RELA and infection: A large number of genes (45) over-expressed in DCs have previously been reported to be induced in nutrient limitation conditions (e.g. pdhA/B, cysD, ald, lat, and rocA/D1) [48], in addition relA, which encodes the putative regulator of the stringent response that is induced under starvation, was also over-expressed during DC compared to Mφ infection.
