Gut mucosal immune cells play an essential role in health due to their ability to orchestrate host signaling events in response to exogenous antigens. These antigens may originate from microorganisms including viruses, commensal or pathogenic bacteria, or single-celled eukaryotes, as well as from dietary foodstuff-derived proteins or products. A critical technological capacity to understand host responses to antigens is the ability to efficiently isolate and functionally characterize immune cells from intestinal tissues. Additionally, after characterization, it is of paramount importance to understand the exact functions of these immune cells under different disease states or genetic variables. Here, we outline methods for immune cell isolation from murine small and large intestines with the goal of undertaking a functional analysis of isolated cell types using antibody array platforms.
