(LOO koh TRY een): Chemical mediator which participates in the inflammatory response.
A type of chemical involved in inflammation. Leukotrienes seem to play a particularly important role in the inflammation associated with asthma. Recently some asthma medicines have been developed that work to reduce leukotrienes or their effects (these are called "leukotriene modifiers" or "leukotriene inhibitors").
A proinflammatory immune system modulator that is released during and after allergic reactions and is also believed to be partly responsible for prolonging other types of inflammation. Leukotrienes are involved in Asthma, IBD and other inflammatory diseases.
A reaction mediator released from mast cells after degranulation that causes prolonged airway constr
Inflammatory molecule thought to mediate the allergic response that causes lung constriction and muscle contraction in asthma
a type of white blood cell involved in mast cell degranulation
a chemical compound in leukocytes that mediates allergic and inflammatory reactions.
One of a group of hormones that cause the symptoms of hayfever and asthma . Derived from arachidonic acid, the leukotrienes act by mediating immediate hypersensitivity. Leukotriene modifiers that prevent the production or action of leukotrienes are used to treat hayfever and asthma. See the entire definition of Leukotriene
powerful chemical involved in inflammation and blood flow
A natural substance (mediators) involved in inflammatory reactions leading to swelling and increased airway mucus in asthma (e.g. bronchi). This chemical substance comes from arachidonic acid which is a fatty acid in cell membranes.
Arachidonic acid metabolites having potent pharmacological effects.
A powerful inflammatory mediator. Leukotriene is important in inflammation and allergic reactions because of its ability to constrict blood vessels and attract various types of immune cells.
Leukotrienes are autocrine and paracrine eicosanoid lipid mediators derived from arachidonic acid by 5-lipoxygenase.
