Web16 Nov 2015 · Nuclear factor κB (NF-κB) is a family of inducible transcription factors that plays a vital role in different aspects of immune responses. NF-κB is normally sequestered in the cytoplasm as inactive complexes via physical association with inhibitory proteins termed IκBs. In response to immune and stress stimuli, NF-κB members become activated via … WebB cells further reinforce the Tfh transcriptional program and drive the final steps of differentiation through ICOS-ICOSL and CD40− CD40L interactions (Baumjohann et al., 2013). ...
