Autacoids are enzymatically derived chemical mediators with distinct biological activities and molecular structures.
2.
The activating stimulus may include bacterial lipopolysaccharides, muramyl dipeptide, and other chemical mediators.
3.
When mast cells degranulate, the release of chemical mediators ( histamine, cytokines ) leads to allergic symptoms and possibly anaphylaxis.
4.
His research contributions included work on correlating skin diseases with calcium metabolism and parathyroid hormone, and vascular chemical mediators involved in cutaneous inflammation.
5.
Typically, in other forms of shock, the sympathetic nervous system triggers various compensatory mechanisms by releasing epinephrine and norepinephrine, its major chemical mediators.
6.
Szczeklik's main research interest included : cardiopulmonary diseases, aspirin-induced asthma, chemical mediators in diseases of circulatory and respiratory systems with special reference to eicosanoids.
7.
Macrophages are responsible for the production of various cytokines, RNS and ROS, growth factors and chemokines as a response to activation signal such as chemical mediators, cytokines and lipopolysaccharide.
8.
The mechanism that is thought to have a significant influence on delayed effects involves formed blood cells and chemical mediators, which cause brain lipid peroxidation ( degradation of unsaturated fatty acids ).
9.
In periodontitis, however, the chemical mediators, or by-products, of chronic inflammation stimulate the osteoclasts, causing them to work more rapidly than the cells that build bone.
10.
Activated mast cells and basophils undergo a process called degranulation, during which they release histamine and other inflammatory chemical mediators ( cytokines, interleukins, leukotrienes, and prostaglandins ) from their smooth-muscle contraction.
