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...
