Chronic hepatitis B is a major health burden worldwide. In addition to the recent progress in antiviral treatment, therapeutic vaccination is a promising new strategy for the control of chronic hepatitis B. On the basis of the major specific and non-specific immune dysregulations and defects in chronic hepatitis B patients, this paper presents the peptide and protein-based, DNA-based, cell-based, and antigen-antibody-based therapeutic vaccines, which have undergone clinical trials. The advantages, disadvantages, and future perspectives for these therapeutic vaccines are discussed.

研制了抗原-抗体复合物型乙肝治疗性疫苗。用小鼠实验证明这一治疗性疫苗的作用机理为:通过复合物中抗体Fc段与抗原呈递细胞表面的Fc受体结合,促进了细胞摄取抗原。复合物中的抗原经呈递后可比单纯抗原更有效地激活T细胞增殖,释放更多的γ-干扰素和白细胞介素-2,属TH1类型应答。复合物可在小鼠中诱生较单纯抗原诱生的抗-HBs高10倍以上。复合物还可诱生更强的细胞免疫,表现为经特异的抗原刺激后,γ-干扰素的mRNA量增多。还发现复合物可在对HBsAg低应答鼠系中(B 10.S)诱生与正常应答鼠相当的抗体效价。在HBsAg阳性转基因鼠中,复合物可使部分鼠的HBsAg转为阴性,并可产生抗-HBs,反映这一疫苗具有疗效。为制备人用乙肝治疗性疫苗建立了用重组酵母菌表达的HBsAg与人高效价抗乙肝免疫球蛋白组建治疗性疫苗的工艺,以及产品标化及效力的参比实验技术。

CD176 (Thomsen-Friedenreich antigen) is a tumor-associated carbohydrate epitope (glycotope) functionally involved in blood spread and liver metastasis of cancer cells by mediating the adhesion of cancer cells to endothelial cells and hepatocytes, respectively. CD176 could be a promising target for antitumor immunotherapy. We applied B lymphocytes obtained from mice immunized with CD176 antigen and constructed a phage display library. A positive clone of CD176 single-chain variable antibody fragment (scFv) was successfully screened from this library. The CD176 scFv was expressed in Escherichia coli and purified. The purified scFv can bind to the natural CD176 expressed on the surface of cancer cells. Furthermore, the CD176 scFv inhibits the adhesion of CD176+ cancer cells to endothelial cells and hepatocytes. This CD176 scFv provides a basis for future development of recombinant CD176-specific antibodies that can be used in therapeutic application.

生物治疗药物市场的繁荣反映了治疗性抗体药物用于治疗癌症、炎性疾病和难治性感染的可行性和有效性。随着抗体药物临床试验和转化研究中出现的结合效率不高、效应功能降低和不良反应频发等问题的解决,治疗性抗体的修饰在抗体药物的研发进程中得到了前所未有的蓬勃发展。为了提升抗体的结合活性、循环中的半衰期、靶细胞的有效性,并最终实现改善抗体药物的疗效,抗体可主要通过以下途径修饰:①糖基化修饰;②抗体恒定区(Fc)改造;③抗体亚类重构;④构建抗体-药物偶联物(ADC);⑤基于单链可变区片段(scFv)的嵌合抗原受体T细胞(CAR-T);⑥双特异性抗体(bsAb)。过去几十年来全球在修饰型治疗性抗体的领域取得了许多成就,中国作为对于生物治疗药物需求巨大并且拥有巨大研发潜力的国家在该领域亦发挥了积极作用。本文概括了修饰型治疗性抗体在当前国际研究中取得的进展,并在单独的章节中重点介绍了中国在该领域取得的成果。

本工作致力于抗体片段纯化过程的多尺度优化。优化了生产过程中的色谱决策,包括色谱柱的数量及其大小,每批的循环数以及操作流速。使用基于微型实验数据的制造规模模拟数据集,建立了以负载质量、流速和柱床高度为输入的色谱通量数据驱动模型。与其他方法相比,分段线性回归建模方法具有简单、预测精度高的优点。提出了两种混合整数非线性规划(MINLP)模型,结合数据驱动模型,以最小化每克抗体纯化过程的总成本。然后,使用线性化技术和多参数分解将这些MINLP模型重新构造为混合整数线性规划(MILP)模型。研究了两个具有不同色谱柱尺寸替代品的工业相关案例,以证明所提出模型的适用性。

The synthesis of new Schiff base-like ligands with asymmetric substituents pattern and their iron complexes with pyridine as axial ligand is described. Two of the ligands and one of the iron(II) complexes were characterized by single crystal X-ray structure analysis. One of the the iron(II) complexes shows spin crossover behavior while the others remain in the high spin state. The influence of the reduced symmetry of the ligand on the properties of the complexes is discussed.

Allogeneic hematopoietic stem cell transplantation (HSCT) is one of the most effective options for hematological malignancies, and human leukocyte antigen-partially matched related donors (PMRDs) are a valuable option for HSCT. Several protocols (with or without ex vivo T-cell depletion (TCD)) have been established worldwide. TCD including CD34+positive selection and CD3/CD19 depletion has successfully overcome the human leukocyte antigen disparity. However, TCD is associated with prolonged immune deficiencies, increased risks of infectious complications, and high transplantation-related mortality. PMRD HSCT without ex vivo TCD is well developed, and numerous patients have benefitted from it. Here, we review the literature on PMRD HSCT.
