model shows that mature B cells specific to one antigen largely possess a single VDJ recombination. The model allows first-principle calculation of the probability, p, that two zebrafish responding to the same antigen will select the same VDJ recombination. This probability p increases with the B cell population size and the B cell selection

VDJ recombination occurs in the BCR-H, TCR-β and -δ chains. The BCR-L (κ and λ), TCR-α and -γ chains lack D segments

Vdj recombination in b cells

V(D)J recombination occasionally happens in natural killer (NK) and dendritic cells [1, 2]. So the answer to my question is that V(D)J recombination is not restricted to B and T cell development. I would like to thank @swbarnes2 for pointing out the importance of RAG1 in V(D)J recombination. http://armandoh.org/Immunology - Antibody Somatic (VDJ) RecombinationAntibody Productionhttps://www.facebook.com/ArmandoHasudunganSupport me: http://www.patr This video gives a birds eye view on VDJ recombination and generation of antibody diversity.

27 Jan 2019 The process of generating the vast diversity of immunoglobulin receptors and secreted antibodies begins with the recombination of the joining (JH), diversity ( DH) and variable (VH) genes in the immunoglobulin heavy chain&n

During cell maturation, the B cell splices out the DNA of all but one of the genes from each region and combine the three remaining genes to form one VDJ segment.
