Additional remarks phenotype

Mutant/mutation
The mutant lacks expression of macrophage migration inhibitory factor (MIF).

Protein (function)
Macrophage migration inhibitory factor (MIF) is a mammalian cytokine that participates in innate and adaptive immune responses. Homologues of mammalian MIF have been discovered in parasite species (nematodes and malaria parasites).

Phenotype
Asexual blood stage growth/multiplication (parasitemia) in BALB/c mice was not different from wild type parasites

Additional information
Evidence is presented that PyMIF could increase the secretion of pro-inflammatory factors by eliciting the CD11b+Ly6C+ cells accumulated in the spleen of infected mouse.

Other mutants
