T-bet-Eomes [ChIP-Seq]
This project aims at understanding the role of T-bet and Eomes in the differentiation of Natural Killer (NK) cells. NK cells are innate cytotoxic lymphocytes that play an important role in the early control of viral infections and in immune surveillance of cancers. T-bet and Eomes are related T-box factors that are co-expressed by NK cells and are supposed to bind to similar DNA motifs. Their role in NK cell differentiation are not very well understood, in part because their direct target genes are unknown. This study is designed to identify T-bet and Eomes target genes in NK cells. It is based on two complementary mouse strains that we generated in the lab that express tagged (HA) forms of T-bet or Eomes. The tag sequences were inserted in the C-terminus region of both factors, by homomogous recombination in ES cells, allowing endogenous regulation of T-bet and Eomes. Overall design: Two Chip replicates were performed for each genotype (Eomes-HAV5,  T-bet-HAV5, and control ie C57BL/6). Fpr each Chip 10 millions spleen NK  cells were used as starting material and the Chip was performed using  anti-HA antibody.
