  • Wow, Triangle Bob, this housewarming party turned out great! Everyone made it.

  • RhombusGreeg, Shrimpy Danielson, who appeared in like a couple of episodes 5 years agoand of course, the wonderful Circlia.

  • And me, Mocko! I just showed up because I'm lonely

  • Great, stay over there! Whoa! Everyone! Look out the window! There's a horde of glowing Ghouls

  • Triangle Bob, start boarding up the windows, and mewell, I'll do the most appropriate thing for this situation: make a Youtube video!

  • WhatKnowledge is power! Queue the intro!

  • Hey there! Welcome to Life Noggin!

  • These Glowing Ghouls exist in my world, but not in your human world, right? Well, kind of.

  • Your body actually produces a substance that glows and understanding it might be a key to treating age-related diseases.

  • Yeah, these two things are related, but to explain it more, we need to first talk about what happens when your body's recycling plant starts failing.

  • To keep us running properly, our cells process a lot of different materialslike proteins.

  • But eventually, these materials become damaged or are no longer needed.

  • Instead of just letting all this junk pile up, the lysosomes in our cells contain powerful chemicals called enzymes that break molecules apart so they can be reused.

  • Very resourceful humans. Good job!

  • But sometimes things go wrong

  • Lysosomes can be overloaded with wasteor the waste materials aren't brought to the lysosomes at all.

  • Excuse me, one second. Circlia, could you take care of them, please. Thanks, honey! You're the best.

  • One type of cellular junk is lipofuscin.

  • This is a yellowish-brown pigment made up of proteins, fatsand metals.

  • Scientists aren't sure exactly how it forms, but believe that one of the sources is damaged mitochondria.

  • It's okay, buddyYou don't always have to be the powerhouse.

  • Whatever its origin, lipofuscin seems to grow once formedgrabbing onto everything it comes in contact with.

  • And because it forms strong bondsit can't be removed from the cell.

  • As we age, lipofuscin accumulates

  • One group of scientists found that it occupies as much as 70% of the volume of brain cells of people over 100.

  • Oh, yeah. It also glows.

  • This is called autofluorescence and it happens when lipofuscin is exposed to blue or purple light.

  • These EDM-loving monsters in my world are definitely fluorescent, but if people are full of this glowing substance, why don't we see it everywhere?

  • I mean, 600 million years of animal lifeand deathon your planet would lead to a lot of undegraded lipofuscin, right?

  • Well, other organisms in your human world do have the enzymes needed to break lipofuscin and other stubborn junk down, such as microbes like bacteria.

  • There are plenty of these microbes in our soil that help decompose dead bodies! Fun!

  • And this, my flesh monsters with an expiration dateis what has inspired scientists to use these enzymes to treat age-related diseases.

  • Heythere's that tie-in I mentioned in the beginning of the vidoe.

  • It's all connected and it's all fascinating!

  • You see, when a cell's recycling system fails, and there's a build-up of junkthe cell can become dysfunctional.

  • This leads to age-related diseases like atherosclerosisParkinson's, Alzheimer's, and macular degeneration.

  • All of which are very bad.

  • But these diseases could be treated using new, engineered enzymes based off of microbes.

  • For instance, a team of researchers discovered an enzyme in mycobacteria that could be engineered to break down excess cholesterol.

  • This excess can cause atherosclerosis as it builds up and creates plaques that reduce blood flow or cause the artery to burst, leading to a blood clot.

  • When tested in mice, the cholesterol-degrading platform eliminated half of the pre-existing plaque in their cute little mouse aortas.

  • This and other lysosome-based treatment strategies are being funded by the SENS Research Foundation's LysoSENS research track

  • Oh hey! They sponsored this video!

  • So, if you're interested in learning more about them and their work, click the first link in the description right now.

  • So here's my question to you, the beautiful person watching:

  • If you could live to the age of 200 and you are completely healthy, would you do it?

  • What age would you even want to live to and what would you do with that extra time?

  • Let me know in the comments section below. I'm going to be gathering some responses for a future video!

  • As always, my name is Blocko. This has been Life Noggin. Don't forget to keep on thinking.

Wow, Triangle Bob, this housewarming party turned out great! Everyone made it.
