Mechanism of Interferon Action
The double-stranded RNA (dsRNA)-dependent protein kinase which catalyzes the phosphorylation of ribosome-associated protein Pl and the a subunit of eukaryotic protein synthesis initiation factor 2 (eIF-2) was purified and characterized from mouse fibroblast L929 cells treated with either natural or recombinant interferon and from untreated cells. The dsRNA-dependent Pl/eIF-2a kinase was purifie...
متن کاملStudies on the Mechanism of Interferon Action
Interferon does not inactivate viruses or viral RNA. Virus growth is inhibited in interferon-treated cells, but apart from conferring resistance to virus growth, no other effect of interferon on cells has been definitely shown to take place. Interferon binds to cells even in the cold, but a period of incubation at 37 degrees C is required for development of antiviral activity. Cytoplasmic uptak...
متن کاملOn a possible mechanism of action of interferon.
The effect of interferon on the ESR spectra of erythrocytes treated with ascorbic acid has been investigated. This model system has been chosen since it represents identically the spectra obtained in cases with acute lymphatic leukemia. The data obtained show that small interferon concentrations increase, while larger concentrations decrease the effect produced by ascorbic acid resulting, final...
متن کاملMechanism of Action of the Thyroid Hormone on the Heart
SUMMARY The foliowing cardiac effects may be attributed to thyroxin: 1-Thyroxin augments all anaerobic processes in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...
متن کاملAntibacterial Activity of Polypyrrole-Chitosan Nanocomposite: Mechanism of Action
Polypyrrole-chitosan nanocomposite (PPy-CTN) was synthesized by dispersion polymerization of PPy in presence of CTN. Preparation of spherical PPy nanoparticles that were successfully covered with a thin layer of chitosan was confirm by transmission electron microscopy (TEM) technique. Characterization techniques also revealed the presence of CNT in the polymer matrix and its presence was confir...
