고급 폐 유도 빛 시트 현미경 검사 법에 따라 알레르기 염증의 Vivo 모델에서 실험에서 인간 림프 톨의 이미징

Overview

This protocol enables the imaging and quantification of lung-homing human immune cells in a mouse model of allergic inflammation. It provides insights into T cell lung homing under in vivo inflammatory conditions.

Key Study Components

Area of Science

• Immunology
• Inflammatory Diseases
• Translational Research

Background

• Understanding T cell lung homing is crucial for developing therapies for pulmonary diseases.
• Activated immune cells accumulate in lung tissue during chronic inflammation.
• Current methods lack precision in imaging these processes.
• This protocol addresses these gaps by utilizing light-sheet fluorescence microscopy.

Purpose of Study

• To characterize the lung homing capacity of primary human lymphocytes.
• To provide a method for imaging immune cell infiltration in lung tissue.
• To support research in identifying new therapeutic targets for allergic and inflammatory lung diseases.

Methods Used

• Use of a micropipet to deliver papain solution into the nostril of anesthetized mice.
• Density gradient separation of human peripheral blood using Ficoll medium.
• Light-sheet fluorescence microscopy for imaging cleared lung tissue.
• Quantification of immune cell accumulation in the lungs.

Main Results

• Successful imaging of human immune cells in the lungs of mice.
• Demonstrated the influence of inflammatory conditions on T cell homing.
• Provided a reliable method for studying immune cell behavior in vivo.
• Highlighted the potential for identifying new therapeutic targets.

Conclusions

• This technique is valuable for immunological research in chronic lung diseases.
• It allows for a better understanding of T cell dynamics in inflammatory environments.
• The protocol can aid in the development of optimized therapies for pulmonary conditions.
