Abstract

The identification of several families of innate pattern recognition receptors has greatly enhanced our understanding of the host innate immune response against a variety of pathogens. One such family of innate receptors is the nucleotide-binding domain and leucine rich repeat containing receptors (NLRs). NOD2 has been characterized as a cytosolic sensor of bacteria peptidoglycan (PGN). For almost 10 years, NOD2 was assigned with the function of mediating the RICK- and nuclear factor-κB induced proinflammatory response triggered by PGN. Recent studies have extended the biological activity of NOD2 to include the induction of autophagy and antiviral responses, as well as mediating direct T cell activation. Here, we highlight and discuss these new findings in the context of immune activation and pathogen detection.
