Phenotypic and Functional Studies of Human Treg Cell Subpopulations.

CD4 ⁺ regulatory T (Treg) cells play an important role in maintaining immune homeostasis. Although these cells were initially studied as a homogenous cohort, we now know that they have unprecedented underlying heterogeneity. This heterogeneity is reflected in their phenotype and functions. As human Treg subpopulations are very small in numbers, it is necessary to develop novel ways of isolating and manipulating these cell populations. In this chapter, we discuss immunoassays established to this effect.
