Regulation of B-cell commitment to plasma cells or to memory B cells
Seminars in Immunology, 1997During humoral immune responses, B-lymphocyte activation is followed by differentiation along either the plasma cell pathway or the memory B-cell pathway. Recent studies suggest that CD40-CD40 ligand, OX-OX40 ligand, a group of cytokines and intracellular transcriptional factors may all contribute to B-lymphocyte differentiation control.

CD5 B Cells, a Fetal B Cell Lineage
1993Publisher Summary This chapter presents a short background of CD5 expression on B cells and focuses on the issue of the relationship of CD5 B cells to B cell development, proposing a model that views this subset as the progeny of a fetal B cell differentiation pathway.

In the last two decades, many efforts have been made to better understand the biology of B-lymphoproliferative disorders through the knowledge of physiology and function of the postulated normal counterpart. The follicular mantle B-cells express a typical CD23+ IgM+ IgD+ phenotype and surround the germinal center area in secondary lymphoid organs. CD5+

B-cell receptor regulation of peripheral B cells
Current Opinion in Immunology, 1998Recent studies indicate that immature B cells compete with recirculating B cells for survival signals. The signals, delivered through the B-cell receptor for antigen, induce immature cells to differentiate into recirculating cells and maintain the survival of recirculating cells. They do not induce proliferation or differentiation to antibody-producing

Recent studies have identified CD40 ligand (CD40L) as the critical membrane-expressed molecule responsible for T cell dependent B-cell activation. CD40L co-operates with various cytokines to induce B-cell activation, proliferation, and immunoglobulin isotype switching.

B cell development and activation are accompanied by dynamic genetic alterations including V(D)J rearrangements and immunoglobulin-gene somatic hypermutation and class-switch recombination. Abnormalities in these genetic events can cause chromosomal translocations and genomic mutations, leading to altered expression and function of genes involved in B ...

AbstractPriming of naive lymphocytes is important for yielding efficient immune responses. Mechanisms controlling this process are also important for preventing immune cells from attacking self‐antigens. It is well known that signals provided by innate immune receptors, such as Toll‐like receptors (TLR), are essential to induce dendritic cell ...

In recent years, our understanding of B-cell biology and the roles of B cells in normal immune responses and autoimmunity has increased dramatically. We no longer think of B cells simply as antibody factories. It is clear that these diverse and exquisitely regulated cells may contribute in a multitude of ways to immune responses.

The subunit structure of the B-cell antigen receptor (BCR) and its associated compartmentalization of function confer enormous flexibility for generating signals and directing these toward specific and divergent cell fate decisions. Like all the multichain immune recognition receptors discussed in this volume, assembly of these multi-unit complexes ...

B cells act as immune effectors, primarily through antigen-specific clonal expansion and plasma-cell differentiation. B1 (CD5(+)) B cells and marginal zone B cells dominate T-cell independent humoral responses under the molecular control of activated dendritic cells.
