Insights

Platelets release antimicrobial peptides, similar to amyloid-beta (Aβ) peptides found in other cells. This review suggests platelet-generated Aβ may contribute to various amyloidosis conditions, including Alzheimer's disease.

Area of Science:

  • Immunology
  • Neuroscience
  • Biochemistry

Background:

  • Platelets, like other immune cells, release antimicrobial peptides.
  • Amyloid-beta (Aβ) peptides are implicated in various diseases.
  • The role of platelet-derived Aβ in systemic amyloidosis is under investigation.

Purpose of the Study:

  • To review the literature on antimicrobial peptides released by blood cells.
  • To explore the similarity between these antimicrobials and platelet-derived Aβ.
  • To propose that platelet-generated Aβ amyloidosis is more prevalent than currently recognized.

Main Methods:

  • Literature review and analysis.
  • Comparison of antimicrobial peptides from different cell types.
  • Discussion of animal models for studying platelet-related Aβ.

Main Results:

  • Evidence suggests similarity between platelet-derived Aβ and other antimicrobial peptides.
  • Platelet-generated Aβ may contribute to pathologies such as Alzheimer's disease, Parkinson's disease, glaucoma, and preeclampsia.
  • The systemic Aβ from platelets could play a role in various amyloidosis conditions.

Conclusions:

  • Platelet-generated Aβ peptides may be significant contributors to systemic amyloidosis.
  • Understanding the role of platelet Aβ is crucial for investigating amyloidosis-related health disorders.
  • This research area is rapidly evolving with new experimental findings.

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

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...

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...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
