|September 11, 2018
Summary
Nothrombel effectively inhibits platelet-leukocyte complex formation, showing greater potency than Aspirin. This compound offers a promising new avenue for managing conditions related to platelet aggregation and inflammation.
Area of Science:
- Biochemistry
- Pharmacology
- Immunology
Background:
- Platelet-leukocyte complexes (PLCs) play a role in thrombosis and inflammation.
- Thrombin is a key activator of PLC formation.
Purpose of the Study:
- To investigate the effect of Nothrombel on thrombin-induced PLC formation.
- To compare the efficacy of Nothrombel with Aspirin in inhibiting PLC formation.
Main Methods:
- Dose-dependent inhibition assays were performed.
- Half maximal effective concentration (EC50) was determined for Nothrombel and Aspirin.
- Mechanisms of inhibition were explored, including P-selectin translocation, GPIb-IX-V expression, calcium mobilization, and P2Y12 receptor activity.
Main Results:
- Nothrombel demonstrated dose-dependent inhibition of PLC formation.
- Nothrombel exhibited higher activity than Aspirin, with an EC50 of 1.75 mMol/mL compared to Aspirin's >2.5 mMol/mL.
- Nothrombel inhibited P-selectin translocation, GPIb-IX-V expression, and calcium mobilization.
Conclusions:
- Nothrombel is a potent inhibitor of platelet-leukocyte complex formation.
- Nothrombel's mechanism involves multiple pathways, including P-selectin translocation and P2Y12 receptor inhibition.
- Nothrombel represents a promising therapeutic agent for conditions involving platelet activation.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

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...

Disorders of Leukocytes
2.0K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Classification of Leukocytes
5.9K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.

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...
