IL17A and influenza: Given the anticipated role of IL-17 in rescuing Type 17 immunity and potentially overcoming the limitations of recombinant protein administration, such as poor delivery system, rapid clearance, and short half-life, we turned to an adenoviral vector expressing IL-17 in the influenza and A. fumigatus-superinfected mice, proposing that it would rescue Type-17 immunity and enhance fungal clearance (Figure 3A).
