The Histidine Ammonia Lyase of Trypanosoma cruzi is Involved in Acidocalcisome Alkalinization and is Essential for Survival under Starvation Conditions (2021)
Journal Article
Mantilla, B., Azevedo, C., Denny, P., Saiardi, A., & Docampo, R. (2021). The Histidine Ammonia Lyase of Trypanosoma cruzi is Involved in Acidocalcisome Alkalinization and is Essential for Survival under Starvation Conditions. mBio, 12(6), https://doi.org/10.1128/mbio.01981-21

Trypanosoma cruzi, the agent of Chagas disease, accumulates polyphosphate (polyP) and Ca2+ inside acidocalcisomes. The alkalinization of this organelle stimulates polyP hydrolysis and Ca2+ release. Here, we report that histidine ammonia lyase (HAL),...

Chalcones identify cTXNPx as a potential antileishmanial drug target (2021)
Journal Article
Escrivani, D. O., Charlton, R. L., Caruso, M. B., Burle-Caldas, G. A., Borsodi, M. P. G., Zingali, R. B., …Steel, P. G. (2021). Chalcones identify cTXNPx as a potential antileishmanial drug target. PLoS Neglected Tropical Diseases, 15(11), Article e0009951. https://doi.org/10.1371/journal.pntd.0009951

With current drug treatments failing due to toxicity, low efficacy and resistance; leishmaniasis is a major global health challenge that desperately needs new validated drug targets. Inspired by activity of the natural chalcone 2’,6’-dihydroxy-4’-met... Read More about Chalcones identify cTXNPx as a potential antileishmanial drug target.

Quantitative Proteomics Reveals that Hsp90 Inhibition Dynamically Regulates Global Protein Synthesis in Leishmania mexicana (2021)
Journal Article
Karunakaran, K., Sundriyal, S., Perera, H., Cobb, S. L., & Denny, P. W. (2021). Quantitative Proteomics Reveals that Hsp90 Inhibition Dynamically Regulates Global Protein Synthesis in Leishmania mexicana. mSystems, https://doi.org/10.1128/msystems.00089-21

Heat shock protein 90 (Hsp90) is a conserved molecular chaperone responsible for the folding and maturation of nascent proteins. Hsp90 is regarded as a master regulator of protein homeostasis in the cell, and its inhibition affects the functions of a...
