New research looks at why and what can be done to activate the cells to destroy tumors. Researchers say the failure of these immune cells to kill cancer may be due to different cell priming or suppressing mechanisms.
Researchers now say that they have found a method to activate the anti-cancer cells in mice. For the study, researchers took bone marrow from breast cancer patients and separated the anti-cancer cells. The cells were stimulated to become effective cancer killers. The activated cells were then injected into mice that had been previously implanted with tumors. Researchers report the activated T cells were effective at attacking the tumor and in reducing the tumor size.
Thus researchers say that cancer treatment using reactivated anti-cancer specific T cells from the patient's own body may be effective at reducing tumor size if more studies could be done to confirm the same.
