Analysis of Peptidases in Non-Infected and Trypanosoma cruzi-Infected Mouse Embryo Hepatocyte Cells
Cellular and extracellular peptidase profiles from non-infected and Trypanosoma cruzi-infected hepatocyte cell cultures were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) containing different copolymerized proteins as substrates. A 100 kDa metallopeptidase activity was detected in the cellular extracts and in the culture supernatant fluids of both systems...
متن کاملCharacterization of [Ca2+]i responses in primary cultures of mouse cardiomyocytes induced by Trypanosoma cruzi trypomastigotes.
Trypanosoma cruzi, the protozoan responsible for Chagas disease, employs distinct strategies to invade mammalian host cells. In the present work we investigated the participation of calcium ions on the invasion process using primary cultures of embryonic mice cardiomyocytes which exhibit spontaneous contraction in vitro. Using Fura 2-AM we found that T. cruzi was able to induce a sustained incr...
متن کاملIn vitro multiplication of Toxoplasma gondii and Trypanosoma cruzi in mouse, rat, and hamster astrocytes.
The infection and multiplication of Toxoplasma gondii and Trypanosoma cruzi were compared in primary cultures of white rat, mouse and hamster astrocytes. These cells were cultured on cover slides and infected with T. gondii tachyzoites or T. cruzi blood trypomastigotes. Results show that hamster astrocytes are more susceptible to the multiplication of both parasites than rat and mouse cells. Th...
متن کاملEnhancement of NMRI Mouse Embryo Development In vitro
Most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. The general use of NMRI outbred mice is a model for toxicology, teratology and pharmacology. NMRI mouse embryo exhibit the two-cell block in vitro. The objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...
متن کاملDifferential tissue tropism of Trypanosoma cruzi strains: an in vitro study.
We have previously demonstrated selection favoring the JG strain of Trypanosoma cruzi in hearts of BALB/c mice that were chronically infected with an equal mixture of the monoclonal JG strain and a clone of the Colombian strain, Col1.7G2. To evaluate whether cell invasion efficiency drives this selection, we infected primary cultures of BALB/c cardiomyocytes using these same T. cruzi population...
