Nonclassical T cells are a heterogeneous group of T lymphocytes that are activated during the early stages of infection and act as a bridge between the innate and adaptive immune system. Among them, Natural Killer T (NKT) cells have been extensively studied in the last two decades due to their unique ability to recognize foreign/self-lipid antigens in the context of CD1d, a nonclassical major histocompatibility complex molecule. In this chapter, we describe our protocols to track murine NKT cells in lymph nodes by flow cytometry and confocal microscopy.
