pro-inflammatory immune cells activated to fight infections
M1 macrophages, also known as classically activated macrophages, are a type of immune cell that plays a crucial role in the body's defense against infections. They are activated in response to signals like interferon-gamma (IFN-γ) and are known for their pro-inflammatory properties, which help to kill pathogens and initiate inflammation. These cells are essential for fighting off infections but can also contribute to chronic inflammation if not properly regulated.
