FIG. 1.

Deletion of CD4⁺/Vβ14⁺ T cells in I/LnJ mice foster nursed on C3H/HeN MMTV⁺ mice. Kinetics of the Vβ repertoire of peripheral CD4⁺ T cells from I/LnJ and C3H/HeN mice foster nursed on C3H/HeN MMTV⁺ females are shown. Five mice were used at each data collection point. Data are expressed as means and standard deviations. I/LnJ f C3H/HeN MMTV⁺, I/LnJ mice foster nursed on viremic C3H/HeN females.
