亲亲相隐原则的法理探析及其在当代中国命运之检讨

亲亲相隐在中国古代作为体现儒家思想、维护封建家长制统治的一项法律制度，在新中国已作为封建糟粕被摒弃。但从现代法治社会的眼光审视，其对社会最基本的人伦血缘关系的承认与关怀，仍具有独立存在的价值。前瞻其在中国未来之命运，应在刑事立法中占有一席之地，它表现为一定的亲属间相互享有作证豁免特权，但必须对内容进行一定的整合。

BFA对小鼠脾脏T淋巴细胞增殖活性影响的初步研究

为了了解BFA对动物免疫细胞增殖的影响,以伴刀豆球蛋白(Con A)作为阳性药,用MTT法检测了BFA对小鼠脾脏T淋巴细胞增殖活性的影响.实验结果显示,极低浓度的BFA对小鼠脾脏T淋巴细胞增殖活性就有显著的促进作用,其促进效果与Con A相似.且不同浓度的BFA的促进作用在一定范围内显示正量效关系.在过高浓度的BFA作用下,虽然量效关系不明显,但未出现抑制作用.证明BFA在淋巴细胞转化阶段对于细胞免疫有显著的增强作用.而且BFA的毒性极小,大量使用不易出现毒副作用.     

Antigen presentation by CD1 molecules and the generation of lipid-specific T cell immunity

It is now well demonstrated that the repertoire of T cells includes not only cells that recognize specific MHC-presented peptide antigens, but also cells that recognize specific self and foreign lipid antigens. This T cell recognition of lipid antigens is mediated by a family of conserved MHC class I-like cell surface glycoproteins known as CD1 molecules. These are specialized antigen-presenting molecules that directly bind a wide variety of lipids and present them for T cell recognition at the surface of antigen-presenting cells. Distinct populations of T cells exist that recognize CD1-presented lipids of microbial, environmental or self origin, and these T cells participate in immune responses associated with infectious, neoplastic, autoimmune and allergic diseases. Here we review the current knowledge of the biology of the CD1 system, including the structure, biosynthesis and trafficking of CD1 molecules, the structures of defined lipid antigens and the types of functional responses mediated by T cells specific for CD1-presented lipids.     

Chitotriosidase: the yin and yang

The enzyme chitotriosidase (ChT), the human analogue of chitinases from non-vertebrate species, is one of the most abundant and indicative proteins secreted by activated macrophages. Its enzymatic activity is elevated in serum of patients suffering from Gaucher’s disease type 1 and in some other inherited lysosomal storage disorders, as well as in diseases in which macrophages are activated. The last decade has witnessed the appearance of a substantial number of studies attempting to unravel its cellular functions, which have yet not been fully defined. A great deal of progress has been made in the study of the physiological roles of ChT. This review is looks at the key areas of investigations addressed to further illuminate whether ChT activation might have different functional meanings in various diseases.

<Emphasis Type="Italic">Drosophila melanogaster</Emphasis> innate immunity: an emerging role for peptidoglycan recognition proteins in bacteria detection

Over the past years, parallel studies conducted in mammals and flies have emphasized the existence of common mechanisms regulating the vertebrate and invertebrate innate immune systems. This culminated in the discovery of the central role of the Toll pathway in Drosophila immunity and in the implication of Toll-like receptors (TLRs)/interleukin-1(IL-1) in the mammalian innate immune response. In spite of clear similarities, such as shared intracellular pathway components, important divergences are expected between the two groups, whose last common ancestor lived more than half a billion years ago. The most obvious discrepancies lie in the mode of activation of the signalling receptors by microorganisms. In mammals, TLRs are part of protein complexes which directly recognize microbe-associated patterns, whereas Drosophila Toll functions like a classical cytokine receptor rather than a pattern recognition receptor. Recent studies demonstrate that members of the evolutionarily conserved peptidoglycan recognition protein family play an essential role in microbial sensing during immune response of Drosophila.Received 26 June 2003; received after revision 29 July 2003; accepted 25 August 2003     

小鼠口服猪卵透明带DNA避孕疫苗pVAX1-pZP3a的抗生育研究

目的：评价口服卵透明带DNA避孕疫苗pVAX1-pZP3a壳聚糖纳米微粒诱发的黏膜免疫反应、抗生育作用和对卵巢结构的影响，探讨用黏膜免疫避免卵透明带抗原免疫引起卵巢功能紊乱的可行性。方法：制备pVAX1-pzP3a壳聚糖纳米微粒，10只昆明系小鼠口服免疫，第3周和第6周分别加强免疫一次，剂量为O．5ml／只，含pVAXl-PZP3aDNA 50μg；对照组10只雌小鼠口服相同剂量不含pVAX1-pZP3a的壳聚糖。免疫前和免疫后隔周取小鼠血清、阴道冲洗液，用ELIASA法检测抗pzP3 IgA和IgG。首次免疫后第12周雌雄合笼交配，统计雌鼠怀孕情况；解剖取出双侧卵巢，制作石蜡切片，光镜观察卵巢病理学变化。结果：免疫组80％小鼠的血清和50％小鼠的阴道冲洗液可检测到抗pzP3 IgA，反应强度与持续时间有明显的个体差异；免疫组5只小鼠未怀孕，对照组全部怀孕，抗生育效果与合笼时抗pzP3 IgA反应有关；免疫组未怀孕小鼠卵巢组织结构与免疫组怀孕小鼠及对照组小鼠无差别。结论：口服pVAX1-pZP3a壳聚糖纳米微粒免疫小鼠能诱发生殖道黏膜免疫反应，发挥抗生育作用，对卵巢组织结构没有影响。黏膜免疫是克服卵透明带抗原免疫引起卵巢功能紊乱的一种值得深入研究的方法。
