NLRP3-like protein negatively regulates the expression of antimicrobial peptides in Penaeus vannamei hemocyates.

ABSTRACT: NACHT, LRR and PYD domains-containing protein 3 (NLRP3) protein is the core actor involved in inflammasome formation, and plays a pivotal role in the innate immune response. However, whether NLRP3 participates in the regulation of innate immunity in invertebrates is still unknown. In the present study, we characterized a NLRP3 ortholog in Penaeus vannamei (designated PvNLRP3-like) with 2514 bp length of open reading frame (ORF) encoding a putative protein of 837 amino acids. Sequence analysis revealed that PvNLRP3-like contained only NACHT domain and shared closely homology with other invertebrates, but the topological structure of NACHT domain of PvNLRP3-like is similar with that in human NLRP3. PvNLRP3-like was ubiquitously expressed in tissues and induced in hemocytes by Vibri
