Overall, whilst a pathogenic role is clear for BATF2 in the context of Type-1 infectious diseases and warrants further assessment of the therapeutic value of inhibiting this factor, Type-2 and Type-17 controlled infectious diseases appears to require BATF2 to tame untoward immune responsiveness and as such might be aggravated by the Batf2 blockade. Here, BATF2 is linked to infectious disease.
