Therapeutic effect of NEO400, perillyl alcohol conjugated to linoleic acid, in a mouse model of UV‐induced skin damage

Photochemistry and Photobiology, Volume 101, Issue 2, Page 338-349, March/April 2025.
In the present work with mouse models, we demonstrate that a novel compound, NEO400, is able to profoundly protect skin against damage caused by UV radiation (UVR) when it is applied to skin post‐UVR exposure. In comparison, Aloe vera or linoleic acid are unable to achieve a similar level of protection.

Inhibition of the MALT1-LPCAT3 axis protects cartilage degeneration and osteoarthritis

Cell Communication and Signaling
The proinflammatory cytokines and arachidonic acid (AA)-derived eicosanoids play a key role in cartilage degeneration in osteoarthritis (OA). The lysophosphatidylcholine acyltransferase 3 (LPCAT3) preferentially incorporates AA into the membranes.

Time Dependent Production of Cytokines and Eicosanoids by Human Monocytic Leukaemia U937 Cells; Effects of Glucocorticosteroids

Mediators of Inflammation, 1999
In the present study the human monoblast cell line U937 has been used as a model to study the function of human mononuclear phagocytes in asthma. The kinetics of the production of eicosanoids and cytokines, which are thought to play a role in the ...

Effects of sodium humate and zinc oxide used in prophylaxis of post-weaning diarrhoea on the health, oxidative stress status and fatty acid profile in weaned piglets

Veterinární Medicína, 2017
The aim of this study was to investigate the effects of sodium humate (HNa), applied to feed or drinking water as a partial substitution for pharmacological doses of ZnO, on clinical, biochemical and haematological indicators of health status, oxidative ...

The phosphoinositide 3-kinase-dependent activation of Btk is required for optimal eicosanoid production and generation of reactive oxygen species in antigen-stimulated mast cells

, 2008
Activated mast cells are a major source of the eicosanoids PGD(2) and leukotriene C(4) (LTC(4)), which contribute to allergic responses. These eicosanoids are produced following the ERK1/2-dependent activation of cytosolic phospholipase A(2), thus ...

Polarization of macrophages toward M2 phenotype is favored by reduction in iPLA2β (group VIA phospholipase A2)* [PDF]

, 2016
Macrophages are important in innate and adaptive immunity. Macrophage participation in inflammation or tissue repair is directed by various extracellular signals and mediated by multiple intracellular pathways.

Characterization of Eicosanoids Produced by Adipocyte Lipolysis

Journal of Biological Chemistry, 2016
Excessive adipocyte lipolysis generates lipid mediators and triggers inflammation in adipose tissue. However, the specific roles of lipolysis-generated mediators in adipose inflammation remain to be elucidated.

Possible involvement of keratinocyte‐derived microvesicle particles in human photosensitivity disorders

Photochemistry and Photobiology, EarlyView.
In this model, ROS generated by UVB result in PAFR agonists acting upon the PAFR resulting in MVP generation release via the enzyme aSMase. In photosensitivity, there are increased ROS, resulting in augmented PAF agonists and increased MVP release. This process can be blocked by aSMase inhibitors.

Cytochrome P450-derived epoxyeicosatrienoic acids and coronary artery disease in humans: a targeted metabolomics study

Journal of Lipid Research, 2016
Cytochrome P450 (CYP)-derived epoxyeicosatrienoic acids (EETs) exhibit potent cardiovascular protective effects in preclinical models, and promoting the effects of EETs has emerged as a potential therapeutic strategy for coronary artery disease (CAD ...

Exposure to polybrominated diphenyl ethers (PBDEs) suppresses the release of pro-inflammatory products by alveolar macrophages in vitro [PDF]

, 2010
Endocrine disrupting chemicals have adverse effects on immune function that may result in respiratory conditions. Inhalation of dust is a major route of exposure to PBDEs; however, the impact of PBDEs on the immune response is unclear.
