项目摘要
We have investigated the cellular localization of the marine sponge-derived excitatory amino acid dysiherbaine (DH), and found that DH-like immunoreactivity was densely located in the large (10 μm) globular cells. On the basis of 18S rDNA sequence analysis it was shown that this cell belongs to the sponge itself, however, results from fluorescent microscopy and immunohistochemistry using anti-phycobilin antibody indicated that this cell contains phycobilin, a photosynthetic pigment of cyanobacteria. Although number of histological observations of D.herbacea are available in literature, cells with this morphological or biochemical characteristics have never been reported.A comparison of the extract of D.herbacea collected in various regions in Yap, Palau, or Guam indicated that DH is unique to the Yap specimen. Among the Yap specimens, however, concentration of DH varied significantly. Interestingly, all the Yap specimens we have examined so far contained the globular cells regardless of the DH concentration, but the cells were not observed in the sponges collected in Palau or Guam. As expected, the globular cells of the DH-free Yap specimen were unlabeled by the antibody. These findings suggested that DH was produced and stored in the "globular cells" which is a previously unidentified type of sponge cells unique to Yap specimen of D.herbacea, and biosynthesis of DH in this cell might be controlled by some unknown factors.
我们研究了海绵源性兴奋性氨基酸dysiherbaine(DH)的细胞定位,发现DH样免疫反应物密集地位于大的(10 μm)球形细胞中。18S rDNA序列分析的基础上,它表明,该细胞属于海绵本身,然而,荧光显微镜和免疫组化使用抗藻胆素抗体的结果表明,该细胞含有藻胆素,蓝细菌的光合色素。虽然文献中有大量的组织学观察,但具有这种形态学或生化特征的细胞从未被发现。比较在雅普、帕劳或关岛不同地区采集的D.herbacea提取物表明,DH是雅普标本所特有的。然而,在雅普标本中,DH的浓度变化很大。有趣的是,到目前为止,我们检查的所有雅普标本都含有球状细胞,而不管DH浓度如何,但在帕劳或关岛收集的海绵中没有观察到这种细胞。正如预期,无DH雅普标本的球状细胞未被抗体标记。这些结果表明,DH是在雅普标本特有的海绵细胞“球状细胞”中产生和储存的,其生物合成可能受某些未知因素控制。
