Abstract
Specific antigen recognition by T cell receptor (TCR) activates TCR signaling pathway, leading to T cell proliferation and differentiation into effector and memory cells. Herein, we describe protocols for TCR stimulation assays, including procedures for the isolation and enrichment of mouse splenic T cells for ex vivo TCR stimulation with anti-CD3/CD28 antibodies, and the use of ovalbumin-OT-II mouse model for in vivo TCR stimulation. We applied this protocol to show that MYC protein is essential for T cell proliferation and differentiation. For complete details on the use and execution of this protocol, please refer to Nozais et al. (2021).
