Good news, everyone!
"Researchers added one gene to make the T cells attack cancer, but they also used CRISPR to delete a different gene, called PD-1, which can act as a brake on the immune system’s defenses.
Pharmaceutical drugs that inhibit PD-1, known as immunotherapies, have been dramatically effective in treating a few cancers. Now the idea is to install the same capacity directly into the DNA of T cells."
