The first five of these genes (GZMB, LYZ, XDH and GBP4) have comparable expression profiles for N'Dama and Boran and therefore have no significant breed differences after infection; the last three (CTSS, NCR3 and BAFF), on the other hand, have diverging profiles and significant differences between N'Dama and Boran at either 14 or 21 dpi. The gene discussed is TNFSF13B; the disease is infection.
