Abstract:
Repertoire sequencing of B cells is the high-throughput profiling of B cell receptors (BCR) expressed on the surface of B cells and of immunoglobulins (Ig) expressed by antibody secreting cells. Each BCR/Ig transcript has a unique complementarity-determining region 3 (CDR3) sequence that can be used to identify and track individual B cell lymphocytes over time and throughout different compartments of the human body. B cell differentiation can be further tracked by assessing the point mutations acquired during affinity maturation via somatic hypermutation (SHM). Here we describe a method for high-throughput sequencing of the variable region of Ig heavy-chain transcripts for repertoire analysis of human B cells on the Illumina Miseq platform.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
