Nucleoprotein is also a major immunogenetic antigen for SARS; however, several tests have shown that N protein had the reactivity with other coronavirus positive sera. It is therefore an advantage of S protein as recombinant target antigen for SARS serum diagnosis compared with recombinant N protein. Moreover, S protein has been shown to be the major antigenic determinant that induces neutralizing antibodies and protective immunity to SARS-CoV, so it is also important in designing SARS genetic engineering vaccine.

SARS-CoV S 蛋白由1255 个氨基酸组成，体外表达如此大的蛋白很困难，而且表达蛋白的可溶性不高；其次，实验已经证实，全长S 蛋白含有大量无关的表位，致使表达的全长S蛋白对SARS 阳性血清的检出率低于S 蛋白片段；另外作为疫苗研究，S 蛋白上大量无关表位作为异体蛋白进入体内，会引发机体的过度免疫反应，这也是SARS-CoV 可能的致病机理之一。

Recent studies show that the binding of HCV enveloped E2 protein to CD81 molecule leads to the lymphocyte functional disorders, which may play an important role in HCV chronic infection and have closed relation with B cell lymphadenoma and cryoglobulinemia. Associated with formation of HCV infection is hard to induce neutralizing antibody and thus leading to chronic infection.

最近的一些研究发现，HCV包膜E2蛋白与CD81分子结合所致免疫细胞的功能紊乱也可能是HCV慢性感染的重要原因，并且与B细胞淋巴瘤以及冷球蛋白血症具有重要相关性。

Mechanistically, CYR61 enhanced bmp-2 mRNA and protein expression in time- and dose-dependent manners, and osteoblast migration, proliferation, and differentiation abilities were significantly inhibited by BMP-2 neutralizing antibody.

实验结果发现，将CYR61重组蛋白处理造骨细胞，观察到随著CYR61处理浓度增加，可以促进造骨细胞的增生、移动；随著处理时间的延长可以促使细胞矿物质化。

The neutralizing activity of these antibodies and IgG fractions is acquired through post-translational modifications, through opsonization of virus particles into macrophages and immature dendritic cells, or through expression of antibodies on the surface of HIV-1-susceptible cells.

这些抗体或IgG片段的中和活性可以通过抗体分子翻译后的修饰，或介导巨噬细胞和未成熟树突状细胞的对病毒颗粒的调理作用，或者通过表达在HIV易感细胞表面来体现。

Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces. Thus, Na-clays are ine_ective sorbents for small organic molecules. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds. Textile dyes represent a relatively large group of organic chemicals. In an HDTMA-bentonite-dye system it is possible that adsorption may be enhanced by the hydrophobic interaction between the adsorbed dye molecule and HDTMA-bentonite.

O组给予亲水的性质到矿物表面，因为这水是吸附在这些表面，和大的有机化合物不能比有坚强的为了吸附位置在泥土表面，因而，Na—泥土是ine_ective吸附剂为了小的分子，希，它是可能的到更改的表面属性，泥土非常在抵销anionic层硅酸盐在用的结构 Positively负荷的物种例如alkylammonim离子，在mod i_ed形状，泥土表面可能变成organophilic和互相作用坚强地有机化合物，织物染料表现相关的大的组化学的，在HDTMA—斑脱土—染料系统它是可能的那吸附可能是提高在交互作用在中间吸附染料分子和HDTMA—斑脱土，interlamellarHDTMA的间隔—斑脱土是获得在substracting泥土层从的厚度实验上坚决的基础的间隔（d001）。

The experimental results show that the interaction between polysilicic acid characterized negative charge and hydrolyzed aluminum species results in the decrease in the charge-neutralizing ability of PASC, in comparison with PAC.

研究结果表明，在 PASC 中，由于带负电荷的聚硅酸与铝水解聚合产物间的相互作用，使得 PASC 的电中和能力较 PAC 有所下降，其下降程度与 PASC 的碱化度和 Al/Si 摩尔比密切相关，B 值和 Al/Si 摩尔比越小，则 PASC 的电中和能力就越弱。
