Адоптивный перенос IL-33-стимулированных макрофагов в блеомицин-индуцированные мышиные модели для изучения их влияния на идиопатический легочный фиброз in vivo

Overview

This protocol describes the isolation of pulmonary interstitial macrophages (IMs) and their adoptive transfer after IL-33 stimulation in a mouse model. This technique facilitates the in vivo study of idiopathic pulmonary fibrosis (IPF).

Key Study Components

Area of Science

• Neuroscience
• Immunology
• Pulmonary Biology

Background

• Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease.
• Macrophages play a crucial role in lung inflammation and fibrosis.
• IL-33 is a cytokine involved in immune responses in the lung.
• Understanding macrophage function can provide insights into IPF mechanisms.

Purpose of Study

• To isolate pulmonary interstitial macrophages (IMs) from mouse lungs.
• To investigate the effects of IL-33 on macrophage behavior.
• To facilitate in vivo studies of IPF using a mouse model.

Methods Used

• Isolation of pulmonary interstitial macrophages (IMs).
• Adoptive transfer of IMs after IL-33 stimulation.
• Administration of clodronate liposomes to deplete macrophages.
• Use of anesthetized mice for nasal administration of treatments.

Main Results

• Successful isolation of IMs from mouse lungs.
• Demonstrated effects of IL-33 on macrophage function.
• Provided a method for studying IPF in vivo.
• Highlighted the role of macrophages in lung pathology.

Conclusions

• The protocol allows for the study of macrophage dynamics in IPF.
• IL-33 stimulation can enhance understanding of macrophage roles.
• This method can be applied to further research in pulmonary diseases.
