makrofagai

Makrofagai are a type of white blood cell that plays a crucial role in the immune system of vertebrates. They are part of the mononuclear phagocyte system, which also includes dendritic cells and other types of phagocytes.

Makrofagai are large, specialized cells that can engulf and digest foreign substances, including bacteria, viruses, and dead cells. They are particularly effective at removing pathogens and other debris from tissues and organs. The name "makrofagai" is derived from the Greek words "makros," meaning large, and "phagein," meaning to devour.

Makrofagai are found in almost all tissues and organs of the body, including the lungs, liver, spleen, and lymph nodes. They can be further divided into several subtypes, including tissue-resident macrophages and inflammatory macrophages. Tissue-resident macrophages are resident in specific organs and tissues, where they perform critical functions, such as maintaining tissue homeostasis and monitoring for pathogens. Inflammatory macrophages, on the other hand, are recruited to sites of inflammation and infection, where they help to clear pathogens and repair damaged tissue.

Makrofagai have a number of specialized functions, including the production of cytokines, which are signaling molecules that help to coordinate the immune response. They can also present antigens to T cells, a process that is critical for the activation and differentiation of these immune cells. Overall, makrofagai play a vital role in the immune system, helping to protect the body from infection and disease.
