Hypothesis
This study investigates the effects of elevated plasma glucose levels during diabetes on leukocyte recruitment and function in established models of inflammation.
Conclusion
Despite increased leukocyte recruitment, diabetic mice showed impaired ability to clear bacterial infections due to decreased phagocytic ability of leukocytes.
Supporting Evidence
- Diabetic mice had increased numbers of adherent and emigrated leukocytes compared to control mice.
- Alloxan-treated mice showed a 50% decrease in phagocytic ability of leukocytes.
- Despite more leukocytes, diabetic mice had a longer duration of bacterial infection.
Takeaway
Mice with diabetes have more white blood cells at the infection site, but they can't fight off bacteria as well as healthy mice.
Methodology
Diabetes was induced in mice using alloxan or a high-fat diet, and leukocyte recruitment was studied using intravital microscopy.
Potential Biases
Potential bias in the interpretation of leukocyte function due to the artificial induction of diabetes.
Limitations
The study was conducted in mouse models, which may not fully replicate human diabetes conditions.
Participant Demographics
C57BL/6 male mice were used in the study.
