Both are antigen presenting cells that derive from monocytes. So then why are dendritic cells specifically called “professional antigen presenting cells” when macrophages present antigens as well?
hello! i made a search and here is what I found,
‘Macrophages and neutrophils scavenge and destroy phagocytosed particles, a critical step in innate immunity. DCs, in contrast, have developed means to ‘preserve’ useful information from the ingested particles that serve to initiate adaptive immune responses’
hope this helps
