The T cell receptor on T cells might recognize antigens derived from mutated proteins in cancer cells. Once a foreign “non-self” antigen is detected, the T cell will kill the cancer cell. Credit: Matthias Leisegang.
T cell therapies with less side effects. An international team has successfully modified immune cells to recognize and specifically target tumor cells in mice. Cancer treatments based on the findings would likely have fewer side effects than standard therapies. Although T cells migrate into tumors and recognize antigens, the defense mechanism seems to fail during the formation of tumors. T cells in the tumors are usually inactive and therapeutically almost useless...
