Conversation

I read an interesting article about properdin and its role in the immune system.

Really? I haven't heard much about it, what does it do?

It helps activate complement proteins, which is crucial for fighting infections.

That sounds important! I need to learn more about these proteins.

Root Explanation

Properdin is derived from the prefix 'pro-' (meaning for or in favor of) and the root 'perdin', which is a coined term in the context of immunology. The term 'properdin' refers to a protein that plays a role in the immune response, specifically in the complement system, enhancing the body's defense against pathogens.

Memory Tip

Think of 'pro-' meaning in favor of something, which helps you remember that properdin is a protein that supports the immune system.
