What is the difference between macrophages and dendritic cells?
Date:2023-03-10
Macrophages are immune cells that ingest and break down cellular debris, foreign substances, and pathogens to aid in tissue repair and defense against invading organisms. They play a key role in innate immunity and in the inflammatory response. Dendritic cells are specialized immune cells that present antigens to stimulate an adaptive T-cell mediated immune response.
