   * **EPA and DHA switch off a key receptor responsible for innate immunity in fat cells.**  Olefsky and colleagues identified a key receptor on macrophages abundantly found in obese body fat: the GPR120 receptor.(({{pubmed>long:20813258}})) The team showed that omega-3 fatty acids activate this macrophage receptor, resulting in broad anti-inflammatory effects. [[http://www.eurekalert.org/pub_releases/2010-09/uoc--wfo083010.php|Commenting about his work]], Olefsky said, "It's just an incredibly potent effect. The omega-3 fatty acids switch on the receptor, killing the inflammatory response."

+<blockquote>Although fish oil-fed mice had lower lung inflammation compared with controls, fish oil feeding also resulted in a 40% higher mortality rate, a 70% higher lung viral load at d 7 post infection, and a prolonged recovery period following infection.... Additionally, lungs of infected fish oil-fed mice had significantly fewer CD8+ T cells and decreased mRNA expression of macrophage inflammatory protein-1-alpha, tumor necrosis factor-alpha, and interleukin-6. These results suggest that the antiinflammatory properties of fish oil feeding can alter the immune response to influenza infection, resulting in increased morbidity and mortality.

+Omega-3 linked to aggressive prostate cancer
+By Laura Dean
+May 2011
+Am J Epidemiol 2011; Advance online publication
+MedWire News: High levels of omega 3 (n-3) fatty acids, which are considered beneficial for coronary artery disease prevention, may increase the risk for high-grade prostate cancer, US research shows.
+In contrast, trans-fatty acids (TFAs), abundant in processed foods that contain partially hydrogenated vegetable oils and considered harmful, may reduce high-grade prostate cancer risk, report Theodore Brasky (Fred Hutchinson Cancer Research Center, Seattle, Washington) and colleagues.
+"We were stunned to see these results and we spent a lot of time making sure the analyses were correct," said Brasky. "Our findings turn what we know - or rather what we think we know - about diet, inflammation and the development of prostate cancer on its head and shine a light on the complexity of studying the association between nutrition and the risk of various chronic diseases."
+Brasky and team examined the association between inflammation-related phospholipid fatty acids (n-3, n-6, and TFAs) and prostate cancer risk because chronic inflammation is known to increase the risk of several cancers, and n-3 fatty acids, found primarily in fish and fish oil supplements, have anti-inflammatory effects.
+They conducted a case-control analysis of 3461 men (1658 cases and 1803 controls) aged 55-84 years, who participated in the Prostate Cancer Prevention Trial between 1994 and 2003.
+As reported in the American Journal of Epidemiology, men with the highest levels of the n-3 fatty acid docosahexaenoic acid (>3.30% of total fatty acid) had a 2.5-fold greater risk for high-grade prostate cancer (Gleason scores 8-10) than those with the lowest levels (<2.26% of total fatty acid).
+In contrast, men with the highest levels of TFA 18:1 (>2.08% of total fatty acid) and TFA 18:2 (>0.26% of fatty acid) had a respective 45% and 52% lower risk for cancer than those with the lowest levels (<1.29% and <0.18% of total fatty acid, respectively).
+Of note, no other fatty acids were associated with high-grade prostate cancer risk, and none were associated with low-grade prostate cancer risk (Gleason scores 2-7).
+In spite of the findings, the researchers do not recommend that men should stop taking fish oil supplements or eating oily fish. "Overall, the beneficial effects of eating fish to prevent heart disease outweigh any harm related to prostate cancer risk," Brasky said.
+"A comprehensive understanding of the effects of nutrients on a broad range of diseases will be necessary before making recommendations for dietary changes or use of individual dietary supplements for disease prevention," the team concludes.</blockquote>
