LEUKOTRIENES B Meaning and
Definition
-
Leukotrienes B, also known as leukotriene B or LTB, are a class of lipid mediators or signaling molecules that are derived from arachidonic acid. They are bioactive compounds involved in various physiological processes and are primarily associated with inflammatory responses in the body.
Leukotriene B is produced by the sequential enzymatic action of enzymes such as 5-lipoxygenase on arachidonic acid, which is released from cell membranes. The production of LTB occurs mainly in cells of the immune system, including leukocytes, mast cells, and macrophages.
Once produced, leukotrienes B exhibit potent biological activities. They act by binding to specific receptors, namely leukotriene receptors, present on target cells. These receptors are found predominantly on smooth muscle cells, blood vessels, and cells of the immune system.
The binding of leukotrienes B to their respective receptors initiates a cascade of events that lead to the activation of inflammatory responses, including increased vascular permeability, smooth muscle contraction, recruitment of immune cells, and synthesis of other proinflammatory molecules.
In addition to their role in inflammation, leukotrienes B also play a role in certain diseases and conditions such as asthma, allergic rhinitis, and other allergic reactions. They are also involved in the regulation of immune responses and have been implicated in allergic skin disorders, cardiovascular diseases, and even cancer.
In summary, leukotrienes B are bioactive lipid mediators derived from arachidonic acid and are primarily associated with inflammation. They bind to specific receptors, initiating a range of inflammatory responses and are involved in various physiological processes and pathological conditions.

Etymology of LEUKOTRIENES B
The word "Leukotrienes B" is derived from two sources: "leuko-" and "triene".
1. "Leuko-" comes from the Greek word "leukos", meaning "white". In the context of "leukotrienes", "leuko-" refers to their initial association with leukocytes, which are white blood cells involved in the immune response.
2. "Triene" is a chemical term referring to a compound with three double bonds. In the case of leukotrienes, they are lipid-based molecules derived from the polyunsaturated fatty acid, arachidonic acid, that contain three double bonds.
Therefore, "leukotrienes B" signifies a class of lipid molecules derived from leukocytes (white blood cells) that contain three double bonds in their structure.
