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...

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
如题,IGHV1-69*01中的1是代表一种胚系基因吗?那后面的69*01又是什么意思呢?
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 ...

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...
Of interest, the most persistent CLL B cell clone in both patients was characterized by the expression of an unmutated IGHV1-69 gene rearrangement [16]. The other coexisting clones expressed different BcR IGs rearrangements, either mutated or unmutated, but none of them persisted during the ...
