iron treatment influenced the mlr in the following ways : ( 1 ) a variable degree of inhibition was observed which related to the dose of ferric-citrate used and to hla phenotype , ( 2 ) the responder but not the stimulator cells were affected , ( 3 ) no statistically significant differences were seen between female and male donor cells and ( 4 ) the mean percent response of cells from hla-a2 donors were significantly ( 0.005 less than p less than 0.01 ) less susceptible to iron exposure than those from non-hla-a2 individuals .
