Word: Opsonisation
Definition:
Opsonisation is a noun that refers to a process in the immune system. It happens when special proteins, called opsonins, attach to invading microorganisms (like bacteria or viruses). This makes it easier for certain cells in the body, known as phagocytes, to recognize and consume these microorganisms. In simpler terms, opsonisation helps the body fight off infections by marking harmful germs for destruction.
Usage Instructions:
Use "opsonisation" when discussing topics related to biology, immunology, or medicine. It’s a technical term, so it's usually found in academic texts or discussions about the immune system.
Example Sentence:
"During opsonisation, the opsonins coat the bacteria, making it easier for phagocytes to identify and destroy them."
Advanced Usage:
In more advanced discussions, you might encounter terms like "opsonic activity" or "opsonic antibodies," which refer to the specific actions or antibodies involved in the opsonisation process.
Word Variants:
- Opsonin (noun): The protein that attaches to pathogens during opsonisation. - Opsonize (verb): The action of marking microorganisms for destruction by the immune system.
