Abstract

Insights

Platelet microparticles (PMPs) are elevated in asthma patients, suggesting they may serve as novel biomarkers for the condition and play a role in its development.

Area of Science:

  • Biomedical research
  • Respiratory medicine
  • Cellular biology

Background:

  • Endothelial microparticles (EMPs) and platelet microparticles (PMPs) are implicated in inflammatory diseases.
  • These microparticles are key mediators of intercellular communication.

Purpose of the Study:

  • To investigate microparticle levels in asthma patients.
  • To determine if microparticles can serve as biomarkers for asthma.

Main Methods:

  • Cross-sectional study comparing 20 asthmatic and 15 nonasthmatic subjects.
  • Assessed circulating microparticles, inflammatory markers, and angiogenic markers.
  • Utilized flow cytometry and immunoassays for analysis.

Main Results:

  • Significantly increased circulating levels of PMPs (CD31+/42b+ or CD31+/42b+/AnV+) were observed in asthmatics (P = 0.021).
  • Apoptotic EMPs (CD31+/42b--/AnV+) showed increased levels before adjustment (P = 0.005) but not after.

Conclusions:

  • Platelet microparticles (PMPs) show potential as reliable asthma biomarkers.
  • PMPs may play a significant role in the underlying pathophysiology of asthma.

Structure and Function of Platelets

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
