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.

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.

Mucosal B cells are crucial for host defense. The mucosal surfaces exceed 300 m2 in humans and represent indeed the largest part of the body in which immune responses take place daily. Mucosal B cells, located in the gut, respiratory, and urogenital mucosae as well as in skin, salivary, mammary, and lacrimal glands, are very important to protect ...

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 ...

Cellular reprogramming is an interplay between the original starting cell's plasticity and the (epi)genetic mechanisms used to drive this cell towards a new fate. Our capacity to reprogram mature cells into progenitors thus greatly depends on the inherent physiological plasticity of the initial cell.

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.

Discrimination between self and non-self in humoral immunity is mediated in part by elimination or inactivation of self-reactive B-cell clones. This type of repertoire censoring requires that self-reactive B cells make a choice between these and alternative cellular fates.

Extraordinary progress has been made in refining our understanding of the B-cell antigen receptor complex, the role of protein-tyrosine phosphorylation as the key intermediary in immunoglobulin signal transduction, and in identifying candidate effectors of immunoglobulin-mediated signaling.

Publisher Summary B-lymphocytes provide the humoral (antibody-mediated) arm of the adaptive immune system. Like all leukocytes, B cells develop from hematopoietic stem cells in the bone marrow. The bone marrow is a tissue where B cells of all developmental stages can be isolated.
