Pool-priming: A means of generating T lymphocytes cytotoxin to tumour or virus-infected cells.

It is proposed that cells cytotoxic for autologous or syngeneic tumour cells can be produced in vitro by sensitisation of lymphocytes to a pool of normal cells from 20 unrelated individuals. Restriction on molecules that can serve as cytotoxic determinants (C.D.), may explain why a random pool of cells from 20 people could present essentially all of the determinants (C.D.) may explain why a random pool of occur because of extensive cross-reactivity of antigens on tumour cells with normal alloantigens present in the stimulating pool.
