Microneme
Microneme
Microneme (pronunciation: /ˈmaɪkrəˌniːm/) is a specialized organelle found in apicomplexan parasites.
Etymology
The term "Microneme" is derived from the Greek words 'micros' meaning small and 'nema' meaning thread.
Definition
Micronemes are small, elongated vesicles that are distributed throughout the cytoplasm of the parasite. They are involved in the invasion of host cells by the parasite.
Function
Micronemes secrete proteins that facilitate the movement of the parasite and the invasion of host cells. These proteins are often referred to as microneme proteins or MICs.
