What Is Inflammaging? How the Immune System Changes With Age
Inflammaging describes the persistent, low-level inflammatory activity that can develop as the immune system changes with age. When we think about ageing, we often notice changes in our skin, energy, strength or memory. But ageing also takes place inside the immune system—and these internal changes may influence how effectively the body responds, repairs and returns to balance. What Is Inflammaging? Inflammation is a normal and essential part of the body’s defence system. It helps the body respond to infection or injury, clear damaged material and begin the repair process. Normally, this response should settle once its work is complete. With age, however, low-level inflammatory signalling may remain active even when…

What Are Macrophages? Why They Matter for Healthy Immunity
When people think about the immune system, they often picture white blood cells fighting off bacteria and viruses. While that is true, one group of immune cells deserves special attention for its role in supporting the body every day: macrophages. Macrophages are among the first responders of the immune system. They help defend against harmful invaders, remove damaged cells, support tissue repair, and coordinate immune activity. More importantly, macrophages help maintain immune balance rather than simply making the immune system “stronger.” Understanding how macrophages work can provide valuable insight into immunity, inflammation, and healthy ageing. What Are Macrophages? Macrophages are a type of white blood cell that belongs to the…
