Abstract:
OBJECTIVES:Cord blood (CB) transplantation has advantages in terms of incidence and severity of acute graft-versus-host disease (GVHD), while it has disadvantages in terms of infection. Our aim is to elucidate the molecular mechanism underlying the immune response of CB-derived cells during acute GVHD and infection following CB transplantation. METHODS:We examined expression of 69 immune-relating microRNAs in CD4(+), CD8(+), and CD14(+) cells of CB and adult peripheral blood (APB) upon interferon-γ or lipopolysaccharide (LPS) stimulation. RESULTS:Under basal condition, 20 microRNAs showed differential expression between CB and APB. Compared to APB counterparts, six microRNAs (miR-21, miR-22, miR-29a, miR-29b, miR-29c, and let-7c) were underexpressed in at least two cell lineages of CB, while five microRNAs (miR-15b, miR-181a, miR-181c, miR-363, and miR-424) were overexpressed in CD4(+) and CD8(+) CB cells. Upon interferon-γ stimulation, seven microRNAs (miR-29a, miR-29b, miR-34c-5p, miR-132, miR-146a, miR-146b-5p, and miR-155) changed in expression mainly in CD14(+) CB cells, while only two microRNAs (miR-18a and miR-155) changed in expression in CD14(+) CB cells upon LPS stimulation. These results suggest that the mechanisms regulating the expression of such immune-relating microRNAs in CD14(+) CB cells are much more sensitive to proinflammatory stimuli than those in APB CD14(+) cells, which might be related to the poor immunoreactivity of CD14(+) CB cells. CONCLUSIONS:Our results suggest essential roles of specific microRNAs in regulating immune function of CB cells, providing insight into the underlying molecular mechanism.
