph nodes. After day 7-8 V beta 6+ cells disappeared from the medulla and the periphery. In the adult thymus only dull staining V beta 6+ cells were present in the cortex. Comparison of the fluorescence intensities of V beta 6 staining thymocytes from neonatally with Mlsa spleen cells tolerized mice with that of untreated BALB/c controls showed a significant decrease in T cell receptor density. Neonatal V beta 6+ T cells could be shown to be autoreactive against Mlsa, this reactivity declined at about the same time when the stimulatory capacity of Mlsa was established and could be first shown on day 4.
