Researchers have manipulated the immune system to respond more aggressively to cancer according to a new study [1]. Manipulating macrophages We have discussed modulating the immune system multiple times recently, especially in regards to macrophages and manipulating their behavior. Macrophages are part of the innate immune system and carry out a wide variety of tasks,…

We have talked about the polarization of macrophages in a number of previous articles, but, in short, macrophages can have multiple behavioral profiles that determine what roles they play; this is known as polarization. A new study has identified a regulatory protein that controls this process. Macrophage Polarization For the purposes of this article, we…

The immune system is like an army keeping us safe from invasion, injury and infection and helps us to regenerate and repair tissues and organs. However, the immune system is sometimes a double-edged sword that does more harm than good. A lot of focus has been on the role of macrophages and their ability to…

The immune system plays a key role in tissue regeneration, and the various types of immune cells, such as macrophages, can help or hinder that repair process. Inflammation is part of the immune response, but with aging that immune response becomes deregulated and the inflammation becomes excessive. Excessive levels of inflammation generally speaking inhibit tissue…

As we reported in an article yesterday, researchers are becoming increasingly interested in the potential of changing the ratio of types of macrophages present in the body to facilitate tissue regeneration and healing. This is a line of research that covers a number of topics, including aging, regeneration, tissue repair, and inflammation. Over the last…

Today we will be looking at a new study that is attempting to treat atherosclerosis, one of the biggest age-related killers globally. As we age, our risk of developing atherosclerosis rises along with related conditions, such as hypertension. We will be taking a look at new research that has reversed atherosclerosis in mice and is…
