Cytokine secretion in macrophages and other cells: Pathways and mediators
2009
Cytokines and other immune mediators are secreted by cells of the immune system during immune responses and as a means of communication. While the functions of these cytokines, chemokines and mediators are well known, the intracellular pathways that lead to their secretion by different cells are only now being fully documented. Cytokines in some cells are released from secretory granules while in other cells they are released via constitutive secretory pathways that instead have more dynamic vesicular carriers. Recent studies have revealed that newly synthesized cytokines can be routed via compartments such as recycling endosomes prior to their secretion. Here we describe and show examples of some of the pathways used for cytokine trafficking and release in macrophages, including some of the cellular machinery required for this transport. Increasingly, these trafficking pathways are revealed as having important regulatory roles in the execution of immune responses.
