Whilst WC1+ γδ T cells were significantly lower compared to the uninfected (negative control) sheep at 6 dpi for the CD4+ T cell-depleted sheep (p = 0.049) and 8 dpi for the mock-depleted sheep (p = 0.018), the biological relevance of these single data point differences is uncertain given the inherent variation between sheep during the infection time course. Here, CD4 is linked to infection.
