Summary
Dr. Poon's research into the mechanism of cell death reveals that what was long thought a random process actually has signs of regulation. In this podcast, you'll learn:
- What about the process signifies regulation.
- What cells release in these extracellular vesicles when they die.
- Why understanding the process of cell death in disease settings may lead to disease-fighting drugs.
Dr. Ivan Poon of La Trobe University is a Senior Research Fellow in biochemistry and genetics. He specializes in extracellular vesicles and cell turnover, or the mechanisms of cell death. In this discussion, he explains his focus on trying to understand what happens when cells die. The amount of energy a cell puts into generating small vesicles, or apoptotic bodies, during turnover is significant. Therefore, he and other researchers are studying why cells invest in this process.
While researchers have known the basics of cell death for decades, only recently has this mechanism of cell death process been understood as highly regulated rather than random. Furthermore, each cell type follows a different process. Monocytes, for example, form a string-like protrusion like a beaded necklace that then generates apoptotic bodies.
Most important for Dr. Poon is to understand the molecular mechanism of this process—what controls it. The answers may enable special treatment for diseases including drugs that either inhibit or accelerate cell deaths depending on the process needed to regain health.

| 1:09.4 | I have Ivan Kuhn, he's a senior research fellow in biochemistry and genetics at |
| 1:14.3 | Latrobe University. We're gonna be talking about extracellular |
| 1:18.2 | vesicles and you know what happens as part of cell turnover and other things in the body so |
| 1:24.2 | I haven't thanks for coming yeah thanks for inviting yeah tell me a little bit about |
| 1:28.6 | your research what's the focus of it yeah so the focus of our work is trying to |
| 1:32.4 | understand what happens to dying cells, you know, when they die, in particular the process of when they die, they will actually undergo a fragmentation process where they would generate small |
| 1:43.7 | vesicles called a top-like bodies and what we're interested is you know why when |
