Molecular phenotypes of cultured T cells from infected deer mice. RNA from cultured T cells was reverse transcribed for PCR to detect the expression of CD4, T-bet, GATA3, and FoxP3. All cells were CD4⁺ and T-bet⁺, whereas only T cells from acutely infected deer mice expressed GATA3. FoxP3 expression was detected in some of the acutely and persistently infected deer mice.
