Functional Analysis of Foxp3 and Its Mutants by Retroviral Transduction of Murine Primary CD4+ T Cells

Methods Mol Biol. 2023:2559:79-94. doi: 10.1007/978-1-0716-2647-4_7.

Abstract

The transcription factor Foxp3/FOXP3 orchestrates regulatory T (Treg) cell development and function by interacting with numerous target genes and partner proteins. Functional analysis of naturally occurring or engineered Foxp3/FOXP3 mutations has provided important insights into how the complex Foxp3/FOXP3-centered molecular network operates. Here, we describe detailed protocols for retroviral transduction of murine primary conventional CD4+ T cells to determine the impacts of Foxp3 mutations on the Treg-cell-like phenotype and function conferred by Foxp3.

Keywords: Flow cytometry; Foxp3, mutagenesis; Regulatory T cells; Retroviral gene transduction.
