Genetic markers of the antigen-specific T cell receptor locus
نویسندگان
چکیده
The restriction enzyme Eco RI reveals DNA cleavage sites that serve to distinguish the gene locus believed to encode the beta subunit of the major histocompatibility complex (MHC)-restricted, antigen-specific receptor of the T cell in BALB/c mice from that of SJL/J mice. A monoclonal antibody, KJ16-133, also distinguishes BALB/c and SJL/J, because it recognizes an allotypic marker present on a cell-surface heterodimer believed to function as the MHC-restricted, antigen-specific T cell receptor. This study has shown that these two markers cosegregate in a set of BALB/c X SJL/J recombinant inbred (RI) mouse strains, permitting the conclusion that they are linked to within 3 centimorgans of each other, and to the kappa locus on chromosome 6. The tight linkage between these independently derived, totally different T cell markers substantially strengthens the argument that they characterize the MHC-restricted antigen-specific receptor of the effector T cell.

Background: Recently, modification of T cells with chimeric antigen receptor (CAR) has been an attractive approach for adoptive immunotherapy of cancers. Typically, CARs contain a single-chain variable domain fragment (scFv). Most often, scfvs are derived from a monoclonal antibody of murine origin and may be a trigger for host immune system that leads to the T-cell clearance. Nanobody is a spe...

Human leukemic T cells carrying a t(10;14)(q24;q11) chromosome translocation were fused with mouse leukemic T cells, and the hybrids were examined for genetic markers of human chromosomes 10 and 14. Hybrids containing the human 10q+ chromosome had the human genes for terminal deoxynucleotidyltransferase that has been mapped at 10q23-q25 and for C alpha [the constant region of TCRA (the alpha-ch...
