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. During the large pre-B cell stage, the cell presents a pre-B-cell receptor on it’s surface, which is comprised of the heavy chain of the finished B-cell.

This stems from defects in the V(D)J recombination processes common to T and B cell maturation, but is not required for NK cell development. Unlike the RAG mutant preB cells, scid pre-B cells undergo the initial steps of VDJ recombination relatively efficiently, including RS sequence recognition and introduction of precise doublestrand breaks. Scid pre-B cells also form RS joins with relatively normal fidelity and efficiency. Se hela listan på bionity.com Question: An Antigen Activates VDJ Recombination In B Cells. True Or False.

It results in the highly diverse repertoire of antibodies/immunoglobulins and T c 11 Feb 2015 We quantify the VDJ recombination and somatic hypermutation processes in human B-cells us- ing probabilistic inference methods on high-throughput DNA sequence repertoires of human B-cell receptor heavy chains. The process of allelic exclusion ensures that once a functional VDJH rearrangement has been achieved, the other IGH allele is generally excluded from further recombination Both the light- and heavy-chain genes are encoded by gene segments that are genetically rearranged during a process known as V(D)J recombination.
