Molecular genetic analysis of 178 I-Abm12-reactive T cells.

Molecular genetic analysis of 178 I-Abm12-reactive T cells

We have studied the genetic diversity of the TCR repertoire to the murine alloantigen I-Abm12 by generating a panel of 178 C57BL/10-derived I-Abm12-reactive T cell hybridomas. The expression of V alpha and V beta gene families was examined in this panel and the frequency of expression of V beta, but not ofV alpha, gene families differed significantly from that observed in a companion panel of r...

Molecular Analysis of Lipid-Reactive Vδ1 γδ T Cells Identified by CD1c Tetramers.

CD1c is abundantly expressed on human dendritic cells (DC) and B cells, where it binds and displays lipid Ags to T cells. In this study, we report that CD1c tetramers carrying Mycobacterium tuberculosis phosphomycoketide bind γδ TCRs. An unbiased method of ligand-based TCR selection detects interactions only with Vδ1(+) TCRs, and mutational analyses demonstrate a role of the Vδ1 domain during r...

Molecular Analysis of Lipid-Reactive Vd1 gd T Cells Identified by CD1c Tetramers

Molecular genetic analysis of single cells.

Preimplantation genetic diagnosis (PGD) has experienced a considerable technical evolution since its first application in the early 1990s. The technology for single-cell genetic analysis has reached an extremely high level of accuracy and enabled the possibility of performing multiple diagnoses from one cell. Diagnosis of a monogenic disease can now be combined with aneuploidy screening, human ...

Human T Lymphotropic Virus Type I (HTLV-I) Oncogenesis: Molecular Aspects of Virus and Host Interactions in Pathogenesis of Adult T cell Leukemia/Lymphoma (ATL)

    The study of tumor viruses paves the way for understanding the mechanisms of virus pathogenesis, including those involved in establishing infection and dissemination in the host tumor affecting immune-compromised patients. The processes ranging from viral infection to progressing malignancy are slow and usually insufficient for establishment of transformed cells that develop cancer in only ...
