Abstract:
Roughly 30% of patients with chronic lymphocytic leukemia (CLL) carry immunoglobulin receptors with highly similar primary sequences. Highly similar, quasi-identical immunoglobulins are termed stereotyped. Patients with CLL can be assigned to different subsets expressing different types of stereotyped immunoglobulin receptors. Reliable identification of stereotypy may assist in the molecular classification of CLL and thus better-guided, compartmentalized research. In several major subsets, stereotypy extends from shared primary sequences to shared clinicobiological features and outcome. Reliable identification of stereotypy in CLL may pave the way for tailored treatment strategies applicable to each major stereotyped subset.

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...
Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
