遺伝子研究の概要
NLRP3, also known as NACHT, leucine-rich repeat (LRR), and pyrin domain (PYD)-containing protein 3, is a crucial component of the NLRP3 inflammasome. The NLRP3 inflammasome is a multi-protein signaling complex that triggers the activation of inflammatory caspases and the maturation of interleukin-1β. It plays a significant role in the inflammatory response, being activated by various host “danger” situations like infection and metabolic dysregulation [1,2].
Mitophagy/autophagy blockade leads to the accumulation of damaged mitochondria that generate reactive oxygen species (ROS), which in turn activates the NLRP3 inflammasome [1]. Different NLRP3 stimuli cause the disassembly of the trans-Golgi network (TGN), and NLRP3 is recruited to the dispersed TGN through an ionic bond with phosphatidylinositol-4-phosphate (PtdIns4P), leading to its aggregation and downstream signaling activation [3]. Palmitoylation of NLRP3 Cys126 by ZDHHC7 promotes NLRP3-mediated inflammasome activation both in macrophages and in vivo [4].
The NLRP3 inflammasome is involved in various disease conditions. For example, in inflammatory root resorption, force-pre-treated human periodontal ligament cells (hPDLCs) promote M1 macrophage polarization and the production of NLRP3, caspase-1, and IL-1β in M1 macrophages, and this can be inhibited by an NLRP3 inflammasome inhibitor [5]. In acute liver injury, the aberrant activation of the NLRP3 inflammasome plays an important role, and it is closely related to programmed cell death [6]. Also, NLRP3 activation is associated with many cardiovascular diseases and is a potential target for treatment [7]. In COVID-19, NLRP3 activation may contribute to the intense and rapid stimulation of the innate immune response [8].
In conclusion, NLRP3 is essential for the activation of the NLRP3 inflammasome and subsequent inflammatory responses. Through model-based research, especially in conditions like liver injury, inflammatory root resorption, cardiovascular diseases, and COVID-19, the role of NLRP3 in disease-associated inflammation has been revealed. Understanding NLRP3 function provides potential therapeutic strategies for these diseases.
