Effects of bone marrow mesenchymal stem cells on the serum levels of interleukin-4 and interleukin-12 in chronic asthmatic mice
摘要
Abstract
BACKGROUND: Previous studies have demonstrated that anti-inflammatory actions of bone marrow mesenchy (BMSCs)couldameliorate severity of acute lung injury.However,only a few studies have addressed BMSCs transplantation for asthma.OBJECTIVE: To study the effect of allogeneic BMSCs transplantation on the serum levels of interleukin-12 (IL-12) and IL-4 in chronic asthmatic mice.METHODS: Forty female BALB/c mice were equally randomized into four groups. Mice of normal control and BMSCs control groups received PBS sensitization to arouse mice. On day 21 before suscitation, PBS or BMSCs (30 μL) were injected via the intratracheal injection. Mice of asthma model and BMSCs treatment groups were used to establish chronic asthma using chicken ovalbumin. On day 21 before suscitation, PBS or BMSCs (30 μL) were injected via the intratracheal injection. Serum inflammatory factor levels were measured in mice of each group using enzyme linked immunosorbent assay.RESULTS AND CONCLUSION : There were a great number of inflammatory cell infiltrations around airway and vessel, in conjunction with epithelial proliferation and partial breakage and defluvium, patchy airway occlusion by hyperviscous mucus and hypertrophy and hyperplasia of airway smooth muscle in the asthma model group. However, there was no obvious inflammatory cells infiltration in the airway and airway remodeling both in normal control group and BMSCs control group. Airway inflammation and airway remodeling were significantly relieved in the BMSCs treatment group. Compared to the normal control group and BMSCs control group, low level of IL-12 and high levels of IL-13 and IL-4 were present in the asthma model group. Transplantation of BMSCs significantly elevated level of IL-12 and decreased level of IL-4 in serum. Results suggest that BMSCs for asthma can relieve airway inflammation and airway remodeling by decreasing IL-4 levels and increasing IL-12 levels.关键词
