V (D)J recombination (variable–diversity–joining rearrangement) 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.

Immunoglobulins and T cell receptors are composed of two polypeptide chains, each of which contributes to the antigen binding domain. The exons encoding the antigen binding domains are assembled from so-called V (variable), D (diversity), and J (joining) gene segments by “cut and paste” DNA rearrangements.

Apr 19, 2002 · We review our current understanding of the V (D)J recombination reaction and how it is regulated during lymphocyte development. We also discuss how defects in the mechanism or regulation of V (D)J recombination can lead to human disease.

VDJ rearrangement is a process by which the genes responsible for encoding the variable region of the B-cell receptor and T-cell receptor are rearranged to create a diverse repertoire of receptors capable of recognizing a wide variety of antigens.

Jul 11, 2018 · VDJ are Variable, Diversity and joining segments of DNA that transcribe into various polypeptides by producing different combinations. In this article, I will explain to you the structure of the antibody, the mechanism of VDJ recombination and the …

Jun 19, 2016 · VDJ rearrangement on ‘H’ chain occurs in Pro-B cells to produce Heavy chain. VJ rearrangement on ‘L’ chain occurs in Precursor B cells to produce Light chain. After the re-arrangement, the B cells are now called Immature B cells .

VDJ recombination refers to a site-specific recombination reaction in vertebrate lymphocytes that combines V (variable), J (joining), and D (diversity) gene segments to generate a diverse range of immunoglobulins and T-cell receptors essential for the vertebrate immune system.

May 3, 2021 · VDJ recombination is the mechanism by which B cells generate antibody diversity. It involves genetic recombination of variable (V), diversity (D), and joining (J) gene segments in B cell progenitors. This creates a unique B cell receptor on each mature B cell.

V (D)J recombination is an essential mechanism of the adaptive immune system, producing a diverse set of antigen receptors in developing lymphocytes via regulated double strand DNA break and subsequent repair.

V (D)J recombination is a mechanism of genetic recombination that occurs in vertebrates, which randomly selects and assembles segments of genes encoding specific proteins with important roles in the immune system. [1] .
