The tissue modifications induced by the causal agent are responsible for the release of inflammatory mediators that lead to subsequent inflammatory events. Cytokine release IL-1, TNF-a by activated macrophages leads to vessel dilation and results in smooth muscle relaxation and increased local blood flow hypothermia. Microvascular changes associated with increased vascular permeability take place, leading to accentuated plasmatic exudation, phagocyte accumulation neutrophils, monocytes, macrophages , and amplification of endogenous chemical mediators.
Simultaneously, mast cells, phagocytic cells and endothelial cells use plasma membrane lipids to generate important inflammatory mediators In an immediately posterior stage, several intra and extracellular phospholipases are activated by cytoplasmic membrane phospholipids and activate other enzymes, such as cyclooxygenase COX and lipoxygenase LOX , which in turn act upon arachidonic acid and eicosanoid metabolism, creating important inflammatory mediators prostaglandins and leukotrienes.
These mediators are responsible for the maintenance of the inflammatory process. The fibrinolytic system, kinins, complement, vasoactive amines histamine and serotonin , and nitric oxide NO may lead to inflammation when physiologically altered Endothelial-leukocyte cellular adhesion occurs in a sequence of events, and specific molecules are expressed in different stages.
In response to several mediators, the vascular endothelium expresses specific glycoproteins on the cell surface, which mediates blood leukocyte connection and extravasation, an important event in tissue repair 3. According to the frequency and duration of the injurious agent, the inflammatory process can be classified into acute and chronic. The acute-stage response involves serous, fibrinous, suppurative or exudative events as well as microvascular and cellular events; this response to phlogogen occurs within 72h.
The chronic stage response includes proliferative events and histological alterations different from those in the acute stage, being characterized by cell emigration and intensive mitosis. Formation of giant multinuclear cells takes place, and all these events are induced by phlogogen In certain instances, inflammation must be regulated by using specific drugs, since it may lead to toxic consequences to the organism.
The damage to the organism during the inflammatory response is induced by free radicals produced by active macrophages and neutrophils. These molecules degrade lipid acids of the plasma membrane, disrupt membrane proteins, and induce DNA mutations. NO is another potent inflammatory mediator produced by endothelial and inflammatory cells that can induce tissue damage if synthesized in large quantities Some anti-inflammatory substances found in propolis have been isolated.
These compounds contribute to the suppression of prostaglandins and leukotrienes synthesis by macrophages and have inhibitory effects on myeloperoxidase activity, NADPH-oxidase, ornithine decarboxylase and tyrosine-protein-kinase Krol et al. It is known that macrophages are involved in several body physiology processes, such as phagocytosis, enzyme release, free radical generation, and inflammation. Scheller et al. The results of the study of Orsi et al. While investigating the effects of individual propolis compounds complexes on lysine, Ivanovska et al.
The inhibition of NO production by macrophages may also be responsible for propolis anti-inflammatory activity Hu et al. In these models, NO could accelerate an inflammatory reaction by enlarging blood vessels and causing edema. This could increase the expression of inflammatory reactions and accelerate the development of blood poisoning by activating prostaglandin synthesis, as seen in the progression of rheumatism.
However, other studies indicated increased NO production by macrophages Although the mechanism of WSD and EEP on anti-inflammatory performance was apparently similar, there were some differences. The results suggest that additional propolis components, other than flavonoids, possess anti-inflammatory effects. The arthritic rat model induced by FCA is associated with an immune inflammation reaction in these experiments. The main feature of rheumatoid arthritis RA is the ongoing damage in arthrosis of cartilage and bone, in addition to a disturbance of the immune function.
Cytokines secreted by immune cells lymphocyte and mononuclear-macrophage , fibroblasts, and endothelial cells play an important role in immune and inflammatory responses in vivo. This could also mean that, in the course of the anti-inflammatory activity of WSD and EEP, the humoral immune system plays an important role inhibiting the activation and differentiation of mononuclear macrophages.
Inflammation can also be related to free radicals increase in the human organism 9. Although oxidative damage is known to be involved in inflammatory-mediated tissue destruction, modulation of oxygen-free radicals production represents a new approach to the treatment of inflammatory diseases 8. Propolis contains polyphenols and a wide range of other compounds capable of removing excessive free radicals from our organism CAPE, a flavonoid-like compound, has been identified as one of the main active ingredients of honeybee propolis and has antioxidant and anti-inflammatory properties 8.
For that reason, Celik et al. The main hypothesis of events leading to renal scarring has been that bacterial products e. PNL release toxic products e. However, CAPE administration reduced malondialdehyde MDA levels, which is an indicator of free radical generation that increases in final stages of lipid peroxidation. NO levels have been implicated in the mechanisms of cell injury and long-term physiological changes in cellular excitability. In a similar study, Song et al.
CAPE administration significantly inhibited the activity of XO, a physiological source of superoxide anions in eukaryotic cells. In summary, CAPE administration decreases the oxidative damage occurring in PYN and thus could be used for medical management of bacterial nephropathy.
Several reports have shown that activation of Ras signaling pathways is involved in the induction of COX-2 and matrix metalloproteinase expression. COX catalyzes the critical conversion of arachidonic acid into prostaglandins, which are important mediators of the inflammatory process. Improper up-regulation of COX-2 is relevant to the pathophysiology of inflammatory disorders.
The eukaryotic transcription factor nuclear factor kB NF-kB plays a central role in general inflammatory as well as immune responses. In agreement with this concept, NF-kB has been shown to be a critical regulator of COX-2 expression in many cell lines In those studies, histopathological examinations showed that CAPE significantly suppressed inflammation.
Others have shown that CAPE not only inhibits transcription factors, but also reduces the production of IL-8 and monocyte chemotactic protein All the above-mentioned data have demonstrated different mechanisms of inflammatory inhibition of several propolis preparations or its isolated compounds. Nevertheless, the anti-inflammatory effects of propolis depend mainly on the administration mode and dosage Inflammation is a protective reaction of the body against injury or infection, in which the affected area becomes swollen, hot, red, and painful.
In the past, it was believed that this reaction was dangerous and that anti-inflammatory medicines were necessary. However, we now recognize inflammation as a protective and necessary response of our internal defense system, and we know that it may not always be good to block it. By studying this pro-resolving program, scientists are developing a brand new class of medicines to use when we suffer from inflammation, which will make our bodies heal faster.
Although they are still experimental, many scientists around the world believe that these will become the medicines of the future. The Roman writer Aulus Cornelius Celsus, who lived in the 1 st century AD, was the first to describe the process called inflammation.
Inflammation is the reaction of the body against injury or infection [ 1 ]. For example, during a toothache, or sore throat, or when you hit your head on a door or badly stub your pinky toe, what your body experiences is called an inflammatory reaction. The affected area turns red, it gets hot, it swells up, and it hurts.
These are the four major characteristics of inflammation described by Celsus almost 2, years ago, which is known as The Pillars of Inflammation: rubor redness , calor warmth tumor swelling , and dolor pain Figure 1. Redness occurs because the capillaries small blood vessels in the affected tissue enlarge and bring in more blood than usual.
This increase in blood flow is also responsible for the sensation of heat. Swelling happens because the tissues fill with liquid that comes out of the enlarged blood vessels. The pain sensation is caused by chemicals that stimulate the nerves endings in that area. But, what is the purpose of inflammation?
Why do we need to feel pain? Pain is essential to alert our bodies that something wrong is going on, and pain lets us know that a particular part of the body needs extra care. The other three factors heat, redness, and swelling are equally important, because they allow the immune system to come into action. The expansion of the capillaries and the increased blood flow bring the immune cells , such as neutrophils and monocytes, into the affected area.
These immune cells are our internal warriors. They are the fighters that protect us against the agents causing the inflammation, such as the flu virus causing the sore throat or bacteria that are trying to enter the body through a wound in the skin.

Always talk to a doctor before using any herbal or other supplements. Studies have suggested that people with high levels of CRP may be less likely to follow a diet that is rich in fresh products and healthy oils, such as the Mediterranean diet. Diet alone will not control inflammation, but making suitable choices may help prevent it from getting worse. Learn more here about the anti-inflammatory diet. Inflammation is part of the process by which the immune system defends the body from harmful agents, such as bacteria and viruses.
In the short term, it can provide a useful service, although it may also cause discomfort. Long-term or chronic inflammation, however, can both lead to and result from some severe and possibly life threatening conditions. People with tumors, rheumatoid arthritis, inflammatory bowel disease, drug reactions, and other health issues may have high levels of CRP, which is a sign of an inflammatory immune response.
As scientists learn more about the role of inflammation in disease, their findings could lead to more effective treatments for various illnesses that do not yet have a cure, such as type 1 diabetes.
