Abstract

The placenta is an immunological paradox since maternal immune cells infiltrating placental tissues need to be tolerant toward the fetus but still retain immunity against potential infections. This makes the placenta an interesting tissue for studying immunological processes. Mucosal-associated invariant T (MAIT) cells are a subset of T cells that respond to bacterially derived metabolites of riboflavin synthesis. Upon activation, MAIT cells respond by secretion of inflammatory cytokines and by directed killing of infected cells by the use of granzymes and perforin. In this protocol, we describe methods for the isolation of immune cells from the placental intervillous space and adjacent tissues such as the umbilical cord, decidua parietalis, and decidua basalis. We further describe how to stimulate MAIT cells in mixed cell suspensions of mononuclear cells with bacteria, and how to analyze the phenotypic and functional responses with flow cytometry.
