Sentences with phrase «used precancerous cells»

Not exact matches

Using animal models of precancerous polyps in the bowel, Chung and his team determined that certain types of immune cells within a chronically inflamed intestine can become rewired, causing them — paradoxically — to contribute to disease development rather than protect against it.

But, counter-intuitively, this mass cell death might be the very thing that makes the animals so long - lived: it could be a natural mechanism their bodies use to clear precancerous cells, stopping tumors in their tracks.

Two types of vaccines were used for the study: one constructed with genetically engineered DNA molecules that teach immune system cells to recognize premalignant cells expressing HPV16 E7 proteins, and one that is a non-infectious, engineered virus that targets and kills precancerous cells marked by HPV16 and HPV18 E6 and E7 proteins.
