Engineering CAR NK Cells

Which CAR designs and engineering methods most reliably improve NK cells’ activity against cancer?

Following comparisons of CAR designs, added secreted proteins and non-viral engineering could reveal which modifications provide reproducible gains in antitumour activity.

Where it stands now

Main bottleneck

The bounded evidence does not establish which improvements extend beyond a particular CAR design or cancer target, or how non-viral engineering compares with other methods.

Watch next

A controlled comparison showing that a specific CAR design or non-viral engineering method reproducibly improves antitumour activity against a defined cancer target.

    Since the previous research note: Engineered natural killer cells deliver an extra protein to mouse breast tumors

    Previous expectation: Engineered natural killer cells might help patients with resistant HER2-positive breast cancer by combining tumour recognition with local delivery of an immune-inhibition-relieving protein.

    What this study adds: The June 2024 study compares seven CD19 receptor designs in cord-blood natural killer cells against leukaemia, distinguishing tumour-killing performance from persistence in mice. It does not test the earlier HER2-targeted delivery strategy or its forecast for resistant breast cancer.
