摘要： In the bone marrow and spleen, the developing B cell populations undergo both negative and positive selections to shape their B cell receptor repertoire. To gain insight into the shift of the immunoglobulin heavy (IgH) chain repertoire during B cell development, we undertook large scale Ig μ chain repertoire analysis of pre-B, immature B and spleen B cell populations. We found that the majority of V gene segments, V families, J and D gene segments, were observed to have significantly different usage frequencies when three B cell populations were compared, but the usage profile of the V D, and J genes between different B cell populations showed high correlations. In both productive and nonproductive rearrangements, the length of CDRH3 shortened significantly on average when B cells entered the periphery. However, the CDRH3 length distribution of nonproductive rearrangements did not follow a Gaussian distribution, but decreased successively in the order 3 -2, 3 -1 and 3 , suggesting a direct correlation between mRNA stability and CDRH3 length patterns of nonproductive rearrangements. Further analysis of the individual components comprising CDRH3 of productive rearrangements indicated that the decrease in CDRH3 length was largely due to the reduction of N addition at the 5′ and 3′ junctions. Moreover, with development, the amino acid content of CDRH3 progressed toward fewer positively charged and nonpolar residues but more polar residues. All these data indicated that the expressed Ig μ chain repertoire, especially the repertoire of CDRH3, was fine-tuned when B cells passed through several checkpoints of selection during the process of maturation.

摘要： Heavy chain only antibodies (HCAbs) represent a rare type of antibody that is devoid of light chains and the CH1 domain that have been reported in cartilaginous fish and camelids. By analyzing transcript data and genome sequences, we conducted a comprehensive analysis of Bactrian camel immunoglobulin heavy chain genes. Based on the transcript data, one gene, five genes, one gene and one gene were found. Additionally, the variable region of HCAbs (VHH) and the conventional antibodies (VH) sequences associated with the , and genes were amplified. Based on these genome sequences, seven , six , , , , , and genes and a portion of a gene were observed. Different Kozak sequences within different VH families were found in our analysis, and the variability index differed between the VHH3 and VH3 families. Phylogenetic analysis of the constant regions of the camelid immunoglobulin genes indicates that these genes appeared before the evolutionary divergence of Bactrian camels and dromedaries.

DQB1*060101 may contribute to susceptibility to immunoglobulin A nephropathy in southern Han Chinese

null

《医学前沿（英文）》 2016年 第10卷 第4期   页码 507-516 doi: 10.1007/s11684-016-0475-6

摘要：

Immunoglobulin A nephropathy (IgAN) is a common form of chronic glomerulonephritis with unknown pathogenesis. Accumulating evidences have shown the ethnic-specific association between certain human leukocyte antigen (HLA) alleles and IgAN susceptibility. This study was designed to explore the relationship between HLA-DQB1 alleles and disease susceptibility and clinical manifestations of patients with IgAN in southern Han Chinese. A PCR sequence-based typing technique was used to detect HLA-DQB1 alleles in 217 IgAN patients and 229 healthy subjects. Clinical data were collected from each patient at the time of renal biopsy. Twenty HLA-DQB1 alleles were detected in IgAN patients and healthy subjects. High frequency of HLA-DQB1*060101 and low frequency of HLA-DQB1*030101 were observed in IgAN patients compared with healthy controls. Further stratification analysis revealed that the frequency of DQB1*060101 was significantly higher in patients with urine protein≥1.0 g/24 h than in patients with urine protein<1.0 g/24 h. In combination with our previous DRB1 results, we also analyzed the association of DRB1-DQB1 haplotypes with IgAN. We found that the frequency of haplotype DRB1*090102-DQB1*060101 was significantly higher [odds ratio (OR) = 4.409, Pc = 0.016], whereas that of HLA-DRB1*070101-DQB1*020101 was significantly lower (OR= 0.194, Pc = 0.016) compared with healthy controls. Our study indicated that HLA-DQB1*060101 alleles may be a potential predictor of high-risk IgAN susceptibility in Chinese Han population.

《化学科学与工程前沿（英文）》 2019年 第13卷 第1期   页码 70-79 doi: 10.1007/s11705-018-1745-4

摘要： The mixed-mode resins for protein adsorption have been prepared by a novel strategy, copolymer grafting. Specially, the copolymer-grafted resins CG-M-A with two functional groups, 5-amino-benzimidazole (ABI) and methacryloxyethyltrimethyl ammonium chloride (METAC), have been prepared through surface-initiated activator generated by electron transfer for atom transfer radical polymerization of METAC and glycidyl methacrylate (GMA), followed by a ring-open reaction to introduce ABI. The charge and hydrophobicity of CG-M-A resins could be controlled by manipulating the addition of METAC and GMA/ABI. Besides, METAC and ABI provided positive effects together in both protein adsorption and elution: dynamic binding capacity of human Immunoglobulin G (hIgG) onto CG-M-A resin with the highest ligand ratio of METAC to ABI is 46.8 mg·g at pH 9 and the elution recovery of hIgG is 97.0% at pH 5. The separation experiment showed that purity and recovery of monoclonal antibody from cell culture supernatant are 96.0% and 86.5%, respectively, indicating that copolymer-grafted mixed-mode resins could be used for antibody purification.

摘要： In this study, we introduced the bovine immunoglobulin μ heavy-chain gene (the orphaned gene on BTA11) into mouse germline cells. Bovine IgM was highly expressed in selected transgenic lines, and it largely inhibited rearrangements of the endogenous immunoglobulin heavy chain (IgH) genes in these lines. The forced expression of bovine IgM resulted in reduced numbers of pro- and pre-B cells but increased the number of immature B cells in the transgenic mice. Bovine IgM-expressing B cells can migrate from the bone marrow to the spleen, but most of the cells are arrested at the T1 transitional B cell stage, leading to a significantly lower number of T2 transitional and mature B cells in the spleen. Although the serum concentrations of endogenous IgM and IgG in the transgenic mice were significantly decreased, the IgA levels were slightly increased compared to the WT mice. The bovine IgM level in the serum was only one-tenth to one-fifth of that of endogenous mouse IgM, suggesting that most of the serum immunoglobulin were contributed by endogenous IgH gene-expressing B cells. These transgenic mice also exhibited a lower frequency of unique complementarity determining region 3 (CDR3) sequences in their VH repertoire and Vκ repertoire but exhibited an increased frequency of unique CDR3 in their Vλ repertoire. Compared to the WT mice, the transgenic mice had a significantly higher percentage of mouse IgM-expressing B cells that expressed λ chains. Finally, we showed that the transgenic mice were deficient in a specific antibody response to antigen stimulation.

摘要：

The essential role of immunoglobulin G (IgG) in immune system regulation and combatting infectious diseases cannot be fully recognized without an understanding of the changes in its N-glycans attached to the asparagine 297 of the Fc domain that occur under such circumstances. These glycans impact the antibody stability, half-life, secretion, immunogenicity, and effector functions. Therefore, in this study, we analyzed and compared the total IgG glycome—at the level of individual glycan structures and derived glycosylation traits (sialylation, galactosylation, fucosylation, and bisecting N-acetylglucosamine (GlcNAc))—of 64 patients with influenza, 77 patients with coronavirus disease 2019 (COVID-19), and 56 healthy controls. Our study revealed a significant decrease in IgG galactosylation, sialylation, and bisecting GlcNAc (where the latter shows the most significant decrease) in deceased COVID-19 patients, whereas IgG fucosylation was increased. On the other hand, IgG galactosylation remained stable in influenza patients and COVID-19 survivors. IgG glycosylation in influenza patients was more time-dependent: In the first seven days of the disease, sialylation increased and fucosylation and bisecting GlcNAc decreased; in the next 21 days, sialylation decreased and fucosylation increased (while bisecting GlcNAc remained stable). The similarity of IgG glycosylation changes in COVID-19 survivors and influenza patients may be the consequence of an adequate immune response to enveloped viruses, while the observed changes in deceased COVID-19 patients may indicate its deviation.

摘要：

Immunoglobulin G (IgG) is the most abundant plasma glycoprotein and a prominent humoral immune mediator. Glycan composition affects the affinity of IgG to ligands and consequent immune responses. The modification of IgG N-glycosylation is considered to be one of the various mechanisms by which sex hormones modulate the immune system. Although the menstrual cycle is the central sex hormone-related physiological process in most women of reproductive age, IgG N-glycosylation dynamics during the menstrual cycle have not yet been investigated. To fill this gap, we profiled the plasma IgG N-glycans of 70 healthy premenopausal women at 12 time points during their menstrual cycles (every 7 days for 3 months) using hydrophilic interaction ultra-performance liquid chromatography (HILIC-UPLC). We observed cyclic periodic changes in the N-glycosylation of IgG in association with the menstrual cycle phase and sex hormone concentration in plasma. On the integrated cohort level, the modeled average menstrual cycle effect on the abundance of IgG N-glycosylation traits was low for each trait, with the highest being 1.1% for agalactosylated N-glycans. However, intrapersonal changes were relatively high in some cases; for example, the largest difference between theminimum and maximum values during themenstrual cycle was up to 21% for sialylated N-glycans. Across all measurements, the menstrual cycle phase could explain up to 0.72% of the variation in the abundance of a single IgG glycosylation trait of monogalactosylation. In contrast, up to 99% of the variation in the abundance of digalactosylation could be attributed to interpersonal differences in IgG N-glycosylation. In conclusion, the average extent of changes in the IgG N-glycopattern that occur during the menstrual cycle is small; thus, the IgG N-glycoprofiling of women in large sample-size studies can be performed regardless of menstrual cycle phase.

摘要：

食用煮熟的小龙虾可能导致哈夫病（HD），该病被认为是由不明毒素引起的，而病因尚不清楚。N-糖组的剖析将促进破译疾病的分子机制，而HD相关的糖基化从未被探索过。2019—2020年期间，本研究团队招募了来自武汉市疾病预防控制中心的90份HD患者和对照组血清样本。本文中，采用基于高通量的正交质谱对HD中血清和血清衍生的IgG的N-糖组谱进行了表征。数据显示，HD与总血清糖蛋白的核心岩藻糖基化和单半乳糖醇化升高有关。血清IgG水平是HD患者的良好指标。此外，IgG的差异半乳糖基化和唾液酸化与HD密切相关。值得注意的是，IgG1和IgG2的半乳糖基化和唾液酸化的变化具有亚类特异性。有意义的是，IgG2或IgG3/4的唾液酸化和半乳糖基化改变与HD的临床标志物密切相关。本研究表明差异化IgG N-糖基化与HD的关联，为这种罕见疾病的病因提供了新的见解。

摘要：

亚临床动脉粥样硬化和代谢紊乱是心血管健康的重要风险因素，应用免疫球蛋白G（IgG）N-聚糖模式作为炎症指标表征其发病风险已有研究报道。然而，对于IgG N-糖基谱在心血管疾病（CVD）风险分层中的能力仍然未知。本研究旨在利用IgG N-糖基标志物开发追踪心血管疾病风险的年龄指数。本研究基于横断面调查，从Busselton健康和老龄研究中共招募1465名40~70岁之间的个体。使用机器学习递归特征消除和惩罚回归算法逐步筛选特征糖基，并开发IgG N-糖基化心血管年龄（GlyCage）指数，以反映归因于心血管风险的与真实年龄间的偏差。结果显示，对GlyCage指数贡献最大的是具有双分叉N-乙酰葡萄糖胺（GlcNAc）的岩藻糖基化N-聚糖（GP6, FA2B）和具有双分叉GlcNAc的双半乳糖基化N-聚糖（GP13, A2BG2）。GlyCage独立于真实年龄，与较高的Framingham十年心血管风险[优势比（OR）为1.09；95% CI: 1.05~1.13]和患心血管疾病概率（OR, 1.07; 95% CI: 1.01~1.13）显著相关。GlyCage大于真实年龄三年及以上的个体，其心血管风险和心血管疾病患病概率增加，调整后的OR值分别为2.22（95% CI：1.41~3.53）和2.71（95% CI: 1.25~6.41）。GlyCage指数区分十年心血管风险和事件的ROC曲线下面积（AUC）值分别为0.73和0.65，而真实年龄为0.65和0.63。因此，本研究开发的GlyCage指数利用IgG N-糖基谱追踪心血管健康水平。GlyCage和真实年龄之间的差距能够独立地表征心血管风险，提示IgG N-糖基化在心血管疾病的发病机制中起作用。GlyCage指数对心血管风险的预测能力需要在其他人群中进行外部和纵向验证。
