简介：
Overview
This article presents a protocol for differentiating murine granulocyte-macrophage-colony-stimulating-factor-producing T helper (T H GM) cells from naive CD4+ T cells. The method includes the isolation of naive CD4+ T cells, their differentiation into T H GM cells, and subsequent analysis of these differentiated cells.
Key Study Components

- To investigate the role of T H GM cells in inflammatory diseases.
- To enhance the understanding of T-cell subsets in immune responses.
Methods Used
- Isolation of naive CD4+ T cells from mouse spleens.
- Differentiation of naive CD4+ T cells into T H GM cells.
- Analysis of differentiated T H GM cells for GM-CSF expression.
- Use of sterile techniques to ensure sample integrity.
Main Results
- The protocol successfully generates over 50% GM-CSF expressing T-cells.
- Minimal interference from other T-cell subsets was observed.
- This method provides a valuable cellular source for studying T H GM cell function.
