Macrophages are classified as one of the three primary cell types capable of acting as antigen-presenting cells [1], performing this role to bridge innate and adaptive immune responses {fact:4, fact:5}. They specifically function as antigen-presenting cells when processing pathogens {fact:1, fact:2} and migrating to lymph nodes to activate lymphocytes [2].

claimMacrophages primarily destroy pathogens, signal the innate immune response, and cause inflammation, though they are also capable of serving as antigen-presenting cells.
procedureDendritic cells, macrophages, and B cells must travel to the draining lymph node to activate the adaptive immune response when acting as antigen-presenting cells.
claimWhen macrophages function as antigen-presenting cells, they typically present antigens from pathogens that have evolved to evade typical innate immune responses.
claimDendritic cells, macrophages, and B cells are the three cell types that can serve as antigen-presenting cells (APCs).
3. The Innate Immune System - Immunopaedia immunopaedia.org.za 1 fact
claimMacrophages function in adaptive immune responses as antigen-presenting cells and as targets for cellular and humoral adaptive responses, where they are activated by T cell-derived cytokines and antibodies.
Chronic Inflammation - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 1 fact
claimTissue macrophages and dendritic cells contribute to antigen clearance through phagocytosis, the release of cytokines, and by serving as antigen-presenting cells to lymphocytes.
