Autophagy is your cells' garbage disposal system, clearing damaged mitochondria and worn-out proteins. When it works well, your cells produce more energy and function better. If autophagy fails, cellular trash builds up and slows everything down.
Autophagy is specifically, first off, a process that is part of the blueprint of how our cells are made to work. So if we think about cells and autophagy as a part of the way the cell is set up to operate normally, whether that cell is a muscle cell or a cell of our digestive tract or any other cell for the most part, it has things that it is supposed to do. So the normal blueprint then is the cell does whatever its business is. So if it's a GI tract cell, it does that. If it's a muscle cell, it does muscle business, right? So it does its business, but it also maintains itself through a number of means. So there's the energy-producing mitochondrial part we talk a lot about. There's the other cell organelles that help out with cell division and all of the reproduction of the cell. There's the cell membrane, the part around the outside that helps hold the cell together and signaling and all that business. But then there's other mechanisms within the cell, one big one being autophagy, which is essentially Essentially maintenance and cleaning of the cell. Now, autophagy kind of sort of literally translates to cell eating, autophagy. We aren't always eating our cell up, but the maintenance might require the cell being able to do things that are going to go after dysfunctional or damaged or used up parts of the cell so that the cell isn't carrying a bunch of garbage around. So it's sort of like if you, as we all do, have garbage that you collect in your house, a lot of times it's in the kitchen and we go in and the garbage basket is filling up. If we take the garbage out, we don't tend to smell the garbage. We don't tend to see the garbage. We don't tend to have bugs come in or vermin or whatever. If we don't have a strategy for taking the garbage out of the house and, you know, putting it wherever the garbage goes outside of your house, and our strategy is just to keep throwing the garbage on top of the garbage can and pretty soon it overflows, that's like a cell that has not done autophagy. And so in your house, what would happen is you'd see the garbage, you'd start to smell the garbage, and then other creatures that like garbage would come there. Could be bugs, could be rats, mice, cockroaches, whatever. Things you may not want in your house. Well, in your cell, when you overflow the garbage can and the autophagy is not working very well, kind of the same thing happens, although we don't get, you know, cockroaches and things going on. And we usually don't smell the cell going badly. Kind of the similar processes go on with lack of autophagy. So that might mean then if my garbage is building up that my mitochondria start to slow down. That actually happens. It might mean that the cell reproduction organelles and mechanisms slow down, right? Or the cell gets very dysfunctional in one of its metabolic processes. The garbage can do that. The garbage might get so bad that the cell membranes and their communication get disrupted. So autophagy is very important, but it's essentially Taking the garbage out. Now, if a cell gets to the end of its lifespan or it's time for it to divide, or it's just too dirty, too full of junk, a full-scale cell autophagy will go on and then it will be, uh, the cell will be removed. That's full-scale autophagy. So when you activate autophagy, you wind up helping to take the garbage out, which then increases your ability to create energy and increases the ability for the cell to operate at its maximum normal function.
