Rodrigue Houngue identifies TgREMIND as a therapeutic target to fight toxoplasmosis in Benin

The thesis of Rodrigue Houngue, defended in 2023 at the French Alternative Energies and Atomic Energy Commission, reveals that the TgREMIND protein is essential for the biogenesis of secretory organelles in Toxoplasma gondii, the parasite responsible for toxoplasmosis. This discovery paves the way for targeted treatments for this growing infection in Benin.

Rodrigue Houngue's research focuses on Toxoplasma gondii, a parasite causing toxoplasmosis, a disease affecting both humans and animals. Understanding the molecular mechanisms of this infection is crucial for developing new therapeutic strategies. The TgREMIND protein has been identified as a key regulator in the biogenesis of secretory organelles, essential for the parasite's virulence.

By creating a TgREMIND knock-out mutant, researchers observed significant morphological and functional defects, affecting the parasite's ability to invade. Bioinformatic analysis, Lipid Overlay assays, and confocal microscopy methods made it possible to explore TgREMIND's interactions with other proteins, highlighting its role in intracellular trafficking.

The results of this research suggest that developing treatments targeting TgREMIND could offer an effective solution against toxoplasmosis. Decision-makers should consider this opportunity to invest in promising research, in order to respond to the rise in infection cases and meet pressing therapeutic needs.

« "The absence of TgREMIND leads to significant morphological and functional defects, affecting the parasite's ability to invade its hosts," says Rodrigue Houngue. »

« "This research highlights therapeutic innovation opportunities for decision-makers, by targeting specific mechanisms such as TgREMIND," notes the Lektaris team. »
