The recent advances were reviewed in the studies of microneme protein (MIC) and it is concluded that MIC plays an important role during host cell invasion and it is potential candidate for the development of vaccines against toxoplasmosis. The article makes a literature review about the microneme protein of the Toxoplasma gondii,which providing the theoritical basis for the research of vaccines against toxoplasmosis.
