Abstract:
Genetically engineered mice have been essential tools for elucidating the pathological mechanisms underlying human diseases. In the case of diseases caused by impaired desmosome function, mouse models have helped to establish causal links between mutations and disease phenotypes. This review focuses on mice that lack the desmosomal cadherins desmoglein 3 or desmocollin 3 in stratified epithelia. A comparison of the phenotypes observed in these mouse lines is provided and the relationship between the mutant mouse phenotypes and human diseases, in particular pemphigus vulgaris, is discussed. Furthermore, we will discuss the advantages and potential limitations of genetically engineered mouse lines in our ongoing quest to understand blistering skin diseases.
Insights
Genetically engineered mice lacking desmoglein 3 or desmocollin 3 reveal insights into desmosome function and blistering skin diseases like pemphigus vulgaris.
Area of Science:
- Cell Biology
- Dermatology
- Genetics
Background:
- Genetically engineered mice are crucial for studying human disease mechanisms.
- Impaired desmosome function causes various blistering skin diseases.
- Desmosomal cadherins, like desmoglein 3 and desmocollin 3, are vital for epithelial integrity.
Purpose of the Study:
- To review genetically engineered mouse models lacking desmoglein 3 or desmocollin 3.
- To compare the resulting phenotypes and their relevance to human diseases.
- To discuss the utility and limitations of these mouse models for understanding blistering skin diseases.
Main Methods:
- Focus on mouse models with genetic alterations in desmoglein 3 or desmocollin 3.
- Comparative analysis of observed phenotypes in different mouse lines.
- Correlation of mouse model phenotypes with human disease manifestations.
Main Results:
- Mice lacking desmoglein 3 or desmocollin 3 exhibit distinct blistering skin phenotypes.
- These models establish a link between specific desmosomal gene mutations and disease.
- Phenotypes provide insights into the role of desmosomes in epithelial barrier function.
Conclusions:
- Genetically engineered mice are valuable tools for dissecting desmosome-related diseases.
- These models facilitate understanding of pemphigus vulgaris and other blistering conditions.
- Further research using these models can advance therapeutic strategies for skin diseases.
