#Fennel's #Anethole Modulates the Immune Reponse Against The Onset of Acute Inflammation and Chronic Inflammatory Diseases, Scientists Find

Kyle J. Norton

Fennel may process a strong anti-inflammatory activity in reducing the risk of tissue injury and cell apoptosis, some scientists suggested.

Acute inflammation is a natural and systematic immune response to protect our body against the invasion of foreign bacteria and viruses by the initiated production of inflammatory cytokines to the site of infection.

However, overproduction of pro-inflammatory cytokines initiated by the immune system for a prolonged period of time may lead to cell damage and sometimes death of the healthy cells in the infectious site and nearby cells.

These complications can also cause improper healing for the forming of scars and damage to the tissue of the organ, affecting and limiting the organs functioning, such as liver scars caused by hepatitis virus infection.

Badly enough, some proteins process the duo functions of pro and anti-inflammation. Under abnormal conditions, they can switch from their original action of anti-inflammatory cytokines to pro-inflammatory cytokines.

Furthermore, chronic inflammation occurs that lasts for months or years when the immune system response to the site of infection failure to eliminate agents that cause acute inflammation.

An autoimmune disorder attacks normal healthy tissue, mistaking them for pathogens that can also cause chronic inflammatory disease.
Most cases of inflammation, are treated with NSAID's, or non-steroidal anti-inflammatory drugs. However, in some people intake of these medications can cause common and serious side effects, including gastrointestinal issues, such as pain, constipation, diarrhea, gas, nausea, stomach ulcers, kidney problems, anemia,.... and swelling in the leg.

If you are presently taking anti-inflammatory medicine, please make sure that you discuss the adverse effects with your doctor.

Fennel (Foeniculum vulgare) is a plant species, belongings to Apiaceae (Umbelliferae), native to the Mediterranean.

Herbal medicine has been used in traditional and herbal medicine as a warming, carminative, antispasmodic, antidepressant agent and to stimulate the appetite, ease indigestion, soothe coughing, reduce intestinal spasms, regulate the menstrual cycle, and relieve PMS,...

According to a study of BALB/C mice were intraperitoneally administered anethole (62.5, 125, 250, or 500 mg/kg) 1 h before intratracheal treatment with LPS (1.5 mg/kg) and sacrificed after 4 h, researchers found that in the anethole treatment group exerts a significant increase of numbers of mobile white blood cells macrophages and neutrophils, the first immune response to the infectious site.

Furthermore, the application of LPS also induced the production of inflammatory mediators such as matrix metalloproteinase 9 (MMP-9), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) all systematic inflammatory cytokines in response to cellular damage and tissue injury.

Moreover, LPS also exhibited the overproduction of nitric oxide (NO) observed in bronchoalveolar lavage fluid in facilitated cellular cytotoxicity.


Compared to the nontreatment group, the injection anethole group demonstrated a strong anti-inflammatory effect through decreased activities of proinflammatory factors without affecting the immune activity in protecting against infection.

Additional analysis also found that the treatment group reduced acute lung injury caused by injection of LPS through its antioxidants and induced production of host natural antioxidants in the body tissue.

The inhibited LPS results were attributed to anethole effect in suppressed the activation of NF-κB in signaling the production of inflammatory cytokines by blocking the initiation of IκB-α degradation by inhibited TRAF2 in the induction of inflammation through TNF receptor superfamily members and NIK, a key signaling molecule of the noncanonical NF-κB.

Interestingly, further investigation of anethole as an inhibitor of TNF-induced NF-kB activation (an early response) as monitored by electrophoretic mobility shift assay, by suppression of IkBa phosphorylation and NF-kB reporter gene, researchers also indicated that

* Anethole also suppressed TNF-induced activation of the transcription factor AP-1 in regulated gene expression in response to a variety of stimuli, including LPS application.

*c-Jun N-terminal kinases (JNKs) with function in response to stress stimuli, such as cytokines,
And

* MAPKkinase in signal inflammatory response through transmitting information from a receptor on the surface of the cell to the DNA in the nucleus of the cell.


* Application of anethole also suppressed TNF-induced both lipid peroxidation and ROS generation, through the stimulated production of natural antioxidants in the host and itself, resulting in balancing the ratio of antioxidant and ROS expression.

The illustration and differentiation were elite by the experiment in the application of TNF (100 pM) with the cells pretreated for 240 and 120 min with anethole, NF-kB activation was almost completely inhibited.

However, the inhibition decreased gradually with decreased pre-incubation time.

Taken together, fennel and its bioactive anethole may be considered as a functional food in reduced risk and treatment in acute and chronic inflammatory related-diseases through the properties like a pro-antioxidant and anti-inflammatory agent.
