T-Cell Lymphoma Clonality by Copy Number Variation Analysis of T-Cell Receptor Genes

2021

Simple Summary T-cells defend the human body from pathogenic invasion via specific recognition by T-cell receptors (TCRs). The TCR genes undergo recombination (rearrangement) in a myriad of possible ways to generate different TCRs that can recognize a wide diversity of foreign antigens. However, in patients with T-cell lymphoma (TCL), a particular T-cell becomes malignant and proliferates, resulting in a population of genetically identical cells with same TCR rearrangement pattern. To help diagnose patients with TCL, a polymerase chain reaction (PCR)-based assay is currently used to determine if neoplastic cells in patient samples are of T-cell origin and bear identical (monoclonal) TCR rea…

Isolation of naturally processed peptides recognized by cytolytic T lymphocytes (CTL) on human melanoma cells in association with HLA-A2.1.

1994

Cytolytic T lymphocyte (CTL) clones have previously been derived from peripheral blood of melanoma patient SK29(AV). They lyse autologous melanoma cells but not autologous Epstein-Barr virus (EBV)-transformed B lymphocytes. Immunoselection experiments indicate that these CTL clones recognize 4 different antigens (Aa, Ab, B, C) in association with a single HLA restriction element, HLA-A2.1. While the expression of antigens B and C appears to be confined to SK29-melanoma cells, antigens Aa and Ab are shared by a high proportion of allogeneic HLA-A2-positive melanoma lines. HLA-A2.1 and total HLA class I molecules have now been purified from SK29-melanoma cells using affinity chromatography an…
