Figure 2. GA treatment of RRMS patients increases NK cell lysis of tumor target cells.

Figure 2

NK cells were isolated from MS patients either pre-treatment (Pre) or after several weeks of treatment (ranging from 1–48 weeks). These cells were activated in vitro for five days and then examined for their ability to lyse the leukemic cell line K562. Percent cytotoxicity is shown as mean ± SEM of four parallel experiments done from cells isolated from the same patient. P values compared lysis of tumor cells by NK cells isolated from GA-treated patients before (Pre) and weeks after treatment.
