Cell transfer number affects the Tg T cell phenotype.

<p>Different numbers of a 1:1 mixture of TRBV13-2:TRBV13-1 cells were transferred 1 day prior to RSV infection. On day 6 post-infection, we assessed the phenotype of the transferred Tg T cells based on expression of CD62L, CD127, and KLRG1. The percentage of Tg CD8+T cells of each phenotype in the 10⁴ transfer group are in the lungs (A) and MLN (B) are shown. The CD127^lo, CD62L^lo; KLRG1^lo to CD127^hi, CD62L^lo; KLRG-1 ^lo ratio in the lungs (C) and MLN (D) was determined. Bars represent mean±SEM.
