Trypanosoma 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 کاملCell signaling during Trypanosoma cruzi invasion
Cell signaling is an essential requirement for mammalian cell invasion by Trypanosoma cruzi. Depending on the parasite strain and the parasite developmental form, distinct signaling pathways may be induced. In this short review, we focus on the data coming from studies with metacyclic trypomastigotes (MT) generated in vitro and tissue culture-derived trypomastigotes (TCT), used as counterparts ...
متن کاملFormation and remodeling of inositolphosphoceramide during differentiation of Trypanosoma cruzi from trypomastigote to amastigote.
Differentiation of Trypanosoma cruzi trypomastigotes to amastigotes inside myoblasts or in vitro, at low extracellular pH, in the presence of [(3)H]palmitic acid or [(3)H]inositol revealed differential labeling of inositolphosphoceramide and phosphatidylinositol, suggesting that a remodeling process takes place in both lipids. Using (3)H-labeled inositolphosphoceramide and phosphatidylinositol ...
متن کاملCell-substrate adhesion during Trypanosoma cruzi differentiation
The transformation of Trypanosoma cruzi epimastigotes to the mammal infective metacyclic trypomastigotes (metacyclogenesis) can be performed in vitro under chemically defined conditions. Under these conditions, differentiating epimastigotes adhere to a surface before their transformation into metacyclic trypomastigotes. Scanning and transmission electron microscopy of adhered and non-adhered pa...
متن کاملEcto-phosphatase activities on the cell surface of the amastigote forms of Trypanosoma cruzi.
Live Trypanosoma cruzi amastigotes hydrolyzed p-nitrophenylphosphate (PNPP), phospho-amino-acids and 32P-casein under physiologically appropriate conditions. PNPP was hydrolysed at a rate of 80 nmol.mg-1.h-1 in the presence of 5 mM MgCl2, pH 7.2 at 30 degrees C. In the absence of Mg2+ the activity was reduced 40% and we call this basal activity. At saturating concentration of PNPP, half-maximal...
