Abstract

Innate lymphoid cells (ILCs) are important for both tissue immunity and tissue homeostasis. They are classified into three groups: Group 1 ILCs include NK cells, which are important in eliciting immunity against intracellular pathogens; group 2 ILCs protect against parasitic helminths; and group 3 ILCs protect against extracellular pathogens. The role of ILCs in cancer immunity remains unclear. In this chapter, we discuss methods for isolating and characterizing tumor-infiltrating ILC subsets within the tumor microenvironment in an experimental murine model of B16 melanoma. The chapter also highlights the expression of PD-1 on the various ILC subsets within the tumor microenvironment.
