Proliferation is dependent on transfer number, but does not differ between TRBV 13–1 and TRBV13-2.

<p>(A and B) 1:10 dilutions of a 1:1 ratio of TRBV13-1:TRBV13-2 cells were transferred 1 day prior to RSV infection. Four days post-infection, the percentage of proliferating cells in the lung (A) and MLN (B) were identified by <i>in vivo</i> incorporation of BrdU during a two-hour incubation. <b>(</b>C and D) violet labeled TRBV13-1 and TRBV13-2 were co-transferred into CB6F1 mice prior to infection with RSV. Proliferation profiles of TRBV13-1and TRBV13-2 (C) in the MLN were evaluated at day 4 post-infection and percentage of dividing cells was determined (D).
