High-affinity lamprey VLRA and VLRB monoclonal antibodies.
Lamprey are members of the ancestral vertebrate taxon (jawless fish), which evolved rearranging antigen receptors convergently with the jawed vertebrates. But instead of Ig superfamily domains, lamprey variable lymphocyte receptors (VLRs) consist of highly diverse leucine-rich repeats. Although VLRs represent the only known adaptive immune system not based on Ig, little is known about their ant...
متن کاملStructure and specificity of lamprey monoclonal antibodies.
Adaptive immunity in jawless vertebrates (lamprey and hagfish) is mediated by lymphocytes that undergo combinatorial assembly of leucine-rich repeat (LRR) gene segments to create a diverse repertoire of variable lymphocyte receptor (VLR) genes. Immunization with particulate antigens induces VLR-B-bearing lymphocytes to secrete antigen-specific VLR-B antibodies. Here, we describe the production ...
متن کاملA structural basis for antigen recognition by the T cell-like lymphocytes of sea lamprey.
Adaptive immunity in jawless vertebrates is mediated by leucine-rich repeat proteins called "variable lymphocyte receptors" (VLRs). Two types of VLR (A and B) are expressed by mutually exclusive lymphocyte populations in lamprey. VLRB lymphocytes resemble the B cells of jawed vertebrates; VLRA lymphocytes are similar to T cells. We determined the structure of a high-affinity VLRA isolated from ...
متن کاملMonoclonal Antibodies
SUMMARY Monoclonal Antibodies are identical antibodies and Can be generated in ultimated amounts by countinuos cultures of single antibody- secreting cells. These cell lines are produced by cell fusion of normal lymphocytes to cells of a myeloma tumor cell line, which confers on the antibody producing hybrid cell, immortality and the ability grow as atumor in animals. monoclonal antibodies c...
متن کاملRegulation of antigen-receptor gene assembly in hagfish.
Variable lymphocyte receptors (VLRs) are antigen receptors in the jawless vertebrates lamprey and hagfish. VLR genes are classified into VLRA and VLRB, and lymphocytes expressing VLRA are T-cell-like, whereas those expressing VLRB are B-cell-like in the sea lamprey. Diverse VLR genes are assembled somatically in lymphocytes; however, how the assembly is regulated is still largely unknown. Here,...
