Cytokines mRNA in bone marrow-derived dendritic cells in asthmatic mouse
Tóm tắt
By inducing and amplifying dendritic cells (DCs) derived from the bone marrow of asthma murine in vitro, cytokines mRNA were expressed, and the functions of DCs were investigated. Cells isolated from murine bone marrow have been cultured with rmGM-CSF and rmIL-4, and the expression of cytokines mRNA was determined by ribonuclease protection assay combined with multi-probe templates. Large numbers of DCs have been obtained from bone marrow, and they expressed interleukin-13 (IL-13), interleukin-9 (IL-9), and interleukin-3 (IL-3) mRNA. Moreover, the level of IL-13 mRNA and IL-9 mRNA expressed by DCs in asthmatic mice was significantly higher than those in the control groups (P<0.05). But, the level of IL-3 mRNA showed no discrepancy between the two groups (P>0.05). DCs are very important in the forming and developing of asthma, which implies that the therapy targeted at DCs will possibly become a new goal.
