Basal Immunoglobulin Signaling Actively Maintains Developmental Stage in Immature B Cells (2005)

Lina E. Tze, Brian R. Schram, Kong-Peng Lam, Kristin A. Hogquist, Keli L. Hippen, Jiabin Liu, ...

Gene rearrangement is a hallmark of B cell maturation. By interrupting basal cell signaling through the rearranged IgM receptor, immature B cells "back-differentiate" to an earlier stage in their...

Basal Immunoglobulin Signaling Actively Maintains Developmental Stage in Immature B Cells (2005)

Lina E. Tze, Brian R. Schram, Kong-Peng Lam, Kristin A. Hogquist, Keli L. Hippen, Jiabin Liu, ...

In developing B lymphocytes, a successful V(D)J heavy chain (HC) immunoglobulin (Ig) rearrangement establishes HC allelic exclusion and signals pro-B cells to advance in development to the pre-B...

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...

B cell development and activation defects resulting in xid-like immunodeficiency in BLNK/SLP-65-deficient mice (2000)

Xu, Shengli, Tan, Joy En-Lin, Wong, Esther Poh-Ying, Manickam, Arunkumar, Ponniah, Sathivel, Lam, Kong-Peng

Engagement of the B cell receptor (BCR) leads to the activation of tyrosine kinases and other signaling molecules that ultimately determine the type and magnitude of the B lymphocyte's cellular...

A high frequency of hybridomas from M54 {micro} heavy chain transgenic mice initially co-express transgenic and rearranged endogenous {micro} genes (1993)

Lam, Kong-Peng, Herzenberg, L. A., Stall, A. M., Okumura, K.

The M54 transgenic mouse line, which carries the 17.2.25 Ig μ heavy chain gene, rearranges Ig eavy chains and expresses both transgenic and endogenous μ. B cell lineage development is selectively...

Rapid elimination of mature autoreactive B cells demonstrated by Cre-induced change in B cell antigen receptor specificity in vivo

Lam, Kong-Peng, Rajewsky, Klaus

Developing autoreactive B cells edit their B cell antigen receptor (BCR) in the bone marrow and are clonally deleted when they fail to reexpress an innocent BCR. Here, inducible Cre-loxP-mediated...

B-Cell Maturation Protein, Which Binds the Tumor Necrosis Factor Family Members BAFF and APRIL, Is Dispensable for Humoral Immune Responses

Xu, Shengli, Lam, Kong-Peng

B-cell maturation protein (BCMA) is a member of the tumor necrosis factor (TNF) receptor family and is expressed in B lymphocytes. BCMA binds two TNF family members, BAFF and APRIL, that stimulate...

Cbp Deficiency Alters Csk Localization in Lipid Rafts but Does Not Affect T-Cell Development

Xu, Shengli, Huo, Jianxin, Tan, Joy En-Lin, Lam, Kong-Peng

The ubiquitously expressed transmembrane adaptor Csk-binding protein (Cbp) recruits Csk to lipid rafts, where the latter exerts its negative regulatory effect on the Src family of protein tyrosine...

TACI and BAFF-R mediate isotype switching in B cells

Castigli, Emanuela, Wilson, Stephen A., Scott, Sumi, Dedeoglu, Fatma, Xu, Shengli, Lam, Kong-Peng, ...

The tumor necrosis factor family members BAFF and APRIL induce Ig isotype switching in human B cells. We analyzed the ability of BAFF and APRIL to induce isotype switching in murine B cells to IgG1,...

Delayed Cellular Maturation and Decreased Immunoglobulin κ Light Chain Production In Immature B Lymphocytes Lacking B Cell Linker Protein

Xu, Shengli, Lam, Kong-Peng

B cell linker (BLNK) protein is a component of the B cell receptor (BCR) signaling pathway and BLNK−/− mice have a block in B lymphopoiesis at the pro-B/pre-B cell stage. To study the effect of...

B Cell Antigen Receptor Specificity and Surface Density Together Determine B-1 versus B-2 Cell Development

Lam, Kong-Peng, Rajewsky, Klaus

Mice expressing the immunoglobulin (Ig) heavy (H) chain variable (V) region from a rearranged VH12 gene inserted into the IgH locus generate predominantly B-1 cells, whereas expression of two other...
