2Immunogenetic factors driving formation of ultralong VH CDR3 in Bos taurus antibodies显示文摘The antibody repertoire of Bos taurus is characterized by a subset of variable heavy(VH)chain regions with ultralong third complementarity determining regions(CDR3)which,compared to other species,can provide a potent response to challenging antigens like HIV env.These unusual CDR3 can range to over seventy highly diverse amino acids in length and form uniqueβ-ribbon‘stalk’and disulfide bonded‘knob’structures,far from the typical antigen binding site.The genetic components and processes for forming these unusual cattle antibody VH CDR3 are not well understood.Here we analyze sequences of Bos taurus antibody VH domains and find that the subset with ultralong CDR3 exclusively uses a single variable gene,IGHV1-7(VHBUL)rearranged to the longest diversity gene,IGHD8-2.An eight nucleotide duplication at the 3′end of IGHV1-7 encodes a longer V-region producing an extended Fβ-strand that contributes to the stalk in a rearranged CDR3.A low amino acid variability was observed in CDR1 and CDR2,suggesting that antigen binding for this subset most likely only depends on the CDR3.Importantly a novel,potentially AID mediated,deletional diversification mechanism of the B.taurus VH ultralong CDR3 knob was discovered,in which interior codons of the IGHD8-2 region are removed while maintaining integral structural components of the knob and descending strand of the stalk in place.These deletions serve to further diversify cysteine positions,and thus disulfide bonded loops.Hence,both germline and somatic genetic factors and processes appear to be involved in diversification of this structurally unusual cattle VH ultralong CDR3 repertoire.Thaddeus C Deiss Melissa Vadnais Feng Wang Patricia L Chen Ali Torkamani Waithaka Mwangi Marie-Paule Lefranc Michael F Criscitiello Vaughn V Smider 2019Cellular & Molecular Immunology2019,16,1:4
3利用抗高血压药相关的遗传变异发现其潜在的功效和副作用显示文摘通过研究药物靶蛋白基因的自然变异可以了解药物的功效。本研究旨在利用这种方法探索抗高血压药的潜在副作用和再利用潜力。研究者首先确定了血管紧张素转换酶抑制剂(angiotensin converting enzyme inhibitor,ACEI)、β受体阻滞剂和钙拮抗剂的合适代表基因。刘青(译) 叶鹏(校) Gill D Georgakis MK Koskeridis F Jiang L Feng Q Wei WQ Theodoratou E Elliott P Denny JC Malik R Evangelou E Dehghan A Dichgans M Tzoulaki I 2019中华高血压杂志2019,0,9:3

5全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A 2016饲料博览2016,0,12:2
