Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

He'll go get exactly the ball that you just threw.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

He'll bring it back, but then he won't let it go.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

Same thing.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

So the sensor catches the protein, but it won't let it go.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

It's a very strong complex.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

Yeah, so we chose a diabetes model because, you know, diabetes and inflammation go hand in hand, right?

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

If your glucose is out of range, your inflammation is going to start to spike.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

So we thought that would be a good model.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

And, you know, we had rats that we allowed to fast and we could see that as they fasted, their pro-inflammatory cytokines would come down.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

We had animals that we would inject with insulin and we could see the pro-inflammatory markers come down even faster.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

Interestingly, when we injected the rats with insulin to kind of see how that would affect things, we actually saw a little spike in inflammation just from the needle prick.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

Like that's how good the resolution is.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

So that was very cool to see.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

Yeah.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

And then we also dose the rats with molecules that would make their inflammation spike, and we could absolutely see that.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

So we were able to convince ourselves and the folks that reviewed our paper that we really could watch inflammation in real time in a living animal.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

Oh, absolutely.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

I mean, the concept is to just, we're going to just go right alongside, you know, the way the CGMs have been developed.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

So sensor in the interstitial fluid, app on a phone, being able to track markers that will help us make lifestyle decisions, help us manage disease.

Ground Truths
Shana Kelley: Biosensors to Track Proteins and Inflammation in Our Blood in Real Time

And then there's also a whole set of research applications as well that I think will be really interesting.
