Figure Lengend Snippet: T cell development in WT and lamp2 KO thymic grafts. Representative dot plots of CD4 and CD8 expression within (A) total thymocytes and (B) TCRB + thymocytes in thymic grafts of Nude recipients transplanted with WT (WT-Nu) and lamp2 KO ( lamp2 KO-Nu) ectopic thymus, 8–10 weeks after transplantation. Numbers on the plots indicate the frequencies of the different subsets. Bar graphs in A and B depict the average absolute cellularity of the thymus and the indicated thymocyte subsets in WT-Nu (gray) and lamp2 KO-Nu (blue). In B, ratio of the frequency of SP4:SP8 is shown in WT-Nu and lamp2 KO-Nu, as well in the endogenous thymus. (C) Analysis of peripheral T cells in spleens from WT-Nu and lamp2 KO-Nu mice. Graphs (left) represent the average % and numbers of TCRB + T cells in the spleen. Dot plots show CD44 and SELL/CD62L expression within CD4 and CD8 T cells. Graphs (right) show average cellularity of naïve (SELL/CD62L + CD44 lo ) and effector/memory (SELL/CD62L ± CD44 hi ) CD4 and CD8 T cells. Data represent an average of 3 independent experiments (n = 10 WT and lamp2 KO ectopic thymi). Results in A-C are shown as mean ± SEM. * p < 0.05; ** p < 0.01; *** p < 0.001.
