OcaB Is Required for Normal Transcription and V(D)J Recombination of a Subset of Immunoglobulin κ Genes

OcaB, a transcriptional coactivator also known as Bob-1 or OBF-1, was isolated on the basis of its ability to enhance transcription of immunoglobulin (Ig) genes in vitro. Paradoxically, OcaB(-/-) mice showed no apparent deficiency in Ig gene transcription, only cellular immune defects including absence of germinal centers (GC) and decreased numbers of immature B cells; the genes targeted by Oca...

The Serine/Threonine Phosphatase PP4 Is Required for Pro-B Cell Development through Its Promotion of Immunoglobulin VDJ Recombination

PP4 phosphatase regulates a number of crucial processes but the role of PP4 in B cells has never been reported. We generated B cell-specific pp4 knockout mice and have identified an essential role for PP4 in B cell development. Deficiency of PP4 in B lineage cells leads to a strong reduction in pre-B cell numbers, an absence in immature B cells, and a complete loss of mature B cells. In PP4-def...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Deacetylase activity of histone deacetylase 3 is required for productive VDJ recombination and B-cell development.

Histone deacetylase 3 (HDAC3) is the catalytic component of NCoR/SMRT corepressor complexes that mediate the actions of transcription factors implicated in the regulation of B-cell development and function. We crossed Hdac3 conditional knockout mice with Mb1-Cre knockin animals to delete Hdac3 in early progenitor B cells. The spleens of Hdac3F/-Mb1-Cre+/- mice were virtually devoid of mature B ...

VDJ Recombination

Artemis is the newest player in VDJ recombination and double strand break repair. First identified in radiation-sensitive and immune-deficient patients, it was recently shown to interact with DNA-dependent protein kinase catalytic subunit (DNA-PKcs) and have nuclease activity, becoming the most popular candidate for the opening of hairpin coding ends. Reports presented in this issue (1) and in ...
