Male mouse submaxillary gland secretes highly toxic proteins
Experientia
|August 15, 1980
Abstract:
Submaxillary gland saliva induced by phenylephrine from male mice was highly toxic to guinea-pigs, rats and hamsters, whereas the toxicity was relatively low to mice. One of the toxic components in the saliva was isolated as a kallikrein-like enzyme.
Insights
Submaxillary gland saliva from male mice is highly toxic to other species but not mice. A kallikrein-like enzyme was identified as a key toxic component in this saliva.
Area of Science:
- Biochemistry
- Toxicology
- Mammalian Physiology
Background:
- Submaxillary gland saliva plays diverse physiological roles.
- Phenylephrine is a sympathomimetic agent that can stimulate salivary secretion.
- Species-specific toxicity of biological substances is a known phenomenon.
Purpose of the Study:
- To investigate the toxicity of phenylephrine-induced submaxillary gland saliva from male mice.
- To identify the toxic components within the saliva.
- To compare the toxicity across different rodent species.
Main Methods:
- Saliva was collected from male mice following phenylephrine administration.
- Toxicity assays were performed using guinea-pigs, rats, hamsters, and mice.
- Biochemical isolation techniques were employed to identify toxic components.
Main Results:
- Mouse submaxillary saliva exhibited high toxicity in guinea-pigs, rats, and hamsters.
- Mice showed significantly lower susceptibility to the saliva's toxic effects.
- A kallikrein-like enzyme was isolated as a major toxic factor in the saliva.
Conclusions:
- Submaxillary gland saliva from male mice contains potent toxins with species-specific effects.
- A kallikrein-like enzyme is a significant contributor to the observed toxicity.
- These findings have implications for understanding interspecies toxicological interactions and salivary biochemistry.
