Except for SLC26A6 and NUMB, all other genes showed expression patterns similar to those observed in our study: higher in LS than PS at day 0 and up-regulated in both LS and PS at day 2 p.i. In addition, the genes SLC11A1, TLR4 and CD14, which are known to play important roles during Salmonella infection, showed similar expression patterns as described above. This evidence concerns the gene NUMB and Salmonella Infections.
