Insights

Cardiovascular diseases involve inflammation, often triggered by the cyclic GMP-AMP synthase/stimulator of IFN genes (cGAS/STING) pathway. Targeting this pathway shows therapeutic potential for treating cardiovascular diseases.

Area of Science:

  • Cardiovascular research
  • Immunology
  • Molecular biology

Background:

  • Cardiovascular diseases (CVDs) are a leading global cause of death.
  • Inflammation is a critical factor in CVD development.
  • The cyclic GMP-AMP synthase/stimulator of IFN genes (cGAS/STING) pathway is implicated in inflammatory processes.

Purpose of the Study:

  • To review the role of self-DNA and the cGAS/STING pathway in CVD pathophysiology.
  • To explore the therapeutic potential of targeting the cGAS/STING pathway for CVD treatment.

Main Methods:

  • Literature review and synthesis of current research on the cGAS/STING pathway in cardiovascular contexts.
  • Analysis of the mechanisms by which self-DNA activates inflammatory signaling in CVD.

Main Results:

  • The cGAS/STING pathway recognizes self-DNA, activating downstream inflammatory signaling (TBK1, IRF3, NF-κB).
  • Circulating cell-free DNA serves as a biomarker for CVDs.
  • The precise contribution of self-DNA to CVD-related inflammation, cell death, and fibrosis requires further elucidation.

Conclusions:

  • The cGAS/STING pathway plays a significant role in the inflammatory basis of cardiovascular diseases.
  • Targeting the cGAS/STING pathway presents a promising therapeutic strategy for managing CVDs.

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.

Regulation of the Cardiovascular System

The regulation of the cardiovascular system allows the body to adapt to various demands and maintain homeostasis.
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
Intracellular Signaling Cascades01:24

Intracellular Signaling Cascades

Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

G-Protein Gated Ion Channels

GPCRs are primarily responsible for our sense of smell, taste, and vision.  The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
