Human memory T cells of the bone marrow are resting and maintain long-lasting memory

ABSTRACT: To compare human memory CD4+ T cell subsets in peripheral blood (PB) and bone marrow (BM) of healthy individuals at transcriptional level, we analyzed the global gene expression of ex vivo PB CD69- as well as BM CD69- and CD69+ memory CD4+ T cells from 4 paired PB and BM samples. The gene expression of these subsets was additionally compared to the transcriptional profile of 8 PB samples taken ex vivo or stimulated with phorbol myristate acetate (PMA) and Ionomycin for 3 hours. Three ex vivo memory CD4+ T cell subsets (CD4+CD45RO+CD69+ and CD4+CD45RO+CD69- cells from bone marrow; CD4+CD45RO+CD69- cells from peripheral blood) were isolated from 4 paired bone marrow and blood samples (two males and two females) or from a different cohort of 8 blood samples (3 males and five females).
