TLDR
The results link bacterial sensing by Nod proteins to the induction of autophagy and provide a functional link between Nod2 and ATG16L1, which are encoded by two of the most important genes associated with Crohn's disease.Abstract:
Autophagy is emerging as a crucial defense mechanism against bacteria, but the host intracellular sensors responsible for inducing autophagy in response to bacterial infection remain unknown. Here we demonstrated that the intracellular sensors Nod1 and Nod2 are critical for the autophagic response to invasive bacteria. By a mechanism independent of the adaptor RIP2 and transcription factor NF-kappaB, Nod1 and Nod2 recruited the autophagy protein ATG16L1 to the plasma membrane at the bacterial entry site. In cells homozygous for the Crohn's disease-associated NOD2 frameshift mutation, mutant Nod2 failed to recruit ATG16L1 to the plasma membrane and wrapping of invading bacteria by autophagosomes was impaired. Our results link bacterial sensing by Nod proteins to the induction of autophagy and provide a functional link between Nod2 and ATG16L1, which are encoded by two of the most important genes associated with Crohn's disease.read more

TL;DR: It is reported that efficient cytosolic immune sensing requires access of nucleic acids derived from live Listeria to the cytoplasm of infected cells and RIG‐I provides a mechanistic explanation for efficient induction of immunity by live bacteria.

Autophagy – an emerging immunological paradigm
TL;DR: Genome-wide association studies in human populations strongly implicate autophagy in chronic inflammatory disease and autoimmune disorders and its contributions to other arms of the immune system represent a new immunological paradigm.

NLRP4 Negatively Regulates Autophagic Processes through an Association with Beclin1
TL;DR: Novel evidence is provided that NLRP4, and possibly other members of the NLR family, plays a crucial role in biogenesis of the autophagosome and its maturation by the association with regulatory molecules, such as Beclin1 and the class C vacuolar protein-sorting complex.

TL;DR: It is suggested that the NOD2 gene product confers susceptibility to Crohn's disease by altering the recognition of these components and/or by over-activating NF-kB in monocytes, thus documenting a molecular model for the pathogenic mechanism of Crohn’s disease that can now be further investigated.

TL;DR: The results suggest that the continuous clearance of diffuse cytosolic proteins through basal autophagy is important for preventing the accumulation of abnormal proteins, which can disrupt neural function and ultimately lead to neurodegeneration.
