Study Notes
Autacoids and Hormones
- Autacoids are locally acting agents that are derived from cells and act on nearby cells or tissues to produce a response.
Storage of Histamine
- Histamine is primarily stored in the body in mast cells and basophils.
Vasoactive Eicosanoids
- Leukotriene is an example of a vasoactive eicosanoid.
Autacoids vs Hormones
- The main difference between autacoids and hormones is that autacoids act locally, whereas hormones act at a distance from their site of production.
Non-Autacoid
- Insulin is NOT considered an important autacoid.
