Abstract:
... In this study, RNA-seq gene expression data were obtained for three different immune tissues (bone marrow, thymus, and bursa) at two time points from birds with three phenotypes (non-infected, resistant, and susceptible birds). A total of 380 significant differentially expressed genes (DEGs) were commonly expressed in each of the three tissues in the contrast of susceptible vs. non-infected birds ...
