What are cathepsins?

Cathepsins are like tiny cleaners inside your body that help break down old stuff so new stuff can take its place.

Imagine you have a toy box full of toys. Over time, some toys get broken or worn out. Instead of throwing them away, your body uses cathepsins, which work like little helpers who come in and fix or clean up the mess. They do this by breaking down big pieces into smaller ones, just like you might break apart a puzzle to make it easier to solve.

Think of cathepsins as special tools that can cut through things like paper or plastic, but instead of paper or plastic, they're cutting through parts of your cells. This helps keep everything running smoothly inside your body, just like how cleaning up your toy box keeps you happy and ready for playtime.

When these tiny cleaners do their job well, it means your body can stay healthy and strong, kind of like how a tidy room makes playing more fun!
