目的:观察日本血吸虫可溶性虫卵抗原(SEA)对体外培养的大鼠腹腔巨噬细胞(PMCs)中TNF-α活化及表达的影响。方法:体外培养大鼠PMCs,利用苏木素-伊红染色( HE染色)、免疫细胞化学染色( IHC)、RT-PCR以及放免法,对SEA作用后的大鼠PMCs形态变化和TNF-α表达进行观察;同时,制备SEA活化腹腔巨噬细胞条件培养基( SEA-MCM),利用MTT比色法和3H-脯氨酸掺入法,对经过SEA-MCM作用后的HSC-T6细胞增殖及胶原合成结果进行检测。结果:①大鼠PMCs在LPS(10 mg/L)和SEA(10 mg/L)分别作用3 h、6 h和9 h后,可以使PMCs活化增加,并促进大鼠PMCs TNF-α蛋白表达( P<0.05);②LPS(10 mg/L)和SEA(10 mg/L)分别作用6 h,大鼠PMCs TNF-αmRNA表达增加( P<0.05);③LPS(10 mg/L)和SEA(10 mg/L)分别作用3 h、6 h和9 h,培养上清中TNF-α含量高于阴性对照组(P<0.05);6 h和9 h组均高于3 h组(P<0.05),6 h和9 h组间无明显差别(P>0.05);④SEA-MCM促进HSC-T6细胞增殖和胶原合成(P<0.05)。结论:体外实验证实SEA与LPS在活化大鼠PMCs、促进TNF-α表达和分泌中有相似的作用,这可能与SEA活化大鼠PMCs能明显促进HSC-T6细胞增殖和胶原合成有关。

Objective:To observe the effect of soluble egg antigen(SEA) on TNF-αexpression in rat peritoneal macrophages in vitro and proliferation and collagen synthesis of HSC-T6 cells.Methods:Rat peritoneal macrophages were harvested via irrigation of the peritoneal cavity,and cultured in vitro.The effect of SEA on the expression of TNF-αin the rat peritoneal macrophages was observed after staining of the cells with HE and immunocytochemistry ,RT-PCR and radiommunity.SEA-MCM was prepared,and MTT colorimetric assay and 3H-proline incorporation were performed to detect the proliferation and collagen synthesis of HSC-T6.Results:①At 3,6 and 9h,the expression of TNF-αin the SEA and LPS group was significantly higher than that in the con-trol treated with RPMI1640(P<0.05);②The level of TNF-αin the supernatant was also significantly higher than that in the control treated RPMI1640 (P<0.05);③After exposure to SEA or LPS for 3,6 and 9 h,the expression of TNF-αmRNA of peritoneal macrophages in the SEA and LPS group was significantly higher than that in the control after treatment with RPMI1640(P<0.05);④SEA-MCM significantly promoted the proliferation and collagen production of HSC-T6 cells (P<0.05).Conclusion:SEA,functioning similarly with LPS,may have the effect to induce rat peritoneal macrophages activa-tion and promote expression and secretion of TNF-α,which is possibly related to the capacity of SEA that is capable of promoting the proliferation and col-lagen production of HSC-T6 in vitro.
