Generation of HLA-B55 restricted T lymphocyte mediated cytotoxicity against autologous LCL. 1994

Department of Tumor Biology, Karolinska Institute, Stockholm, Sweden.

The lymphocytes of one HLA-A11 positive individual (A1, A11, B49, B55) were stimulated in vitro with the autologous EBV transformed lymphoblastoid cell line (LCL). The culture contained HLA-A1, A11 and B55 restricted, LCL selective cytotoxic T cells (CTLs). In the T cell culture stimulated four times, the lysis of A11 and B55 carrying targets suggested that the subsets of the two latter CTL types had similar size. After further stimulations the B55 restricted CTLs were enriched in the culture. Earlier results suggested that in HLA-A11 positive individuals the A11-restricted LCL-selective CTL subset dominates. The sensitivity of a target panel including Burkitt lymphoma (BL) lines suggested that the peptide presented by the B55 molecule differs in A and B type EBV strain carrying cells.

UI	MeSH Term	Description	Entries
D002461	Cell Line, Transformed	Eukaryotic cell line obtained in a quiescent or stationary phase which undergoes conversion to a state of unregulated growth in culture, resembling an in vitro tumor. It occurs spontaneously or through interaction with viruses, oncogenes, radiation, or drugs/chemicals.	Transformed Cell Line,Cell Lines, Transformed,Transformed Cell Lines
D004854	Herpesvirus 4, Human	The type species of LYMPHOCRYPTOVIRUS, subfamily GAMMAHERPESVIRINAE, infecting B-cells in humans. It is thought to be the causative agent of INFECTIOUS MONONUCLEOSIS and is strongly associated with oral hairy leukoplakia (LEUKOPLAKIA, HAIRY;), BURKITT LYMPHOMA; and other malignancies.

D013602	T-Lymphocytes, Cytotoxic	Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.

D015234	HLA-A Antigens	Polymorphic class I human histocompatibility (HLA) surface antigens present on almost all nucleated cells. At least 20 antigens have been identified which are encoded by the A locus of multiple alleles on chromosome 6. They serve as targets for T-cell cytolytic responses and are involved with acceptance or rejection of tissue/organ grafts.	Antigens, HLA-A,HLA-A,Antigens, HLA A,HLA A Antigens
D015235	HLA-B Antigens	Class I human histocompatibility (HLA) surface antigens encoded by more than 30 detectable alleles on locus B of the HLA complex, the most polymorphic of all the HLA specificities. Several of these antigens (e.g., HLA-B27, -B7, -B8) are strongly associated with predisposition to rheumatoid and other autoimmune disorders. Like other class I HLA determinants, they are involved in the cellular immune reactivity of cytolytic T lymphocytes.

D016130	Immunophenotyping	Process of classifying cells of the immune system based on structural and functional differences. The process is commonly used to analyze and sort T-lymphocytes into subsets based on CD antigens by the technique of flow cytometry.
