Infectivity of amastigotes of Trypanosoma cruzi.
The infectivity amastigotes of Trypanosoma cruzi, isolated from the supernatant of the J774G8 macrophage-like cell line infected with trypomastigotes to normal macrophages in vitro was tested. After a period of 1 h of T. cruzi-macro¬ phage interaction about 2% of the mouse peritoneal macrophages had ingested amastigotes. In contrast 12% of the macrophages had ingested epimastigotes. Treatment o...
متن کاملTrypanosoma cruzi: Role of δ-Amastin on Extracellular Amastigote Cell Invasion and Differentiation
Trypanosoma cruzi is a protozoan parasite that comprises different phylogenetic groups and is the causative agent of Chagas' disease. Different T. cruzi strains present differences in infectivity in in vitro and in vivo experimental models, which are likely related to the expression of different virulence factors. Amastin is a surface glycoprotein abundantly expressed on the intracellular mamma...
متن کاملGlycosylphosphatidylinositols are required for the development of Trypanosoma cruzi amastigotes.
Induction of a glycosylphosphatidylinositol (GPI) deficiency in Trypanosoma cruzi by the heterologous expression of Trypanosoma brucei GPI-phospholipase C (GPI-PLC) results in decreased expression of major surface proteins (N. Garg, R. L. Tarleton, and K. Mensa-Wilmot, J. Biol. Chem. 272:12482-12491, 1997). To further explore the consequences of a GPI deficiency on replication and differentiati...
متن کاملTrypanosoma cruzi extracellular amastigotes and host cell signaling: more pieces to the puzzle
Among the different infective stages that Trypanosoma cruzi employs to invade cells, extracellular amastigotes (EAs) have recently gained attention by our group. This is true primarily because these amastigotes are able to infect cultured cells and animals, establishing a sustainable infective cycle. EAs are thus an excellent means of adaptation and survival for T. cruzi, whose different infect...
متن کاملERM Proteins Play Distinct Roles in Cell Invasion by Extracellular Amastigotes of Trypanosoma cruzi
The protozoan parasite Trypanosoma cruzi is the causative agent of Chagas' disease. In mammalian hosts, T. cruzi alternates between trypomastigote and amastigote forms. Additionally, trypomastigotes can differentiate into amastigotes in the extracellular environment generating infective extracellular amastigotes (EAs). Ezrin-radixin-moesin (ERM) are key proteins linking plasma membrane to actin...
