Analysis of gene expression in different T cell clones

ABSTRACT: The aim was to analyze the expression of genes in T cell clones having different functional profiles (Th1, Th0, Th17, Th2) obtained from the same individual. Keywords: Gene expression, T cell clones, Th17 characterisation The T cell clones were derived according to well known protocol, using different cytokines, and classified on the basis of their ability to produce cytokines. Once characterized for their production of IL-4, IL-12, gamma-IFN, IL-13, IL-1, they were used to prepare microarray experiments.

We demonstrate that CD161 is a highly up-regulated gene in human interleukin (IL) 17 T helper cell (Th17) clones and that all IL-17-producing cells are contained in the CD161(+) fraction of CD4(+) T cells present in the circulation or in inflamed tissues, although they are not CD1-restricted natural killer T cells. More importantly, we show that all IL-17-producing cells originate from CD161(+) naive CD4(+) T cells of umbilical cord blood, as well as of the postnatal thymus, in response to the c  ...[more]
