Mechanisms by which botanical lipids affect inflammatory disorders
ABSTRACT
Changes in diet over the past century have markedly altered the
consumption of fatty acids. The dramatic increase in the ingestion of
saturated and n 6 fatty acids and concomitant decrease in n 3 fatty
acids are thought to be a major driver of the increase in the incidence
of inflammatory diseases such as asthma, allergy, and atherosclerosis [EDIT-Dave: and glaucoma]. The central objective of the Center for Botanical Lipids at Wake
Forest University School of Medicine and the Brigham and Women’s Hospital is to delineate the mechanisms by which fatty acid–
based dietary supplements inhibit inflammation leading to chronic
human diseases such as cardiovascular disease and asthma. The key
question that this center addresses is whether botanical n 6 and n 3
fatty acids directly block recognized biochemical pathways or the
expression of critical genes that lead to asthma and atherosclerosis.
Dietary supplementation with flaxseed oil, borage oil, and echium
oil affects the biochemistry of fatty acid metabolism and thus the
balance of proinflammatory mediators and atherogenic lipids. Supplementation studies have begun to identify key molecular and genetic mechanisms that regulate the production of lipid mediators
involved in inflammatory and hyperlipidemic diseases. Echium oil
and other oils containing stearidonic acid as well as botanical oil
combinations (such as echium and borage oils) hold great promise
for modulating inflammatory diseases [EDIT-Dave: such as glaucoma].
