The regulation pattern of cd8α transcripts was comparable in both infection groups: ≈1 fold change (fc) at 10 dpe, before increasing at 50 dpe (YOY (p < 0.001) juvenile 1+ (p < 0.01) and slightly declining at 80 dpe in both YOY (p < 0.001) and juvenile 1+ infected fish (p = 0.02), with significant upregulations in comparison to their respective controls at these latter time points in both infection groups (Figure 10B). The gene discussed is CD8A; the disease is infection.
