Yin Yang 1 is a critical regulator of B-cell development (2007)

Liu, Huifei, Schmidt-Supprian, Marc, Shi, Yujiang, Hobeika, Elias, Barteneva, Natasha, Jumaa, Hassan, ...

The role of the transcription factor Yin Yang 1 (YY1) in development is largely unknown. Here we show that specific ablation of YY1 in mouse B cells caused a defect in somatic rearrangement in the...

Stochastic pairing of Ig heavy and light chains frequently generates B cell antigen receptors that are subject to editing in vivo (2005)

Novobrantseva, Tatiana, Xu, Shengli, Tan, Joy En-Lin, Maruyama, Mitsuo, Schwers, Stephan, Pelanda, Roberta, ...

We examined the generation and selection of the B cell antibody repertoire through crossing of mice bearing distinct Ig heavy (H) and light (L) chain rearranged variable region transgenes. Ig gene...

Different sensitivity to receptor editing of B cells from mice hemizygous or homozygous for targeted Ig transgenes

Braun, Uschi, Rajewsky, Klaus, Pelanda, Roberta

Ig knock-in mice have been used to study the relative contribution of receptor selection versus clonal selection in the control of autoreactive B cells. The anti-MHC class I 3-83Ig knock-in (3-83Igi)...

κ chain monoallelic demethylation and the establishment of allelic exclusion

Mostoslavsky, Raul, Singh, Nandita, Kirillov, Andrei, Pelanda, Roberta, Cedar, Howard, Chess, Andrew, ...

Allelic exclusion in κ light-chain synthesis is thought to result from a feedback mechanism by which the expression of a functional κ light chain on the surface of the B cell leads to an...

Surface μ Heavy Chain Signals Down-Regulation of the V(D)J-Recombinase Machinery in the Absence of Surrogate Light Chain Components

Galler, Gunther R., Mundt, Cornelia, Parker, Mathew, Pelanda, Roberta, Mårtensson, Inga-Lill, Winkler, Thomas H.

Early B cell development is characterized by stepwise, ordered rearrangement of the immunoglobulin (Ig) heavy (HC) and light (LC) chain genes. Only one of the two alleles of these genes is used to...

Rearrangement and Expression of Immunoglobulin Light Chain Genes Can Precede Heavy Chain Expression during Normal B Cell Development in Mice

Novobrantseva, Tatiana I., Martin, Verena M., Pelanda, Roberta, Müller, Werner, Rajewsky, Klaus, Ehlich, Andreas

In mouse mutants incapable of expressing μ chains, VκJκ joints are detected in the CD43+ B cell progenitors. In agreement with these earlier results, we show by a molecular single cell analysis...

Arhgef1 Is Required by T Cells for the Development of Airway Hyperreactivity and Inflammation

Brown, Jeanette P., Taube, Christian, Miyahara, Nobuaki, Koya, Toshiyuki, Pelanda, Roberta, Gelfand, Erwin W., ...

Rationale: Arhgef1 is an intracellular protein, expressed by hematopoietic cells, that regulates signaling by both G protein–coupled receptors and RhoA, and, consequently, is required for...
