Abstract
The role of eicosapentaenoic acid (EPA) in fibromyalgia (FM) pain are limited. FM, defined as pain that persists for several months, is an increasing medical challenge with significant implications for patients, the economy, and society. A FM pain mouse model was performed using intermittent cold stress (ICS). Mechanical (2.07 ± 0.12 g) and thermal (4.55 ± 0.36 s) hyperalgesia was initiated after ICS induction in the FM pain mouse model. Results showed that the detrimental effects of ICS were relieved via the oral administration of EPA (100 mg/kg/day, 3.52 ± 0.12 g and 7.11 ± 0.37 s). The overexpression of the microglia, astrocyte, and toll-like receptor 4 signaling pathways was found in the nociceptive ascending pathway of FM mice, including the thalamus, somatosensory cortex, anterior cingulate cortex, and medial prefrontal cortex, which is associated with FM initiation. These phenomena could be further attenuated by EPA administration. EPA intake can be beneficial for FM management.
期刊介绍:
Journal of Functional Foods continues with the same aims and scope, editorial team, submission system and rigorous peer review. We give authors the possibility to publish their top-quality papers in a well-established leading journal in the food and nutrition fields. The Journal will keep its rigorous criteria to screen high impact research addressing relevant scientific topics and performed by sound methodologies.
The Journal of Functional Foods aims to bring together the results of fundamental and applied research into healthy foods and biologically active food ingredients.
The Journal is centered in the specific area at the boundaries among food technology, nutrition and health welcoming papers having a good interdisciplinary approach. The Journal will cover the fields of plant bioactives; dietary fibre, probiotics; functional lipids; bioactive peptides; vitamins, minerals and botanicals and other dietary supplements. Nutritional and technological aspects related to the development of functional foods and beverages are of core interest to the journal. Experimental works dealing with food digestion, bioavailability of food bioactives and on the mechanisms by which foods and their components are able to modulate physiological parameters connected with disease prevention are of particular interest as well as those dealing with personalized nutrition and nutritional needs in pathological subjects.
