The first is called V(D)J (variable, diverse, and joining regions) recombination. 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. 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. VDJ recombination for the heavy chain happens first and happens between the early pro-B to large pre-B stages. VDJ recombination for the light chain happens during the small pre-B cell stage.

Komplement V.47: F07 - mikrob-värdinteraktioner Flashcards | Quizlet fotografera. V (D)J recombination is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively. V J558L DJ H 1 joints were found in the wild-type B cells but were virtually undetectable in μ i/+ κ i/+ B cells (Fig. 2B). The near absence of these joints in the μ i/+ κ i/+ B cells was expected because endogenous VDJ H rearrangements are inhibited by the V B1-8 DJ H replacement ( 16 ).

Somatic hypermutation is a well-documented mechanism for achieving diversification of immune responses in mature B cells. Antibody genes were also found to be modified in such cells in germinal centers by recombination of the V (D)J recombination is a site-specific recombination process that occurs early in the development of B and T lymphocytes. As mentioned earlier, it is required for assembling complete antigen receptor genes from separately encoded germ-line variable (V), diversity (D), and joining (J) segments.
