Abstract

Insights

Apigenin, a natural compound, effectively inhibits inflammasome activation by reducing the maturation of caspase-1. This study demonstrates apigenin

Area of Science:

  • Immunology
  • Molecular Biology
  • Pharmacology

Background:

  • The inflammasome is a key regulator of inflammatory responses.
  • Dysregulation of inflammasome activation is implicated in various diseases.
  • Apigenin is a natural flavonoid with potential anti-inflammatory properties.

Purpose of the Study:

  • To investigate the effect of apigenin on inflammasome activation.
  • To elucidate the underlying molecular mechanisms of apigenin's action.

Main Methods:

  • THP-1 cells were treated with lipopolysaccharides (LPS) and varying concentrations of apigenin.
  • Interleukin (IL)-1β secretion was measured using ELISA.
  • Western blot was employed to assess the cleavage of pro-IL-1β and pro-caspase-1.
  • Reporter gene assay was used to detect nuclear factor (NF)-κB activation.

Main Results:

  • Apigenin exhibited low cytotoxicity in THP-1 cells.
  • Apigenin significantly inhibited LPS-induced IL-1β secretion.
  • Apigenin suppressed the maturation of pro-IL-1β and pro-caspase-1.
  • Apigenin attenuated LPS-induced NF-κB activation.

Conclusions:

  • Apigenin inhibits LPS-induced inflammasome activation.
  • The mechanism involves the inhibition of caspase-1 maturation.
  • Apigenin demonstrates potential as a therapeutic agent for inflammatory conditions.

Formation of Lipopolysaccharides01:19

Formation of Lipopolysaccharides

Lipopolysaccharides (LPS) are crucial components of the outer membrane of Gram-negative bacteria, serving both structural and functional roles. It contributes to membrane stability and protects bacteria from host immune responses. LPS is composed of three major regions—lipid A, a core oligosaccharide, and an O antigen. The biosynthesis and assembly of LPS involve a highly coordinated set of enzymatic reactions and transport mechanisms. Additionally, LPS is recognized as an endotoxin, triggering...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
The Intrinsic Apoptotic Pathway01:31

The 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...
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...
GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of cells.
