Cells of the immune system have been shown to produce specialized pro-resolving mediators (SPMs), a group of lipid molecules that coordinate the active resolution of inflammation. However, the capacity for non-immune cells types to biosynthesize SPMs is not well understood. In this publication, Chatterjee A et al. aimed to examine this ability by using freshly harvested segments of aortic branch as well as vascular smooth muscle cells and vascular endothelial cells all isolated from human volunteers perioperatively. The vascular cells…

15. Insights from the Metagenics Lifestyle Summit 2015 in Phoenix, AZ: Charles Serhan, PhD In this short video, Dr. Charles Serhan discusses the differences between specialized pro-resolving mediators (SPMs) formulations for clinical application. He indicates that different product formulations must be assessed for efficacy for specific uses. Further, SPMs themselves are natural molecules and are not all created equally. They are tissue-specific, so some promote tissue regeneration while others are more effective at phagocytosis, for example.

12. Insights from the Metagenics Lifestyle Summit 2015 in Phoenix, AZ: Charles Serhan, PhD Specialized pro-resolving mediators (SPMs) offer an exciting opportunity to treat and manage the inflammation often associated with chronic disease. The precursors to SPMs are omega-3 essential fatty acids, EPA and DHA. In this short video with Dr. Charles Serhan of Harvard Medical School, Metagenics Institute inquires about whether it is possible for humans to consume too much EPA and DHA. Dr. Serhan responds that it may…

Results from a supplementation trial demonstrated that the combination of probiotics and omega-3 fatty acids reduced the risk for steatosis (fatty liver) in patients with nonalcoholic fatty liver disease (NAFLD)1. Previous research has shown that modulation of the gut microbiota via probiotics supplementation may have beneficial effects on the gut-liver axis and metabolic and immunologic responses, and omega-3 supplementation may improve liver lipid metabolism and adipose tissue function. 2,3 Seeing the potential, researchers from the Bogomolets National Medical University (Kiev, Ukraine)…

This downloadable article discusses the relationship between bacterial infections and acute inflammation. Underlying mechanisms for how bacterial infections contribute to active resolution of acute inflammation are unknown. Here, we performed exudate leukocyte trafficking and mediator-metabololipidomics of murine peritoneal Escherichia coli infections with temporal identification of pro-inflammatory (prostaglandins and leukotrienes) and specialized pro-resolving mediators (SPMs). In self-resolving E. coli exudates (10(5) colony forming units, c.f.u.), the dominant SPMs identified were resolvin (Rv) D5 and protectin D1 (PD1), which at 12 h were…

Acute inflammation is normal and protective to the host, but when inflammation becomes chronic, it can damage tissues and be destructive to health. The resolution of inflammation involves several key steps: the termination of neutrophil recruitment, counterregulation of proinflammatory mediators, stimulation of macrophage-mediated clearance, and tissue remodeling. This review of the evidence by leading experts explains how the failure of inflammation resolution contributes to metabolic diseases and the pivotal role that specialized pro-resolving mediators (SPMs), resolvins, protectins, and maresins, play…

Metabolic syndrome (MetS) is a chronic health condition comprised of a group of risk factors that raise the risk of developing cardiovascular disease, diabetes, and stroke. The National Institutes of Health (NIH) identified five risk factors that indicate that a patient may have MetS. These include a large waistline, elevated triglycerides, low HDL cholesterol, high blood pressure, and high fasting blood glucose. As prevalence and incidence of obesity increase globally, the risk of developing MetS increases as well. The NIH indicates that…

Pathology & Prevalence of Asthma Asthma is a common chronic respiratory disorder that is characterized by “asthma attacks” during which airflow is obstructed. The Centers for Disease Control and Prevention report that in the prevalence of asthma among children is 8.6% and among adults is 7.4%. While boys are likelier than girls to have asthma, adult women are almost twice as likely to have asthma than are adult men. African Americans have the highest prevalence of asthma, at 9.9%. The prevalence has…

Osteoarthritis (OA) and rheumatoid arthritis (RA) are both inflammatory disorders that affect the cartilage and the lining of the joints, respectively. The Cleveland Clinic indicates that osteoarthritis is the most prevalent form of arthritis in the United States. It affects more than 70% of adults between 55 and 78 years of age, more commonly affecting women than men. The earliest symptoms of OA are joint stiffness, pain, and swelling. It is most common in the knee, hip, spine, and hands. Activity and…

Intuitively, we understand that our health status declines as we age. Increasing incidence of morbidity associated with chronic diseases leads to reduced mobility in our elder years, which has downstream effects on our mental health and overall quality of life as we age. Research is showing us that many of the chronic conditions associated with aging are actually themselves associated with low-grade systemic inflammation, not resulting from any specific injury. This confluence of health conditions that emerge in advancing age…
