Acute Inflammation II: Local and Systemic Effects01:25

Acute Inflammation II: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
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...
Vascular Resistance01:20

Vascular Resistance

Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...
Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:
Activation and Inactivation of G Proteins01:22

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...

Area of Science:

  • Biochemistry
  • Pharmacology
  • Immunology

Background:

  • G-protein coupled receptor 109A (GPR109A) is the receptor for niacin and 3-hydroxy-butyrate.
  • Niacin is used to treat cardiovascular disease due to its effects on lipoproteins.
  • Niacin also has lipoprotein-independent effects influencing inflammatory pathways via GPR109A.

Purpose of the Study:

  • To explore the role of GPR109A in atherosclerosis and vascular inflammation.
  • To investigate niacin's pleiotropic mechanisms of action.
  • To provide insights for future GPR109A-targeted drug development.

Main Methods:

  • Review of existing literature on GPR109A signaling.
  • Analysis of niacin's effects on lipoprotein metabolism and inflammation.
  • Examination of GPR109A's role in cardiovascular disease models.

Main Results:

  • GPR109A mediates both G-protein dependent and β-arrestin dependent signaling.
  • Niacin's effects extend beyond lipoprotein modification to influence inflammatory pathways.
  • GPR109A plays a significant role in the pathogenesis of atherosclerosis.

Conclusions:

  • GPR109A is a critical mediator of niacin's cardiovascular and anti-inflammatory effects.
  • Understanding GPR109A signaling is crucial for developing novel therapeutics for atherosclerosis.
  • Targeting GPR109A pathways offers potential for managing metabolic and inflammatory diseases.
