THE EFFECT OF SULFHYDRYL GROUPS ON PNEUMONIA VIRUS OF MICE (PVM)
1Hospital of The Rockefeller Institute for Medical Research.
Abstract:
Evidence is presented which indicates that PVM is affected adversely in concentrated lung tissue suspensions or in the presence of glutathione. Because iodoacetamide inhibits or eliminates these effects in a similar manner, it is concluded that sulfhydryl groups are essential to their development.
Insights
The study found that Pneumonia Virus of Mice (PVM) is harmed by concentrated lung tissue and glutathione. Sulfhydryl groups are essential for these adverse effects, as shown by iodoacetamide
Area of Science:
- Virology
- Cell Biology
- Biochemistry
Background:
- Pneumonia Virus of Mice (PVM) is a significant respiratory pathogen.
- Understanding PVM's interactions with host tissues is crucial for developing antiviral strategies.
Purpose of the Study:
- To investigate the adverse effects on PVM in concentrated lung tissue suspensions.
- To determine the role of glutathione and sulfhydryl groups in PVM's susceptibility.
Main Methods:
- PVM infectivity assays were performed in concentrated lung tissue suspensions.
- The influence of glutathione on PVM was assessed.
- The effect of iodoacetamide, a sulfhydryl inhibitor, was evaluated.
Main Results:
- PVM infectivity was adversely affected in concentrated lung tissue suspensions.
- Glutathione exacerbated these adverse effects on PVM.
- Iodoacetamide treatment inhibited or eliminated the detrimental effects observed.
Conclusions:
- Sulfhydryl groups are essential for the adverse effects observed on PVM in lung tissue suspensions.
- These findings suggest a potential mechanism for PVM's pathogenesis involving host cell components.
