Researchers implanted human tumors into lab mice and studied the effects of this new antibiotic on the tumor. This antibody masked a protein flag on cancer cells that protect them from the immune system cells. This now allows the immune system cells to attack the tumor and break it down so it is not harmful anymore. So far they have tested ovarian, colon, bladder, brain, liver and prostate cancer samples with successful outcomes. As researchers began to test different animals not all cases were successful. The antibody did not harm the animal, but it did not reduce the tumor. On the other side, in the successful cases, after the tumor disappeared, the mice showed no negative side affects and the tumor did not return.
I found this very interesting because any advancement in cancer studies is one step closer to finding a cure for all cancers. This can be extremely useful for all types of cancer. The only concerning factor is, would the immune system being to attack cells that are suppose to be there? Is the immune system going to weaken as a side effect of the antibody? These questions will hopefully be answered after the human clinical trials begin.
