Insights
NOD mice show normal interferon-alpha/beta (IFN-alpha/beta) production but enhanced interferon-gamma (IFN-gamma) production compared to ICR mice. These findings suggest potential immune abnormalities in NOD mice related to IFN-gamma.
Area of Science:
- Immunology
- Virology
Background:
- Interferons (IFNs) are crucial cytokines in innate and adaptive immunity.
- NOD mice are a model for autoimmune diabetes, but their general immune responses require further characterization.
Purpose of the Study:
- To compare the production of interferon-alpha/beta (IFN-alpha/beta) and interferon-gamma (IFN-gamma) in NOD and ICR mice.
- To investigate potential immune dysregulation in NOD mice.
Main Methods:
- In vitro stimulation of spleen cells with various mitogens and viruses (NDV, Sendai virus, poly(I:C), LPS, Con A, PHA, PWM).
- In vivo induction of IFN production in BCG-sensitized mice using PPD.
- Quantification of IFN-alpha/beta and IFN-gamma levels.
Main Results:
- In vitro IFN-alpha/beta production was similar in NOD and ICR mice.
- In vitro IFN-gamma production was significantly higher in NOD mice compared to ICR mice.
- In vivo IFN-alpha/beta production was similar, but IFN-gamma production was elevated in NOD mice after BCG sensitization and PPD challenge.
Conclusions:
- NOD mice exhibit normal IFN-alpha/beta production.
- NOD mice display enhanced IFN-gamma production both in vitro and in vivo.
- These findings suggest specific abnormalities in IFN-gamma regulation in NOD mice, potentially contributing to their autoimmune characteristics.
Abstract:
The production of interferon-alpha/beta (INF-alpha/beta) and interferon gamma (IFN-gamma) in NOD and ICR mice was studied in vitro and in vivo. The in vitro IFN-alpha/beta production in the spleen cells of NOD mice, which were stimulated with either Newcastle disease virus (NDV), Sendai virus, poly(I:C) or lipopolysaccharide (LPS), was very similar to the IFN-alpha/beta production in the spleen cells of ICR mice. Contrastingly, the in vitro IFN-gamma production in the spleen cells of NOD mice, which were stimulated with either concanavalin A (Con A), phytohemagglutinin (PHA) or pokeweed mitogen (PWM), was greater than the IFN-gamma production in spleen cells of ICR mice. The in vivo IFN-alpha/beta production in NOD mice induced by NDV was also very similar to that in ICR mice, whereas the in vivo IFN-gamma production in the BCG-sensitized NOD mice, which was induced by purified protein derivative (PPD), was greater than that in the ICR mice. These results may indicate that NOD mice have abnormalities on the IFN-gamma production.
