Polyunsaturated fatty acids (PUFAs) are normal constituents of the diet, but have properties different from other fatty acids (e.g., through generation of signaling molecules). N-3 PUFAs reduce cancer cell growth, but no unified mechanism has been identified. We show that docosahexaenoic acid (DHA; 22:6 n-3) causes extensive changes in gene expression(More)
It is believed that chemokines and their receptors are involved in trafficking of T-cells to the central nervous system (CNS). The aim of the current study was to define the expression on cerebrospinal fluid (CSF) T-cells of six chemokine receptors associated with trafficking to sites of inflammation. Flow cytometry was used to detect chemokine receptor(More)
The expression of delta 5 desaturase (D5D), delta 6 desaturase (D6D) and delta 9 desaturase (D9D) was determined by RT-PCR in the human promyelocytic cell line HL60. During 72 h of culture with 10% FBS, D5D and D6D were upregulated 5 to 6-fold, whereas D9D approximately doubled. The addition of fatty acids (FAs) to the culture medium suppressed upregulation(More)
Associations between and changes in plasma phospholipid fatty acid (FA) concentrations and expression of delta 5 desaturase (D5D), delta 6 desaturase (D6D) and delta 9 desaturase (D9D) in leucocytes were investigated both before and during n-3 FA supplementation for 2 weeks in 20 healthy individuals. Participants were divided into two groups depending on(More)
Vasoactive metabolites deriving from arachidonic acid (AA) have been considered as putative mediators in the pathogenesis of various types of headache. In the present study we therefore compare the ability to synthesize AA containing precursor phospholipids in polymorphonuclear cells (PMNs) from healthy controls and cluster headache patients. 3.7% +/- 1.4(More)
Prostaglandins and leukotrienes have been implicated in the pathogenesis of various types of headache, mainly because some, but not all, cyclo-oxygenase inhibitors are effective in their treatment. We have therefore investigated whether a pathologically changed turnover of arachidonic acid (AA)-containing phospholipids can be seen in headache patients,(More)
