Lymphocytes incubated in the presence of IL-2 lose the capacity for chemotaxis but acquire antitumor activity

详细

Naïve non-activated lymphocytes are capable of releasing the chemoattractant complex Tag7–Mts1 and can migrate along the gradient of its concentration. After activation of these cells by IL-2, they acquire the abilities to kill tumor cells and to release the cytotoxic Tag7–Hsp70 complex, which is accompanied by a loss of both the Tag7–Mts1-mediated lymphocyte chemotaxis and the ability to release this chemoattractant into the conditioned medium.
