An Intracellular Pathogen Response Pathway Promotes Proteostasis in C. elegans.

ABSTRACT: Maintenance of protein homeostasis, or proteostasis, is crucial for organismal health. Disruption of proteostasis can lead to the accumulation of protein aggregates, which are associated with aging and many human diseases such as Alzheimer's disease [1-3]. Through analysis of the C. elegans host response to intracellular infection, we describe here a novel response pathway that enhances proteostasis capacity and appears to act in parallel to well-studied proteostasis pathways. These findings are based on analysis of the transcriptional response to infection by the intracellular pathogen Nematocida parisii [4]. The response to N. parisii is strikingly similar to the response to infection by the Orsay virus, another natural intracellular pathogen of C. elegans, and is distinct from responses
