因此,IGHV1-69抗体不需要发生体细胞突变就能够天然与L452相互作用。通过亲和力实验和真病毒中和实验证明在452位点由疏水氨基酸L突变成亲水氨基酸R几乎能够逃逸所有IGHV1-69的抗体结合与中和。 研究人员进一步分析发现IGHV1-69抗体在Omicron...
2016. IGHV1-69 polymorphism modulates anti-influen- za antibody repertoires, correlates with IGHV utilization shifts and varies by ethnicity. Sci Rep 6: 20842.Avnir Y, Watson CT, Glanville J, Peterson EC, Tallarico AS, Bennett AS, Qin K, Fu Y, Huang CY, Beigel JH, Breden F, Zhu Q,...

近日,中国科学院广州生物医药与健康研究院(广州健康院)与广州医科大学附属第一医院、广州实验室等单位合作在EmergingMicrobes&Infections发表题为Shared IGHV1-69-encoded neutralizing antibodies contribute to the emergence of L452R substitution in SARS-CoV-2 variants的研究论文。
IGHV polymorphism provides a rich source of humoral immune system diversity. One important example is the IGHV1-69 germline gene where the biased use of alleles that encode the critical CDR-H2 Phe54 (F-alleles) to make broadly neutralizing antibodies (HV
目前我只知道IGHV是抗体重链胚系基因，不知道人的抗体重链有几种胚系基因?然后后面的1-69*01就完全不...
B-cell chronic lymphocytic leukemia (B-CLL) patients expressing unmutated immunoglobulin heavy variable regions (IGHVs) use the IGHV1-69 B cell receptor (BCR) in 25% of cases. Since HIV-1 envelope gp41 antibodies also frequently use IGHV1-69 gene segments, we hypothesized that IGHV1-69 ...

Interestingly, the IGHV1-69 Pent+ population observed in patients' samples was generally larger than in donors, supporting the existence of spontaneous memory T-cell responses against IGHV1-69, at least for some HLA-restrictions. Surprisingly, in patients' samples, IGHV1-69-recognizing T cells...
