The Toxoplasma rhoptry protein ROP55 is a major virulence factor that prevents lytic host cell death
Grilo Ruivo M, Shin J, Lenz T, Matsuno S, Yanes K, Graindorge A, et al.
Nat Commun
. 2025 Jan;
16(1):709.
PMID: 39814722
Programmed-cell death is an antimicrobial defense mechanism that promotes clearance of intracellular pathogens. Toxoplasma counteracts host immune defenses by secreting effector proteins into host cells; however, how the parasite evades...

PMID: 36245278
Apicomplexan parasites possess secretory organelles called rhoptries that undergo regulated exocytosis upon contact with the host. This process is essential for the parasitic lifestyle of these pathogens and relies on...

PMID: 35817892
Apicomplexan parasites secrete contents of the rhoptries, club-shaped organelles in the apical region, into host cells to permit their invasion and establishment of infection. The rhoptry secretory apparatus (RSA), which...
