Hydroxytyrosol (HT) is a simple phenol compound present in olive oil. In a previous in vitro study, we showed that HT downregulated lipopolysaccharide-mediated expression of inducible nitric oxide synthase, cyclooxygenase-2 (COX-2), tumor necrosis factor alpha, and interleukin-1β, resulting in
Hydroxytyrosol acetate (HT-AC), a polyphenolic compound in olive oil, exerts an anti-inflammatory effect on murine collagen-induced arthritis. However, the effect of HT-AC on inflammatory response in cardiovascular disease remains unclear. Thus, in this study, we aimed to investigate the effect of
Virgin olive oil is the primary source of fat in the Mediterranean diet, and its beneficial health effects have been related with oleic acid and phenolic compounds content. Hydroxytyrosol, a typical virgin olive oil phenolic compound, has beneficial antioxidant and anti-inflammatory properties as
Hydroxytyrosol (HT), a primary phenolic antioxidant in olive oil, can afford protection from oxidative stress (OS) in different cells, including skin cells. In particular, it regulates several inflammation-associated processes as well as in improving the antioxidant defense system. However, there is
Atopic dermatitis is a multifactorial immune-mediated skin disorder characterized by an alteration of epidermal barrier function and onset of skin lesions, which range from mild erythema to severe lichenification. Treatment consists in hydration with possible use of topical or Hydroxytyrosol (HT) is among the main bioactive ingredients isolated from olive tree with a variety of biological and pharmacological activities. In the current study, the antioxidative and anti-inflammatory activities of HT were distinguished in the splenic tissue following lipopolysaccharide
Objective: Acute liver injury (ALI) leads to inflammatory response and tissue damage. Inflammatory activation of infiltrative macrophages plays a critical role in liver histology destruction and dysfunction. Hydroxytyrosol
OBJECTIVE
Evaluate the efficacy of hydroxytyrosol in the local treatment of inflammatory colitis. Currently, the existing treatments for inflammatory bowel diseases does not cure the disease and it is associated with high rates of side effects and complications. Hydroxytyrosol is a
Numerous studies have been carried out on the bioactive properties of hydroxytyrosol (HT) in olive oils (OOs), although there are few reports comparing anti-inflammatory activity among different olive varieties or regions of production. The purpose of this study was to investigate the in
Functional roles of the angiotensin peptides of the renin-angiotensin system (RAS) cascade can be analyzed through their corresponding proteolytic regulatory enzymes aspartyl aminopeptidase (ASAP), aminopeptidase A (APA), aminopeptidase B (APB), aminopeptidase N (APN) and insulin-regulated
Previous studies have shown that hydroxytyrosol (HT) can be a potential alternative therapeutic agent for the treatment of rheumatoid arthritis (RA). However, HT is extensively metabolized following oral administration, which leads to formulating HT in a topical vehicle to prolong drug action as
Advanced oxidation protein products (AOPPs) can trigger NADPH oxidase (NOX) and lead to the production of reactive oxygen species (ROS) in the pathophysiology of rheumatoid arthritis (RA). Hydroxytyrosol (HT) is a phenolic composite in olive oil that has antioxidant and anti‑inflammatory effects and
BACKGROUND
Olive oil intake has been shown to induce beneficial effect on health. This study aimed to investigate the effects of olive oil polyphenol hydroxytyrosol (HT) on cell proliferation and its antioxidant and anti-inflammatory capacity in human hepatoma Hep3B and HepG2 cell
Chronic inflammation of the adipose tissue (AT) is a major contributor to obesity-associated cardiometabolic complications. The olive oil polyphenol hydroxytyrosol (HT) contributes to Mediterranean diet cardiometabolic benefits through mechanisms still partially unknown. We investigated HT (1 and 10
Discovery of potential lead molecule is a challenging, and complex process which require lots of money, patience, and manpower. Human beings are using natural products, predominantly secondary metabolites, for this purpose since ancient time and they are still working on them as a potent source for
