First, the genetically engineered cells became CD8⁺ killer T cells that wiped out his leukemia. Then they transformed into a stable population of CD4⁺ helper T cells that continue to circulate in his body.

Specialized immune cells generated in vivo reduce cardiac scar tissue in mice, a new study shows.

Following on the success of CAR T cells used to treat cancers of the blood, researchers have launched a Phase 1 clinical trial of genetically modified macrophages to target solid tumors.

A trio of papers shows that specialized antibodies can direct T cells to destroy cells that display portions of mutant cancer-related proteins, as well as T cells that have become cancerous themselves.

When tumor cells are infected with an oncolytic virus carrying a modified CD19 gene, they become targets for CAR T cells engineered to recognize this molecular marker.

There’s a new cell-based cancer immunotherapy on the block.

A newly engineered CAR T cell that incorporates a peptide isolated from the venom of the deathstalker scorpion has broad brain tumor–binding capabilities that will be investigated in an upcoming clinical trial.

In the first clinical study of its kind in the US, researchers used CRISPR to modify CAR T cells to make them more potent against cancer, but the clinical benefits are unknown.

The immunotherapy induces a form of cell death in leukemia cells in mice that triggers cytokine release syndrome, a dangerous inflammatory reaction that occurs in some patients.

We may not have personal jetpacks yet, but the past decade has been marked by life-science revolutions, and the coming years have even more biological breakthroughs in store.

Scientists show the approach can kill cells that cause hardening of heart tissue in mice.

The company Cell Vault offers to hold consumers’ T cells for later use, but scientists suggest the service would benefit very few users.

About a quarter of lymphoma patients eligible for the cancer treatments are opting for experimental—and free—options instead.
