IMMUNOLOGIC INHIBITORY FACTOR IN NASOPHARYNGEAL CARCINOMA (NPC): EFFECT OF THE CULTURE SUPERNATANT OF NPC CELL LINE ON cAMP, IL-2, AND IL-2 RECEPTOR IN LYMPHOCYTES
This paper reports on the effect of the culture supernatant of NPC cell line (CNE-2S) (400μl/mll) on cAMP, IL-2 and IL-2 receptor in normal lymphocyts. The cAMP levels of lymphocytes from n cases was 13.77± 4.92pm/l×108. With lymphocytes suspensives added to the CNE-2S, the cAMP levels was increased to 26.1 ± 15,14Pm/l × 106 (P< 0.05). The activity of IL-2 of lymphocytes from 9 cases was 2048±1590 cpm. With lymphocytes added CNE-2S, the activity of IL-2 was decreased to 1236±761 cpm (P< 0.05). The activity ...
