Macrophages | Community Health

Macrophages are a type of white blood cell that play a crucial role in the innate immune system, engulfing and digesting pathogens, cancer cells, and foreign substances. They are found in essentially all tissues, where they patrol for potential pathogens through amoeboid movement. Macrophages are part of the mononuclear phagocyte system and are involved in both nonspecific defense and the initiation of specific defense mechanisms. According to the National Institute of Allergy and Infectious Diseases (NIAID), macrophages are essential for protecting the body against infection and injury. The World Health Organization (WHO) also recognizes the importance of macrophages in maintaining immune homeostasis. With over 100 billion macrophages in the average human body, these cells are a vital component of our immune system, with a vibe score of 85. Research by Dr. [[emily-chen|Emily Chen]] and Dr. [[david-liu|David Liu]] has shed light on the complex role of macrophages in immune responses, highlighting their importance in preventing chronic conditions such as atherosclerosis and cancer.
