Suppressor macrophages induced by the continuous invasion of tumor cells and parasites, which can acquire an ability in vitro to kill or inhibit tumor cells and inhibit the activity of T, B lymphocytes and NK cells, have been indicated. We have developed a procedure previously to modulate the suppressor macrophages by bacterial lipopolysaccharide (LPS). The modulated macrophages remained and even enhanced the ability to inhibit tumor growth and to up-regulate or enhance the activities of T, B lymphocytes and...

Suppressor macrophages induced by the continuous invasion of tumor cells and parasites, which can acquire an ability in vitro to kill or inhibit tumor cells and inhibit the activity of T, B lymphocytes and NK cells, have been indicated. We have developed a procedure previously to modulate the suppressor macrophages by bacterial lipopolysaccharide (LPS). The modulated macrophages remained and even enhanced the ability to inhibit tumor growth and to up-regulate or enhance the activities of T, B lymphocytes and NK cells in vitro. However, the mechanisms of macrophage modulation by LPS are unknown. This investigation was designed to analyze the regulation of PKC activity and to characterize the isoforms of PKC during macrophage modulation by using Western blot and endogenous substrate phosphorylation (PKC-DESP). In

利用免疫印迹技术及内源性底物磷酸化方法,我们研究了在巨噬细胞的信号传递中起重要作用的PKC同功酶的分布及其在免疫调变剂LPS的刺激下产生的激活和转位。在未激活的巨噬细胞中,PKC-β的含量高于PKC-α和ε,它和PKC-α的分布均是胞质中大于胞膜。以PMA为阳性对照,结果提示LPS介导的抑制性巨噬细胞兔疫调变机制中涉及到了PKC-α和PKC-ε从胞质到膜组份的转让而不是PKC-β(PKC-βⅠ或βⅡ)的转位。应用PKC-依赖的内源性底物磷酸化的分析,结果说明胞质中55 kDa和74 kDa蛋白质磷酸化条带的减弱和膜组份中的类似蛋白质(PMA与LPS的刺激有不同的反应)磷酸化强度的增加,与PKC的转位有着相同的时间梯度。这结果提示在LPS介导的免疫调变信号传递通路中,PKC-α和PKC-ε可能介导了信号的传导及放大。

The activities of three antioxidant enzymes ( SOD, POD, CAT ) in different stages of somatic embryogenesis was determined. The effect of the different concentrations of exogenous H 2O 2 on somatic embryogenesis was determined. The change of SOD activity is contrary to the change of POD and CAT activity in somatic embryogenesis. The contents of H 2O 2 raised can greatly enhance the frequency of in somatic embryogenesis under the influence of three antioxidant enzymes. So it is suggested that H 2O 2 may...

The activities of three antioxidant enzymes ( SOD, POD, CAT ) in different stages of somatic embryogenesis was determined. The effect of the different concentrations of exogenous H 2O 2 on somatic embryogenesis was determined. The change of SOD activity is contrary to the change of POD and CAT activity in somatic embryogenesis. The contents of H 2O 2 raised can greatly enhance the frequency of in somatic embryogenesis under the influence of three antioxidant enzymes. So it is suggested that H 2O 2 may act as a “messenger substance”, contribute to gene expression through signal transfer system, and induce embryogenesis . In addition, the frequency of somatic embryogenesis was the highest when the callus was treated with 200 μmol / L H 2O 2.

以药用植物枸杞愈伤组织为材料诱导体细胞胚胎发生,在体细胞胚胎发生过程中的不同发育时期取样,分别测定了SOD,POD和CAT3种抗氧化酶的活性变化,以探讨细胞分化及体细胞胚发生过程中氧自由基代谢水平的变化.另外,在分化培养基中加入不同浓度的H2O2,以探讨氧化胁迫对细胞分化及体细胞胚发生的影响.经测定发现,在体细胞胚发生过程中,SOD活性变化趋势与POD和CAT活性的变化趋势正好相反,推测可能是H2O2通过细胞的信号传递系统影响基因的表达,从而诱导胚的发生.通过在分化培养基中加入H2O2发现,一定浓度的H2O2(200μmol/L)可大大提高愈伤组织中体细胞胚的发生频率,比较发现,在加入200μmol/LH2O2的分化培养基中体细胞胚的发生频率是对照(不加H2O2)组的2倍左右.以上结果表明,H2O2对细胞分化及体细胞胚发生有促进作用.
