LEUKOTRIENE B Meaning and
Definition
-
Leukotriene B is a bioactive compound that belongs to a class of molecules called leukotrienes. Leukotrienes are potent mediators of inflammation in the body and are derived from arachidonic acid, an essential fatty acid.
Leukotriene B is produced by various cells in the body, including white blood cells and mast cells, in response to inflammation or injury. It plays a crucial role in the modulation of immune response and the initiation of an inflammatory cascade.
Once released, leukotriene B acts by binding to specific receptors on target cells, primarily in the respiratory system. This binding triggers a series of cellular responses, leading to increased vascular permeability, smooth muscle contraction, and the recruitment of other immune cells to the site of inflammation. These actions result in symptoms commonly associated with allergic reactions, such as bronchoconstriction, mucous secretion, and tissue swelling.
Leukotriene B is particularly involved in the pathogenesis of asthma and allergic rhinitis, as increased levels of this molecule have been detected in the airways of affected individuals. Consequently, drugs that block the actions of leukotriene B, called leukotriene modifiers or leukotriene receptor antagonists, are commonly prescribed to manage these conditions.
In summary, leukotriene B is a bioactive compound produced during an inflammatory response. It plays a pivotal role in initiating and perpetuating allergic reactions, especially in the respiratory system, and is therefore a target for pharmacological intervention.
Common Misspellings for LEUKOTRIENE B
Etymology of LEUKOTRIENE B
The word "Leukotriene" comes from the combination of two Greek roots: "leukos" meaning "white" and "treis" meaning "three". This is because the initial leukotrienes discovered were three conjugated double bonds containing lipids.
The suffix "B" in "Leukotriene B" denotes the specific sub-classification of the leukotriene family. Leukotriene B is one of the various subtypes of leukotrienes that have been identified (e.g., Leukotriene A, Leukotriene C, etc.). The use of letters such as A, B, C, etc. helps differentiate between the different subclasses within the leukotriene family.
