Insights

Regular moderate exercise suppresses NLRP3 inflammasome activation, a key driver of non-communicable diseases. Exercise-released factors offer multi-nodal suppression unmatched by single drugs.

Area of Science:

  • Exercise Science
  • Immunology
  • Molecular Biology

Background:

  • Chronic low-grade inflammation via NLRP3 inflammasome activation is central to non-communicable diseases (NCDs).
  • Current single-target drugs for NLRP3 inhibition show limited efficacy and durability.
  • Exercise offers broad, multi-system protection through diverse signaling molecules called exerkines.

Purpose of the Study:

  • To review evidence on how exercise-derived factors modulate the NLRP3 inflammasome.
  • To explore the multi-nodal suppression mechanisms of chronic moderate-intensity exercise on NLRP3.
  • To propose a precision exercise medicine framework for managing NLRP3-driven metaflammation.

Main Methods:

  • Narrative review of preclinical and human studies.
  • Synthesis of evidence on exercise-released myokines, hepatokines, adipokines, metabolites, microbiota factors, and extracellular vesicle RNAs.
  • Analysis of molecular and cellular mechanisms of NLRP3 inflammasome regulation by exercise.

Main Results:

  • Exercise-released factors (e.g., irisin, FGF21, lactate, SCFAs, non-coding RNAs) target multiple NLRP3 inflammasome nodes.
  • Chronic moderate-intensity exercise (150-300 min/wk) induces profound NLRP3 suppression.
  • Mechanisms include NF-κB attenuation, mitochondrial protection, direct NLRP3/ASC interference, and enhanced autophagy.

Conclusions:

  • Exercise-induced multi-nodal NLRP3 suppression offers a systems-level approach superior to single-target pharmacology.
  • A precision exercise medicine framework integrating exerkine, genetic, and microbiome data can personalize interventions.
  • Future strategies may combine exercise mimetics, RNA therapeutics, and synergistic pharmacology for NLRP3-driven metaflammation.

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
