VDJ recombination the process by which T cells and B cells randomly assemble different gene segments - known as variable (V), diversity (D) and joining (J) genes - in order to generate unique receptors (known as antigen receptors) that can collectively recognize many different types of molecule

The theoretical basis of clonal selection is the assumption that lymphocytes bearing an antigen receptor for an antigen exist long before antigen presentation occurs, explained by the idea of random mutations (VDJ recombination) that occur during lymphocyte maturation.

Whatever their precise role, the coordinated expression in pre-B is essential for the rearrangement of Ig genes, but RAG activity is switched off in mature lymphocytes. The substrates for VDJ recombination are DNA segments, termed coding elements, flanked by short sequences called recombination signal sequences (RSSs) ().The lymphoid-specific proteins RAG1 and RAG2 collaborate to make a double-strand break (DSB) between each RSS and its corresponding coding segment, producing two coding ends and two signal ends. The mouse mutation scid adversely affects the process of VDJ recombination. Attempts to form coding joints, that is, to joint V or D to J gene segments generally fail in developing scid lymphocytes.

These genes are then joined together via a process that deletes some randomly distributed number of nucleotides on their boundaries then joins them together with random “non-templated” nucleotides in the N-region (blue). Somatic recombination occurs physiologically in the assembly of the B cell receptor and T-cell receptor genes (V(D)J recombination), as well as in the class switching of immunoglobulins. Somatic recombination is also important in the process of carcinogenesis . VDJ recombination: a transposase goes to work.

Since, an antibody made to bind one antigen cannot bind to the Answer – Generation of B cell Receptor Diversity.

73. Barreto V, Marques R, Demengeot J. 2001. Early death and severe lymphopenia caused by VDJ recombination proceeds via precise DNA cleavage initiated by the RAG proteins (RAG-1 and RAG-2) at short conserved signal sequences [128]. Whatever their precise role, the coordinated expression in pre-B is essential for the rearrangement of Ig genes, but RAG activity is switched off in mature lymphocytes.

The first step in assembling immunoglobulin and T-cell receptors by V(D)J recombination has similarities to transposon excision. The excised transposon-like element then integrates into DNA targets at random in vitro, but whether this activity significantly threatens the genomic integrity of its host has been unclear.

: 12/23 rule : B cells : class-switch recombination : CSR : double strand breaks : E2A encoded proteins : hairpin : The recombinational process, including randomly choosing a pair of V, D, J segments, introducing double‐strand breaks adjacent to each segment, deleting (or inverting in some cases) the intervening DNA and ligating the segments together, is defined as V (D)J recombination, which contributes to surprising immunoglobulin diversity in vertebrate immune systems.

A 9-month-old baby has been diagnosed with Omenn Syndrome following the development of a rash that spreads to their entire body. The role of T cell receptor α enhancer (E α) cis-acting elements in the developmental regulation of VDJ recombination at the TCR α/δ locus was examined in transgenic mice containing variants of a minilocus VDJ recombination substrate.We demonstrate that the 116-bp Tα1,2 core enhancer fragment of the 1.4-kb E α is sufficient to activate the enhancer-dependent step of minilocus All higher vertebrates (including agriculturally important animals) protect themselves from infection by developing a strong, adaptive immune response. This is possible because lymphocytes are capable of making specific receptors that can recognize virtually any pathogen encoutered.

It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively.
