Conventional dendritic cells (cDC) are professional antigen-presenting cells able to prime naive T cells. Here, we present a protocol for ex vivo T cell priming by murine splenic cDC. We describe the steps of injecting fluorescently labeled antigens to mice, purifying antigen-bearing cDC, and priming antigen-specific T cells ex vivo. This protocol is suitable for studying the T cell priming function of cDC in various murine models and helps factor in the effect of the microenvironment on cDC ability to uptake and process antigens. For complete details on the use and execution of this protocol, please refer to Ashayeripanah et al.1.
