Annie Curtis reports
Our Immune-clock laboratory has a real interest in metabolism and how alterations in metabolic pathways termed “metabolic reprogramming” can shape the type of immune response. This area called “Immunometabolism” has exploded in the last 5 years, and the implications are massive. It appears that macrophages use one metabolic pathway to become highly proinflammatory and another metabolic pathway to resolve inflammation and promote wound healing. So why is our laboratory so interested in this? Well, if you think about daily changes in our environment, the two biggest are the sleep/wake cycle and the other is feeding/fasting. It is now clear that clocks in metabolic tissues like the liver/pancreas/adipose tissue prepare the body to deal with this daily rhythm in feeding/fasting. Based on this, our interest is to figure out if the clock within macrophages is somehow altering its metabolism over the course of the day and is that leading to changes in macrophage function, particularly the inflammatory response.
