Abstract

Type 1 regulatory T (Tr1) cells are an immunoregulatory CD4+ Foxp3- IL-10high T cell subset with therapeutic potential for various inflammatory diseases. Retroviral (RV) transduction has been a valuable tool in defining the signaling pathways and transcription factors that regulate Tr1 differentiation and suppressive function. This protocol describes a method for RV transduction of naïve CD4+ T cells differentiating under Tr1 conditions, without the use of reagents such as polybrene or RetroNectin. A major advantage of this protocol over others is that it allows for the role of genes of interest on both differentiation and function of Tr1 cells to be interrogated. This is due to the high efficiency of RV transduction combined with the use of an IL10GFP/Foxp3RFP dual reporter mouse model, which enables successfully transduced Tr1 cells to be identified and sorted for functional assays. In addition, this protocol may be utilized for dual/multiple transduction approaches and transduction of other lymphocyte populations, such as CD8+ T cells.

Background

Type 1 regulatory T (Tr1) cells are an immunoregulatory Foxp3- CD4+ T cell subset that is able regulate inflammation and induce tolerance, making them a promising candidate for immunotherapies (Mobs et al., 2010; Gol-Ara et al., 2012; Roncarolo et al., 2014; Bohm et al., 2015). Therefore, signaling pathways and transcription factors regulating Tr1 differentiation and suppressive function are of great clinical interest. RV transduction of CD4+ T cells has been an effective tool in this endeavor (Wu et al., 2013; Mascanfroni et al., 2015; Karwacz et al., 2017). Many studies use Tr1 differentiation as an endpoint because detection of IL-10 and Foxp3 require terminal methods, such as fixation of cells. As a result, signaling pathways and transcription factors regulating the suppressive function of Tr1 cells are less understood than those required for differentiation. This protocol was developed to investigate the role of signaling pathways and transcription factors downstream of TCR/ITK, which regulate both Tr1 differentiation and suppressive function (Huang et al., 2017). The use of an IL10GFP/Foxp3RFP dual reporter mouse model, high efficiency of RV transduction, and bicistronic retroviral vectors that enable transduced cells to be identified via expression of a reporter gene allows sufficient numbers of live transduced Tr1 cells to be isolated for functional assays. Another advantage of this protocol is that it does not make use of chemical transduction enhancers, such as RetroNectin or polybrene, which may be cost-prohibitive and cause cytotoxicity (Kurachi et al., 2017; Eremenko et al., 2021). In addition, the protocol described here may also be utilized for dual transduction strategies and other lymphocyte populations, such as CD8+ T cells.
