Macrophages are directly responsible for the production and secretion of chemokines, which serve as signaling molecules to recruit other immune cells to sites of inflammation as described in [1], [2], [3], and [4]. Furthermore, the activation of macrophages contributes to a feedback loop that triggers the release of additional chemokines during inflammatory responses, as noted in [5].

The Role of Immune Cells in Inflammation jmolpat.com 2 facts
claimMonocytes differentiate into macrophages, which are responsible for phagocytosing and clearing cellular debris and dead cells, producing cytokines and chemokines, and promoting tissue repair.
claimNeutrophils are among the first immune cells to arrive at the site of inflammation, attracted by chemokines produced by activated macrophages and other immune cells.
Pro-Inflammatory Cytokines Overview | Thermo Fisher Scientific - US thermofisher.com 1 fact
procedureMacrophages and endothelial cells produce large amounts of IL-6 after activation, which activates T cells and other immune cells, creating a positive feedback loop that results in a cytokine storm, the release of additional cytokines and chemokines, and the upregulation of acute phase proteins.
3. The Innate Immune System - Immunopaedia immunopaedia.org.za 1 fact
claimMacrophages perform several defense functions: phagocytosis and killing of microorganisms/infected cells/tumor cells via PAMP recognition, scavenging debris/apoptotic bodies, antigen presentation to T cells, releasing cytokines/chemokines, and regulating immunity via the alternatively activated pathway.
Chronic Inflammation - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 1 fact
claimOnce circulating leukocytes enter a local injury site, they are activated by cytokines and chemokines secreted by macrophages and dendritic cells, subsequently releasing their own cytokines and mediators of inflammation.
