IKKα contributes to canonical NF-κB activation downstream of Nod1-mediated peptidoglycan recognition.

ABSTRACT:

Background

During pathogen infection, innate immunity is initiated via the recognition of microbial products by pattern recognition receptors and the subsequent activation of transcription factors that upregulate proinflammatory genes. By controlling the expression of cytokines, chemokines, anti-bacterial peptides and adhesion molecules, the transcription factor nuclear factor-kappa B (NF-κB) has a central function in this process. In a typical model of NF-κB activation, the recognition of pathogen associated molecules triggers the canonical NF-κB pathway that depends on the phosphorylation of Inhibitor of NF-κB (IκB) by the catalytic subunit IκB kinase β (IKKβ), its degradation and the nuclear translocation of NF-κB dimers.

Methodology

Here, we performed an RNA interference
