PIR and infection: We compared the proteome of the acute-stage parasites with the proteome of the chronic-stage parasites to identify (1) PIR proteins that are highly expressed during the acute- and/or chronic-phases of blood-stage infection, and (2) their localisation on the iRBC (iRBC membrane/Host-Cell Cytoplasm (HCC), PV/PVM, Parasite Cytoplasm (PCyt) or Parasite Plasma Membrane (PPM)).
