Macrophages and lymphocytes are both primary white blood cells of the immune system [1], [2] that frequently co-infiltrate tissue sites during chronic inflammation [3], [4], [5]. They interact functionally through antigen presentation [6], [7] and the collective production of inflammatory cytokines and enzymes [8], [9], [10], [11].

Chronic Inflammation - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 7 facts
claimGranulomatous inflammation is a specific type of chronic inflammation characterized by distinct nodular lesions or granulomas formed by an aggregation of activated macrophages or epithelioid cells, usually surrounded by lymphocytes.
claimChronic inflammation is characterized by the infiltration of primary inflammatory cells, specifically macrophages, lymphocytes, and plasma cells, into the tissue site.
claimDuring the progression of inflammation from acute to chronic, the composition of white blood cells changes as macrophages and lymphocytes replace short-lived neutrophils.
claimTissue macrophages and dendritic cells contribute to antigen clearance through phagocytosis, the release of cytokines, and by serving as antigen-presenting cells to lymphocytes.
claimNonspecific proliferative chronic inflammation is characterized by the presence of non-specific granulation tissue formed by the infiltration of mononuclear cells, such as lymphocytes, macrophages, and plasma cells, alongside the proliferation of fibroblasts, connective tissue, vessels, and epithelial cells, as seen in nasal or cervical polyps and lung abscesses.
claimIn chronic inflammation, infiltrating macrophages, lymphocytes, and plasma cells produce inflammatory cytokines, growth factors, and enzymes, which contribute to tissue damage progression and secondary repair processes such as fibrosis and granuloma formation.
claimThe hallmarks of chronic inflammation include the infiltration of primary inflammatory cells—specifically macrophages, lymphocytes, and plasma cells—into the tissue site, where they produce inflammatory cytokines, growth factors, and enzymes that contribute to tissue damage and secondary repair processes like fibrosis and granuloma formation.
