Can an injectable particle help supercharge your T cells? Elizabeth Tracey reports

Card T cells are a type of immune cell that have proven very effective for treating some

types of cancer, yet limitations to their use exist.

Biomedical engineering expert Jordan Greene at Johns Hopkins says limitations including

lengthy time and expense in having to produce card T's outside the body can be overcome

by stimulating T cells with a particle he and his team have created.

It's a polymer, it's a polyester.

You might be familiar with some other polyesters used in medicine.

For example, if you've had biodegradable sutures, biodegradable stitches where those were

put in but then over time they dissolved and so they'd have to be taken out again.

This is very similar except it's designed to degrade even more quickly.

How would be personalized is potentially the type of cargo that's inside of the particle.

It could be a type of cargo that can work broadly across a lot of people with the same

disorder or it could be a type of cargo that's more personalized for one specific, for example,

cancer.
