Un modello di topo per patogeni indotta infiammazione cronica a siti locali e sistemici

Overview

This study presents a mouse model for investigating chronic inflammation induced by the oral infection of Porphyromonas gingivalis. The methodologies outlined allow for the assessment of both local and systemic inflammatory responses.

Key Study Components

Area of Science

• Neuroscience
• Immunology
• Infectious Diseases

Background

• Chronic inflammation is a significant health issue linked to various diseases.
• Animal models are essential for understanding host-pathogen interactions.
• Porphyromonas gingivalis is a key pathogen in periodontal disease.
• This model allows for the study of inflammation at both local and systemic levels.

Purpose of Study

• To examine the effects of microbial infection on chronic inflammation in vivo.
• To utilize a physiologically relevant animal model for studying inflammation.
• To assess differences in inflammatory responses between infected and uninfected mice.

Methods Used

• Oral infection of mice with Porphyromonas gingivalis.
• Utilization of MRI to measure systemic inflammation.
• Micro CT for assessing local inflammatory bone loss.
• On face lipid staining for visualizing atherosclerotic plaques.

Main Results

• Differences in alveolar bone volume were observed between infected and control mice.
• Accumulation of atherosclerotic plaques was visualized in infected mice.
• Both local and systemic inflammatory responses were effectively measured.
• The model allows for the examination of host and pathogen mechanisms.

Conclusions

• This mouse model is valuable for studying chronic inflammation.
• It provides insights into the mechanisms of infection and inflammation.
• The methodologies can be applied to other pathogens and conditions.
