Objective:
To review the current and the potential research and clinical use of VLRBs.
Methods:
A literature search was conducted for English studies published in the past 20 years using the terms "Variable Lymphocyte Receptor," "VLR," "VLRB" or "Repebody." Only primary reports were included.
Results:
VLRB-based technologies are currently being investigated for diagnosis, imaging, and treatment of diverse conditions including solid organ and hematological malignancies, infectious diseases, autoimmunity, and degenerative and metabolic disorders. VLRB mAbs can be used to directly recognize disease biomarkers, such as B cells from chronic lymphocytic leukemia, or to deliver drugs to the brain or cancer cells. The VLRB C-terminal multimerization domain has been utilized to create vaccines while VLR-based chimeric antigen receptor (CAR) T cell constructs are being investigated for cancer therapies.
Conclusions:
The extensive knowledge gained with VLRB mAbs in diverse in vitro and in vivo models emphasizes their promise for translation into clinical applications and readiness for prime time.

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,...
