title: In vitro allostimulation of peripheral blood mononuclear cells generates autologous reactive T lymphocytes: analysis at the clonal level.
abstract: Cells from two siblings within family PER with a maternal crossing-over were used as responder and stimulator cells; they differed in class II MHC gene products. The responder cells were cloned and studied for their specificity. All the clones were T4+, most of them, were allospecific cytotoxic T-cell clones, some were only proliferative. Among the 62 clones that have been screened for their phenotype and function, we could expand, in our cloning system, two autoreactive T-cell clones specific for the self-class II MHC products. The results indicated that this autoreactivity was also observed in serum-free medium, which excludes any serum components susceptible to alter the self-class II MHC products. For the autorecognition, the two clones used the T3-Ti complex, and only one of them, the T4 structure.
