| Summary |
Developmental signals are known to modulate inflammation. How ever, the mechanistic insight that links developmental and inflammatory signaling remains elusive. In the current study, we identifya critical role of NF-kB system in mediating stimulus specific crosstalk that allows developmental LTbR signals to sustain inflammatory TLR4 induced RelA/NF-kB response and gene expression. LTbR activated non-canonical signaling targets canonical TLR4 induced, nfkb2 encoded p100 not only to deplete inhibitory IkBd/(p100)2, but also to supplement RelA:p52/NF-kB dimers. Robust crosstalk in the gut epithelial cells are important, as crosstalk-defective nfkb2-/- mice succumbed to gut infection by Citrobacter rodentium due to hypo-inflammatory responses. Finally, we present evidence for a crosstalk motif that integrates tissue microenvironment derived developmental cues to ameliorate the pathogen response.
