Production of LacZ Inducible T Cell Hybridoma Specific for Human and Mouse gp10025–33 Peptides

چکیده
Identification and quantification of immunogenic peptides and tumor-derived epitopes presented on MHC-I molecules are essential for basic studies and vaccines generation. Although lymphocytes derived from transgenic mice can serve as sensitive detectors of processes of antigen presentation and recognition, they are not always available. The use of cell lines might be extremely useful. In this study, we generated a lacZ inducible CD8⁺ hybridoma (BUSA14) capable of recognizing both human and mouse gp100₂₅₋₃₃ melanoma antigens presented on dendritic and tumor cell lines. This hybridoma expresses a variety of membranal T cell markers and secretes IL-2 and TNFα. Thus, BUSA14 offers a quantifiable, cheap and straightforward tool for studying peptide presentation by MHC-I molecules on the cell surface.

Objective(s) The main objective of this study was to investigate the status of chromosome stability in 3 human-mouse hybridoma cell lines over a period of time in various passages. Materials and Methods Metaphase spreads from 3 human-mouse cell lines (HF2X653, SPMO-4 and F3B6) that had been cultured in 4 successive passages, from 1 to 4 weeks, were prepared and analyzed. Metaphase chromosome...

A hybridoma clone designated 6G5 has been selected by fusion of mouse myeloma cell line Ag. 8653 with spleen cells from mice immunized with human peripheral blood mononuclear cells (PBMC). The antibody produced by this clone was found to be strongly reactive with four human B-cell lines in the conventional immunological assays. Despite the fact that expression of most B cell-associated mar...

The alpha/beta T-cell receptor a complex ligand formed by the association of antigenic peptides with molecules of the major histocompatibility complex (MHC). The inherent limitations of the conventional T-cell activation assays used to detect these peptide/MHC ligands have, until now, hampered the development of expression cloning systems for T-cell antigens. To overcome these limitations, we h...
