Zou I forgot everything from immunology except 'degranulation' and 'vdj recombination' that the blue lymphocyte is a T cell and the yellow one is the B cell.

… B cell receptor expressed on cell membrane • After successful VDJ recombination on first chromosome assembled pre-B cell receptor signals to stop recombination of 2 nd chromosome (allelic Late pro-B cell – IGH undergoes V–DJ rearrangement (VDJ rearrangement) with loss of DNA between the joined V and D segments. Recombination can be somewhat imprecise, since during this process several nucleotides may be removed from or added to a junction, so combination of VDJ segments of H chains results in a large number of possible sequences (that is, antibodies). They appear to borrow information from gene segments that are leftovers from the process of assembling antibody DNA in B cells. In a mix and match process called VDJ recombination, B cells use one of many V, D, and J segments to form their antibody genes. What Dale and Jacob were looking at occurs after the VDJ step, when B cells get stimulated The lymphocyte-specific enzymes ___ and ___ make up the ___ complex, a functional endonuclease, which initiates V(D)J recombination in B cells.

This figure shows the chronological order of B cells in different stages of development in the bone marrow. B cells progress from stem cells to pro‐B cells, pre‐B cells and immature pre‐B‐cell stages. Antibodies obtain their diversity through 2 processes.

In support of this possibility, we show that one of the E3 ubiquitin ligase components, called VprBP, is required for B cell development past the pro-B cell stage in mice.

Current evidence suggests that V-D-J recombination is controlled at two levels: regulation of Immunoglobulin (Ig) gene recombination in B-cell development. 13 Oct 2003 In order for the immune system to generate its vast numbers of receptors, B- and T-cell receptor genes are created by recombining preexisting  4 Jul 2019 V(D)J recombination generates antigen receptor diversity by mixing T cells and 50% of transitional and naïve B cells testing positive (15, 16).

VDJ recombination, also known as antigen receptor gene rearrangement or antigen-independent diversification, is a diversity generating assembly process affecting the variable domain of immunoglobulin and TCR genes. : 12/23 rule : B cells : class-switch recombination : CSR : double strand breaks : E2A encoded proteins : hairpin : HMG-1, HMG-2 :

In certain types of SCID, a defect in the development of T and B cells, but normal NK cell function is evident. 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.

V-J rearrangements occur at the recombination signals (RS), which include a heptameric sequence (7 nucleotides) and a nonameric sequence (9 nucleotides) , 

I fully understand that B cells have IgD as the BCR so it takes place there. But what’s the need of that in a T cell which doesn’t have Ig as a receptor nor produces any Ig!! These findings lead us to speculate that the cleavage and joining phases of V(D)J recombination are connected and regulated by a ubiquitin modification pathway. In support of this possibility, we show that one of the E3 ubiquitin ligase components, called VprBP, is required for B cell development past the pro-B cell stage in mice.
