CD8A and infection: Since type I cDCs are reported to cross‐present viral antigens to CD8+ T cells19 we also assessed relationships between these two cell types during these RV infections and observed positive correlations between these cell populations in BAL at both D3 (p = .015, r = .502) and D8 post‐infection (p = .001, r = .642) (Figure 5A,B).
