Microphage vs. Macrophage: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 9, 2024
Microphages, a term rarely used in modern immunology, refers to smaller phagocytic cells, while macrophages are large, versatile immune cells involved in phagocytosis and immune regulation.

Key Differences

Microphage is an older term that was once used to describe smaller phagocytic cells, primarily neutrophils, in the immune system. Macrophages, on the other hand, are large, specialized cells that play a critical role in identifying, engulfing, and destroying pathogens and debris.

Microphages function mainly in the initial stages of the immune response, rapidly attacking pathogens. Macrophages are involved in both the initial response and the later stages of immune response, including tissue repair and the presentation of antigens to T cells.

The activity of microphages is often quick and non-specific, targeting a broad range of pathogens. Macrophages exhibit more complex behaviors, including the ability to present antigens, produce inflammatory mediators, and modulate immune responses.

Microphages, being smaller and less versatile, are limited in their ability to influence the immune response beyond the immediate phagocytic activity. Macrophages are central to both innate and adaptive immunity, influencing the overall direction and strength of the immune response.

In modern immunology, the term microphage is seldom used, with a greater focus on the specific types of phagocytic cells like neutrophils. Macrophages continue to be a major focus of research, given their crucial role in immunity, tissue homeostasis, and disease.
