Notes
Example Sentences
They found that in the absence of FOXO1, human CAR T cells lose their ability to form a healthy memory cell or protect against cancer in an animal model, supporting the notion that FOXO1 controls memory and antitumor activity.
They added, however, that after the pathogen is eliminated, effector cells can, in essence, change their minds and decide late to join the memory cell pool.
"What we've discovered," says Pobezinsky, "is that a tiny piece of miRNA, let-7, which has been handed down the evolutionary tree since the dawn of animal life, is highly expressed in memory cells, and that the more let-7 a cell has, the less chance that it will be tricked by cancerous tumor cells, and the greater chance it has of turning into a memory cell."
If the memory cell isn't tricked by the cancer, then it can fight and, crucially, remember what that cancerous cell looks like.
So the virus “is not in the background, messing up memory cell formation,†he said.
