Summary
The NLRP3 inflammasome links inflammation, oxidative stress, and metabolic dysfunction in type 2 diabetes (T2DM) and gout. It acts as a sensor for metabolic stress, driving disease pathogenesis.
Area of Science:
- Immunology
- Metabolic Diseases
- Molecular Biology
Background:
- Interleukin-1beta (IL-1beta), reactive oxygen species (ROS), and thioredoxin-interacting protein (TXNIP) are key factors in type 2 diabetes mellitus (T2DM) pathogenesis.
- Chronic hyperglycemia contributes to islet dysfunction, a hallmark of T2DM.
Purpose of the Study:
- To review mechanisms of IL-1beta production and its role in T2DM islet dysfunction.
- To integrate disparate mechanisms of IL-1beta, ROS, and TXNIP in T2DM pathogenesis.
- To propose a unifying model where the NLRP3 inflammasome is central.
Main Methods:
- Literature review of mechanisms linking IL-1beta, ROS, TXNIP, and T2DM.
- Integration of existing data into a cohesive model of disease pathogenesis.
- Comparison of NLRP3 inflammasome roles in T2DM and gout.
Main Results:
- IL-1beta, ROS, and TXNIP are implicated in T2DM pathogenesis.
- The NLRP3 inflammasome plays a central role in integrating these factors.
- NLRP3 inflammasome activation drives IL-1beta maturation and secretion.
Conclusions:
- The NLRP3 inflammasome serves as a unifying mechanism in T2DM pathogenesis.
- The NLRP3 inflammasome is also involved in the pathogenesis of gout, another metabolic disease.
- NLRP3 inflammasome acts as a metabolic stress sensor in T2DM and gout.

01:31Regulation 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...
02:26NF-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.

01:37The Unfolded Protein Response
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
01:17The 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...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
