Inflammatory Response

17.9K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Atherosclerosis I: Introduction

1.7K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Atherosclerosis III: Management

541
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Coronary Artery Disease II: Pathophysiology

857
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Inflammatory Response I: Vascular and Cellular

17.7K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Summary
This summary is machine-generated.

Specialized proresolving lipid mediators (SPMs) help resolve inflammation. Imbalances in SPMs are linked to atherosclerosis, but restoring SPM levels can stabilize plaques and offer therapeutic potential.

Area of Science:

  • Cardiovascular Research
  • Inflammation Biology
  • Lipid Mediator Science

Background:

  • Nonresolving inflammation is a key factor in diseases like atherosclerosis.
  • Inflammation resolution is a biological program to restore tissue homeostasis.
  • Endogenous specialized proresolving lipid mediators (SPMs) regulate this resolution process.

Purpose of the Study:

  • To review recent findings on inflammation-resolution dysregulation in atherosclerosis.
  • To explore the role of SPM receptors and lipid mediator imbalances in atherosclerosis.
  • To highlight potential therapeutic strategies targeting SPM pathways.

Main Methods:

  • Review of experimental studies on inflammation and atherosclerosis.
  • Analysis of the balance between SPMs and proinflammatory mediators.
  • Investigation of SPM administration effects on atherosclerotic plaques.

Main Results:

  • Lipid mediator imbalances are associated with atherosclerotic plaque instability.
  • Administration of SPMs has been shown to stabilize atherosclerotic plaques.
  • SPMs demonstrate protective effects in other cardiovascular disease models.

Conclusions:

  • Dysregulated inflammation-resolution contributes to atherosclerosis.
  • Targeting SPM receptors and correcting lipid mediator imbalances presents therapeutic opportunities.
  • SPM-based therapies may offer new avenues for treating cardiovascular diseases.
