IFNA1 and infection: Figure 11 shows infection outcome for the four cases assuming a pulsed secretion model with q0=0.01 and q1=1. Strong antagonism blocks the IFN response, with IFN levels only reaching roughly 50 U/mL for the highest infectivity of p=0.5, leading to complete loss of protection. Intermediate antagonism leads to significant maximal IFN concentrations, but the response does not mediate significant protection. For weak and no antagonism, once p>0.1, extracellular IFN levels are nearly maximal, reflecting full activation of the feedback loop, leading to significant levels of protection.
