Abstract:
As a tool to investigate physiological and pathological roles of cytokines, gene manipulation techniques have been applied to make mouse models having mutations in cytokine receptor genes. Functional pleiotropy and redundancy are two major characteristic features of cytokines. The latter feature is in part explained by the shared usage of a signal-transducing receptor component by several cytokine receptor complexes. In this article, studies with the help of gene manipulation techniques on a group of cytokine receptor complexes sharing the signal transducer, gp130, are reviewed. To investigate the in vivo roles of gp130, mice deficient for gp130 or having constitutively activated gp130 were made. Transgenic mice expressing a dominant-negative form of gp130 were produced as well. Observation from these mouse models and that from mice deficient for other gp130-related receptors and ligans are also reviewed in this article.
Insights
Gene manipulation in mice revealed the in vivo roles of gp130, a shared signal transducer for cytokine receptors. Studies using deficient and activated gp130 mouse models illuminate cytokine signaling pathways.
Area of Science:
- Immunology
- Molecular Biology
- Genetics
Context:
- Cytokines play crucial roles in physiological and pathological processes.
- Cytokine signaling is characterized by functional pleiotropy and redundancy.
- Shared receptor components, like gp130, contribute to cytokine redundancy.
Purpose:
- To review studies utilizing gene manipulation techniques to investigate the in vivo roles of the signal transducer gp130.
- To examine mouse models with gp130 deficiency, constitutive activation, or dominant-negative forms.
- To synthesize findings from gp130-related receptor and ligand knockout mice.
Summary:
- Gene manipulation in mice has been instrumental in dissecting cytokine receptor functions.
- Mouse models deficient for gp130 or exhibiting altered gp130 signaling provide insights into its physiological and pathological roles.
- Analysis of these models, alongside studies on related receptors and ligands, elucidates the complex network of cytokine signaling.
Impact:
