A Diverse Repertoire of Human Immunoglobulin Variable Genes in a Chicken B Cell Line is Generated by Both Gene Conversion and Somatic Hypermutation.

Frontiers in immunology

Leighton PA, Schusser B, Yi H, Glanville J, Harriman W.
PMID: 25852694
Front Immunol. 2015 Mar 20;6:126. doi: 10.3389/fimmu.2015.00126. eCollection 2015.

Chicken immune responses to human proteins are often more robust than rodent responses because of the phylogenetic relationship between the different species. For discovery of a diverse panel of unique therapeutic antibody candidates, chickens therefore represent an attractive host...

Anti-ganglioside anti-idiotypic vaccination: more than molecular mimicry.

Frontiers in oncology

Vázquez AM, Rodrèguez-Zhurbenko N, López AM.

Front Oncol. 2012 Nov 20;2:170. doi: 10.3389/fonc.2012.00170. eCollection 2012.

Surgery, chemotherapy, and radiation therapy are standard modalities for cancer treatment, but the effectiveness of these treatments has reached a plateau. Thus, other strategies are being explored to combine with the current treatment paradigms in order to reach better...

Cloning and Expression of Single-Chain Fragments (scFv) from Mouse and Rat Hybridomas.

For cloning and expressing the antigen-binding variable (Fv) portion of an antibody in Escherzchia coli, vectors have been constructed that combine the two variable regions (V(H) and V(L)) with a peptide linker (1-3). The genetic information for V(H) and...

iScience. 2020 Mar 27;23(3):100941. doi: 10.1016/j.isci.2020.100941. Epub 2020 Feb 27.

Repair of DNA double-stranded breaks (DSBs) during lymphocyte development is essential for V(D)J recombination and forms the basis of immunoglobulin variable region diversity. Understanding of this process in lymphogenesis has historically been centered on the study of RAG1/2 recombinases...

The role of HIRA-dependent H3.3 deposition and its modifications in the somatic hypermutation of immunoglobulin variable regions.

Proceedings of the National Academy of Sciences of the United States of America

Yu G, Zhang Y, Gupta V, Zhang J, MacCarthy T, Duan Z, Scharff MD.
PMID: 34873043
Proc Natl Acad Sci U S A. 2021 Dec 14;118(50). doi: 10.1073/pnas.2114743118.

The H3.3 histone variant and its chaperone HIRA are involved in active transcription, but their detailed roles in regulating somatic hypermutation (SHM) of immunoglobulin variable regions in human B cells are not yet fully understood. In this study, we...

Origin and Function of Circulating Plasmablasts during Acute Viral Infections.

Frontiers in immunology

Fink K.
PMID: 22566959
Front Immunol. 2012 Apr 17;3:78. doi: 10.3389/fimmu.2012.00078. eCollection 2012.

Activated B cells proliferate and differentiate into antibody-producing cells, long-lived plasma cells, and memory B cells after immunization or infection. Repeated encounter of the same antigen triggers the rapid re-activation of pre-existing specific memory B cells, which then potentially...

Functional Versatility of AGY Serine Codons in Immunoglobulin Variable Region Genes.

Frontiers in immunology

Detanico T, Phillips M, Wysocki LJ.
PMID: 27920779
Front Immunol. 2016 Nov 22;7:525. doi: 10.3389/fimmu.2016.00525. eCollection 2016.

In systemic autoimmunity, autoantibodies directed against nuclear antigens (Ags) often arise by somatic hypermutation (SHM) that converts AGT and AGC (AGY) Ser codons into Arg codons. This can occur by three different single-base changes. Curiously, AGY Ser codons are...

Transl Oncol. 2020 Mar;13(3):100744. doi: 10.1016/j.tranon.2020.100744. Epub 2020 Feb 29.

Mantle cell lymphoma (MCL) is an aggressive and rare B-cell non-Hodgkin lymphoma classified in two clinicopathological subtypes according to SOX11 expression and mutation state of immunoglobulin variable region heavy chain (IgVH) gene. The transcription factor SOX11, overexpressed in 78%-93%...

T-cell receptor binding to MHC-bound peptides plays a key role in discrimination between self and non-self. Only a subset, typically a pentamer, of amino acids in a MHC-bound peptide form the motif exposed to the T-cell receptor. We categorize...
