Lu, Hong-Gang, Zhong, Li, De Souza, Wanderley, Benchimol, Marlene, Moreno, Silvia, Docampo, Roberto
The survival of a eukaryotic protozoan as an obligate parasite in the interior of a eukaryotic host cell implies its adaptation to an environment with a very different ionic composition from that of...
Chromosome Localization Changes in the Trypanosoma cruzi Nucleus
Faria, Marcella, Mortara, Renato A., Motta, Maria Cristina M., De Souza, Wanderley, Thiry, Marc, ...
Chromosome localization in the interphase nuclei of eukaryotes depends on gene replication and transcription. Little is known about chromosome localization in protozoan parasites such as...

3-Hydroxy-3-methyl-glutaryl-CoA reductase (HMGR) is a key enzyme in the sterol biosynthesis pathway, but its subcellular distribution in the Trypanosomatidae family is somewhat controversial....
Novel Azasterols as Potential Agents for Treatment of Leishmaniasis and Trypanosomiasis
Lorente, Silvia Orenes, Rodrigues, Juliany C. F., Jiménez, Carmen Jiménez, Joyce-Menekse, Miranda, Rodrigues, Carlos, Croft, Simon L., ...
This paper describes the design and evaluation of novel azasterols as potential compounds for the treatment of leishmaniasis and other diseases caused by trypanosomatid parasites. Azasterols are a...
Antileishmanial Activity of Parthenolide, a Sesquiterpene Lactone Isolated from Tanacetum parthenium
Tiuman, Tatiana Shioji, Ueda-Nakamura, Tânia, Garcia Cortez, Diógenes Aparício, Dias Filho, Benedito Prado, Morgado-Díaz, José Andrés, De Souza, Wanderley, ...
The in vitro activity of parthenolide against Leishmania amazonensis was investigated. Parthenolide is a sesquiterpene lactone purified from the hydroalcoholic extract of aerial parts of Tanacetum...
Cryptic Paraflagellar Rod in Endosymbiont-Containing Kinetoplastid Protozoa
Gadelha, Catarina, Wickstead, Bill, De Souza, Wanderley, Gull, Keith
Cilia and flagella are central to many biological processes in a diverse range of organisms. The kinetoplastid protozoa are very appealing models for the study of flagellar function, particularly in...
Role for a P-type H+-ATPase in the acidification of the endocytic pathway of Trypanosoma cruzi
Vieira, Mauricio, Rohloff, Peter, Luo, Shuhong, De Souza, Wanderley, Docampo, Roberto
Previous studies in Trypanosoma cruzi, the etiologic agent of Chagas disease, have resulted in the cloning and sequencing of a pair of tandemly linked genes (TcHA1 and TcHA2) that encode P...
