Assembly and Architecture of NLR Resistosomes and Inflammasomes

Abstract

Nucleotide-binding and leucine-rich repeat (NLR) proteins are critical intracellular immune receptors in both animals and plants. Perception of pathogen-derived or stress-associated signals induces NLR oligomerization to form multiprotein complexes called inflammasomes in animals or resistosomes in plants to mediate host immune response. Significant progress has been made during the past few years in our understanding of NLR biology, particularly the structural perspective of these two types of NLR-containing complexes. In this article, we review the latest advances in our structural knowledge of how NLR inflammasomes and resistosomes are activated and assembled and how the structural information provides insight into their distinct mechanisms of action. Commonalities and differences between NLR inflammasomes and resistosomes are also discussed.
