When they killed the animals a week later, they found that the virus had broken apart dystrophin in their hearts and that the membranes of heart cells infected with Coxsackie B virus were more permeable to blue dye than uninfected cells.
The audience is cast as visitors who have come to watch a volunteer, Lloyd Boyd (Logan Marshall-Green, deserving an actor's equivalent of the Purple Heart), be infected with various pathogens, including the Black Death and cholera — particularly fun, with Lloyd vomiting while writhing in pain from diarrhea on the toilet.
Earlier studies indicated that transgenic (tg) mice engineered to express prion protein (PrP) lacking the glycophosphatidylinositol (GPI−/−) membrane anchor formed abnormal proteinase-resistant prion (PrPsc) amyloid deposits in their brains and hearts when infected with the RML strain of murine scrapie.
The embryonic hearts were infected with lentivirus vectors expressing Nkx2.5, Tbx3, Gata4, and Tbx5 for 24 h with 5 × 10 transducing units/ml.
Others include toxocariasis, a parasitic worm infection transmitted from dogs and cats and thought to affect tens of millions of people, especially poor African-Americans; Chagas, a parasitic infection that may cause heart failure, infecting 300,000 across the country; as well as flu-like, mosquito-borne diseases such as dengue and chikungunya, which are growing threats in warmer climates.
When heart cells were infected with the virus they became smaller, thin and tapered as they acquired the "distinctive features of pacemaker cells", the report said.
After cultured rat heart cells were infected with the Coxsackie B virus, the amount of normal dystrophin declined within 3 days.
Compared with uninfected mice, we observed an approximately 10-fold catalase activity increase in the heart of AV.RSV.MCAT infected mice.
Parasitism and inflammatory infiltrate were more severe in the heart of Colombiana infected and/or reinfected animals.
Ultrastructural alterations found in epimastigotes treated with 3 confirmed extensive cytoplasm destruction in the parasites, whereas histopathological analysis of the hearts of mice infected and treated with 3 resulted in a decrease in cardiac damage.
