Inflammatory Profile

Extra virgin olive oil (EVOO) represents one of the most important health-promoting foods whose antioxidant and anti-inflammatory activities are mainly associated to its polyphenols content. To date, studies exploring the effect of EVOO polyphenols on dendritic cells (DCs), acting as a crosstalk between the innate and the adaptive immune response, are scanty. Therefore, we studied the ability of three EVOO extracts (cv. Coratina, Cima di Mola/Coratina, and Casaliva), characterized by different polyphenols amount, to regulate DCs maturation in resting conditions or after an inflammatory stimulus. Cima di Mola/Coratina and Casaliva extracts were demonstrated to be the most effective in modulating DCs toward an anti-inflammatory profile by reduction of TNF and IL-6 secretion and CD86 expression, along with a down-modulation of Il-1β and iNOS expression. From factorial analysis results, 9 polyphenols were tentatively established to play a synergistic role in modulating DCs inflammatory ability, thus reducing the risk of chronic inflammation.

Aims: Rheumatoid arthritis (RA) is characterized by the onset of oxidative stress. This study aimed to evaluate the enhancing of extra virgin olive (EVOO) and Evening primrose oil (EPO) on oxidative stress and liver enzymes in male Wistar rats and compare between them. Place and Duration: Faculty of Science biochemistry department, Between July 2018 and August 2018. Methodology: A Subcutaneous injection of 200 µl of Freund's complete adjuvant into a footpad of the right hind leg of Wistar male rats at two consecutive days induced RA. Rats received EVOO and EPO daily by oral gavage needle with gauge 18 at doses of 5 mg/kg b.wt./day. for 10 and 21 days. No loss was recorded in the experimental rats. Results: A significant depletion in serum Reduced glutathione content (GSH), glutathione peroxidase (GPX), and glutathione s transferase activities (GST) in arthritic rats compared to normal rats after 10 and 21 days of induction which improved significantly after 10 and 21 days of EPO and EVOO treatments. EPO and EVOO treatments for 21 days increased the GSH and GPX compared to 10 days treatments while no difference in GST activity. EVOO treatment improved GSH and GPX after 10 and 21 days than EPO treatment. The elevated uric acid levels in arthritic rats were markedly ameliorated as a result of EVOO and EPO treatment administration. Increased lipid peroxidation products (MDA), rheumatoid factor, and liver enzyme (Alanine transaminase ALT and Aspartate transaminase AST) were recorded in arthritic rats and they significantly progressed after EPO and EVOO treatments for 10 and 21 days but EVOO had the best effect at 21 days. Conclusion: EVOO and EPO showed significant antioxidant efficacies and improved affected liver enzymes due to rheumatoid arthritis onset. When comparing olive oil has more antioxidant properties than evening primrose oil, so we recommend more studies on olive oil combination with anti-arthritic medications to improve their efficacies with less toxicity.

Background. In folk medicine, extra virgin olive oil (EVOO) is used as a remedy for a variety of diseases. This study investigates thein vivoantinociceptive, anti-inflammatory, and anti-cancer effects of EVOO on mice and rats.Materials and Methods. In this experimental study, using the acetic acid-induced writhing and formalin tests in mice, the analgesic effect of EVOO was evaluated. Acetylsalicylic acid and morphine were used as standard drugs, respectively. The anti-inflammatory activity was investigated by means of the carrageenan-induced paw edema model in rats using acetylsalicylic acid and dexamethasone as standard drugs. Last, the xenograft model in athymic mice was used to evaluate the anticancer effectin vivo.Results. EVOO significantly decreased acetic acid-induced abdominal writhes and reduces acute and inflammatory pain in the two phases of the formalin test. It has also a better effect than Dexamethasone in the anti-inflammatory test. Finally, the intraperitoneal administration of EVOO affects the growth of HCT 116 tumours xenografted in athymic mice.Conclusion. EVOO has a significant analgesic, anti-inflammatory, and anticancer properties. However, further detailed studies are required to determine the active component responsible for these effects and mechanism pathway.

Paraoxonase 1 (PON1) is associated with HDL and modulates the antioxidant and anti-inflammatory role of HDL. The goals of the present study were to investigate the effect of ageing and the role of PON1 on the anti-inflammatory activity of HDL, and to determine whether extra-virgin olive oil (EVOO) consumption could improve the atheroprotective activity of HDL. HDL and PON1 were isolated from the plasma of ten young (Y-HDL and Y-PON1) and ten elderly (E-HDL and E-PON1) healthy volunteers before and after 12 weeks of EVOO consumption. Inflammation was assessed by measuring intracellular adhesion molecule 1 (ICAM-1) expression. THP-1 (human acute monocytic leukaemia cell line) monocyte chemotaxis was measured using a Boyden chamber. Oxidative damage to HDL was assessed by measuring conjugated diene formation and changes in electrophoretic migration. Y-HDL had more anti-inflammatory activity than E-HDL. The conjugated diene content and the electrophoretic mobility of E-HDL were higher than those of Y-HDL. Y-PON1 had significant anti-inflammatory activity, reducing ICAM-1 expression by 32·64 (sd 2·63) %, while E-PON1 had no significant effect. THP-1 chemotaxis measurements confirmed the ICAM-1 expression results. The 12 weeks of EVOO consumption significantly increased the anti-inflammatory activities of both HDL and PON1. The anti-inflammatory activity of HDL was modulated by PON1 and was lower in the elderly volunteers. EVOO consumption increased the anti-inflammatory effect of HDL and reduced the age-related decrease in anti-atherogenic activity.
