Expression of gamma/delta T cell receptors on lymphocytes from the lactating mammary gland.

Abstract
Gamma/delta cells were at least four times more frequent in lactating mouse mammary glands than among T cells of the most proximal lymph nodes. Two-color staining of freshly isolated T cells and a study of clonally expressed gamma/delta receptors on hybridomas further revealed that the mammary gamma/delta population is heterogeneous, including at least three different subsets, among them cells expressing V gamma 5, V gamma 4 together with V delta 4, or none of these V regions.
