Plasmodium
Plasmodium parasites invade erythrocytes to access nutrients and occupy a protected intracellular niche[1]. Mechanistically, P. falciparum merozoite invasion depends on ligand-receptor interactions and regulated microneme and rhoptry secretion[2]. The apicoplast supports blood-stage growth mainly through isoprenoid precursor biosynthesis, shown by chemical rescue of parasites lacking this organelle[3]. Apicoplast-derived isoprenoids also support GPI-anchor biosynthesis, egress, and invasion in P. falciparum[4]. Compared with related apicomplexan parasites, malaria parasites use conserved host-cell entry logic but species-specific ligand-receptor interactions[1]. For experimental applications, apicoplast translation inhibitors and aminoacyl-tRNA synthetase inhibitors provide tools to test delayed death, organelle maintenance, and parasite viability[5][6].
