T cells are able to recognize and kill pathogens that infect host cells, including bacteria, viruses, and tumor cells. Here, we present a protocol to detect T cell function and bacterial load in OVA-Listeria monocytogenes-infected mice. We provide a detailed description of the steps for detecting OVA-specific CD8+ T cells and their cytokine expression levels in splenocytes using flow cytometry on day 7 after infecting mice with OVA-Listeria monocytogenes. Additionally, we describe the steps for detecting the OVA-Listeria monocytogenes load in the mouse liver. For complete details on the use and execution of this protocol, please refer to Chen et al.1.
