As shown in Table 6, most of the up-regulated genes between 0 and 8 h post infection such as protein tyrosine phosphatase epsilon (ptpε), integrin alpha 7 (itga7) and periplakin (ppl), are associated with cell signaling, whereas down-regulated genes such as C–X–C motif chemokine 10-like (cxcl10) and interferon alpha-inducible protein 27-like (ifi27l) are associated with immunity. The gene discussed is PPL; the disease is infection.
