ROP16 Promotes Epithelial‐Mesenchymal Transition‐Like Changes in Ocular Toxoplasmosis via STAT3 and TGF‐β1 Pathways

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Toxoplasmosis is a globally significant infectious disease, affecting approximately one‐third of the world’s population. Ocular toxoplasmosis (OT) is a major and vision‐threatening clinical manifestation. However, its pathogenesis remains elusive, and effective targeted therapies are unavailable. This study demonstrates that Toxoplasma gondii infection

Protective Immunity Induced by DNA Vaccines Encoding TgGRA47 and TgGRA72 Against Toxoplasma gondii Infection in BALB/c Mice

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Toxoplasma gondii (T. gondii) is a protozoan parasite that lives inside cells and causes zoonotic diseases in the vast majority of homeothermic vertebrates, such as humans. Despite the critical biological roles of TgGRA47 and TgGRA72 in the determination of T.

The Toxoplasma gondii Rhoptry Kinome Is Essential for Chronic Infection

open access: yesmBio, 2016
Ingestion of the obligate intracellular protozoan parasite Toxoplasma gondii causes an acute infection that leads to chronic infection of the host. To facilitate the acute phase of the infection, T.

Plasmodium yoelii: identification of a gene encoding a putative ADP-ribosylation factor-1 GTPase-activating Protein, PyAG1

open access: yesMemorias do Instituto Oswaldo Cruz, 2000
The PyAG1 gene, identified by the screening of a Plasmodium yoelii genomic DNA library with a rhoptry-specific Mab, encodes a protein with a zinc finger structure immediately followed by the consensus sequence of the Arf GAP catalytic site.

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire

open access: yesPROTEOMICS, Volume 25, Issue 21-22, Page 253-276, November 2025.
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...

Characterization of SnROP9, a rhoptry protein homologue of Sarcocystis neurona that is expressed in lifecycle stages lacking rhoptry organelles

open access: yesInternational Journal for Parasitology
Proteins released by the club-shaped, apically located, specialized secretory organelles called rhoptries play an essential role in host cell invasion and intracellular survival of apicomplexans. Sarcocystis neurona, the apicomplexan responsible for equine protozoal myeloencephalitis (EPM), lacks rhoptries in its asexual developmental stages, viz ...

The Plasmodium falciparum rhoptry bulb protein RAMA plays an essential role in rhoptry neck morphogenesis and host red blood cell invasion.

open access: yes, 2020
The malaria parasite Plasmodium falciparum invades, replicates within and destroys red blood cells in an asexual blood stage life cycle that is responsible for clinical disease and crucial for parasite propagation.

Binding of Plasmodium falciparum Rhoptry Proteins to Mouse Erythrocytes and Their Possible Role in Invasion

open access: yes, 1990
Rhoptry proteins of Plasmodium falciparum merozoites, of 140, 130, and 110 kDa, identified by co-precipitation with Mab.1B9, bind selectively to mouse erythrocytes and reticulocytes.

Acidic compartments and rhoptry formation in Toxoplasma gondii

open access: yesParasitology, 1998
DAMP (3-(2,4-dinitroanilino)-3′amino-N-methyldipropylamine), which differentially accumulates in acidic compartments, was used to identify such compartments in Toxoplasma gondii tachyzoites at the electron microscope level. In both free tachyzoites and dividing intracellular parasites the only sites of DAMP accumulation were mature and forming ...
