Genetic engineering of chimeric antigen receptors using lamprey derived variable lymphocyte receptors
Chimeric antigen receptors (CARs) are used to redirect effector cell specificity to selected cell surface antigens. Using CARs, antitumor activity can be initiated in patients with no prior tumor specific immunity. Although CARs have shown promising clinical results, the technology remains limited by the availability of specific cognate cell target antigens. To increase the repertoire of target...
متن کاملCytotoxicity Mediate Complement-Dependent Lamprey Variable Lymphocyte Receptors
An alternative adaptive-immune system is present in the most basal vertebrates—lampreys and hagfish—the only surviving jawless vertebrates. These eel-like fish use leucine-rich repeat–based receptors for Ag recognition instead of the Ig-based receptors used in jawed vertebrates. We report that in Japanese lamprey (Lampetra japonica), variable lymphocyte receptor (VLR)B interacts with C1q and C3...
متن کاملEngineering Chimeric Antigen Receptors
Chimeric antigen receptors (CARs) are recombinant protein molecules that redirect cytotoxic lymphocytes toward malignant and other target cells. The high feasibility of manufacturing CAR-modified lymphocytes for the therapy of cancer has spurred the development and optimization of new CAR T cells directed against a broad range of target antigens. In this review, we describe the main structural ...
متن کاملVariable lymphocyte receptors in hagfish.
A previously uncharacterized type of variable lymphocyte receptors (VLR) was identified recently in the Sea lamprey. This jawless vertebrate generates an extensive VLR repertoire through differential insertion of neighboring diverse leucine-rich repeat (LRR) cassettes into an incomplete germ-line VLR gene. We report here VLR homologs from two additional lamprey species and the presence of two t...
متن کاملLamprey TLRs with properties distinct from those of the variable lymphocyte receptors.
Fish express mammalian-type (M-type) TLRs consisting of leucine-rich repeats (LRRs) and Toll-IL-1R (TIR) homology domain for immunity, whereas invertebrates in deuterostomes appear to have no orthologs of M-type TLRs. Lampetra japonica (lamprey) belongs to the lowest class of vertebrates with little information about its TLRs. We have identified two cDNA sequences of putative TLRs in the lampre...
