简介：
Overview
This article presents a novel protocol for isolating highly purified double negative T (DN T) cells from murine kidney. Despite their rarity among peripheral T cells, DN T cells are abundant in certain non-lymphoid tissues, making their study crucial for understanding their pathophysiologic significance.
Key Study Components
Area of Science
- Immunology
- Cell Biology
- Neuroscience
Background
- DN T cells are significant in various immune responses.
- Isolation from non-lymphoid tissues has been challenging.
- Previous studies indicated immune cells mediate acute kidney injury.
