Immune killing activity of lymphocytes on Hela cells expressing interleukin-12 in vitro.
The killing effects of lymphocytes on Hela cells expressing interleukin-12 (IL-12) in vitro were explored. By using gene transfection technique, full length IL-12 gene was transfected into Hela cells. The expression of IL-12 in Hela cells was detected quantitatively by ELISA; Changes in killing effects of lymphocytes on Hela cells expressing IL-12 were observed by MTT. It was found that Hela cells could express IL-12 between 24 h and 72 h after transfection. Killing activity of lymphocytes on Hela cells expressing IL-12 was significantly enhanced. It was concluded by cell transfection technique, Hela cells could express IL-12 and were more easily killed by lymphocytes.
