A Closer Look at How Immune Cells Attack and Heal

Macrophages – immune cells that both fight infections and fix the damage they cause – are often placed into two categories: those that increase inflammation (known as “M1”) to attack, and those that decrease inflammation to begin the healing process (“M2”). Researchers in the lab of Kathryn Miller-Jensen, associate professor […]
