The epigenome of macrophages can be reprogrammed by extracellular cues, but the extent to which different stimuli achieve this is unclear. NFκB is a transcription factor that is activated by all pathogen-associated stimuli and can reprogram the epigenome by activating latent enhancers. However, we show that NFκB does so only in response to a subset of stimuli. This stimulus-specificity depends on the temporal dynamics of NFκB activity, in particular whether it is oscillatory or non-oscillatory. Non-oscillatory NFκB opens chromatin by sustained disruption of nucleosomal histone-DNA interactions, enabling activation of latent enhancers that modulate expression of immune response genes. Thus, temporal dynamics can determine a transcription factor’s capacity to reprogram the epigenome in a stimulus-specific manner. Nucleosomal DNA interactions decode NFκB dynamics to regulate activation of latent enhancers of immune response genes.
